Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a typesetting device such as desk top publishing (DTP), and in particular, arranging characters forming text data with a sense of perspective. The present invention relates to a typesetting processing device that performs typesetting processing.

[0002]

2. Description of the Related Art A typesetting device of this type is given a character string (generally treated as a file of text data composed of a character code corresponding to each character).
The font data corresponding to each character is output so as to be arranged at the obtained arrangement position (for example, display, printing, film printing, etc.) in accordance with the specified typesetting instruction.

A font includes a series of characters (alphanumeric characters / symbols other than character types such as kana and kanji) created based on the same typeface.
Unless otherwise noted, they have the same meaning) and are a set of dot fonts that represent characters, and today they are often composed of vector data (outline fonts, etc.).

A typeface means a design design in which a set of a series of characters is uniformly applied for printing or display based on a concept such as aesthetics. For example, Mincho typeface or italic typeface. The body, the Gothic body, etc. are known, and the font data is the data of the characters themselves that are displayed and output as such.

Here, the structure of the font data is shown in FIG.
It is defined with reference to the schematic diagram shown in FIG. In FIG. 59, the character “large” component is shown. The font shape of the character is
"Virtual body" IB, which is a rectangular frame that shows the size of characters
The length X in the horizontal direction of the virtual body IB is defined as "character width", and the length Y in the vertical direction is defined as "character height". Generally, as shown in FIG. 59 (a), the character width X
And the character height Y have the same value, that is, the virtual body IB has a square shape.

Inside the virtual body IB, a "character surface" F indicating the character shape of the character itself is arranged at an appropriate position. This character surface F is dot data consisting of a collection of points or a vector mathematically indicating the shape. It is composed of data.

Also, for font data whose virtual body IB is a square, as shown in FIG. 59 (b), the flatness rate hp (%) with the character height Y set to "100%" is designated. And the character height Y of the virtual body IB is (100-h
p)% compressed laterally long face F is formed, likewise
As shown in FIG. 59 (c), when the long body ratio lp (%) with the character width X set to "100%" is specified, the virtual body IB is specified.
The vertically long character face F in which the character width X of is compressed to (100-lp)% is formed.

In this specification, character data of one character having the above-defined structure is defined as font data unless otherwise specified. In this specification, basically, it is described that characters or modified characters are arranged as required, and it is described as "arrange characters" for the sake of easy understanding of the description. This is to "allocate data", and the description is changed as necessary.

What is needed as a reference when arranging the above character string is required. Here, the lower left of the virtual body IB is set as the reference point P.

That is, in the typesetting device, the font data of each character is output so as to be at the determined arrangement position with reference to the reference point P.

By the way, in recent years, for example, as seen in leaflets distributed by distributors, there is an increasing demand for transforming and arranging characters at the time of output in order to attract the viewer's attention. It is desired that the typesetting processing device be provided with the above function.

Conventionally, a typesetting device having a function of arranging a character in a plane such as arranging the character on an arc is gradually provided, but the character is deformed and arranged so as to have a visual depth ( In the following, there are few equipped with a function (simply referred to as “perspective arrangement”).

Therefore, in the conventional apparatus, when characters are to be arranged in the perspective as described above, the operator performs data processing for transformation processing for each font data, and edits while determining the arrangement position. It has to be done and it takes a lot of work.

Further, in the conventional typesetting device having the function of such a perspective arrangement processing, as shown in FIG. 60, each font data is transformed into a trapezoid as a figure so as to converge at a designated convergence point Q. I am letting you.

[0015]

However, the prior art having such a structure has the following problems. That is, in the character perspective processing performed by the conventional apparatus, the perspective is not displayed well because the characters are deformed as described above regardless of the character surface.

Further, in the conventional apparatus, since each font data is made into a graphic and integrally processed so as to have a designated perspective arrangement, it is not possible to flexibly deal with correction, insertion, deletion, etc. of characters. There is also.

For example, when "a" in FIG. 60 is corrected to "i", the font data Fd2 'corresponding to "i" is transformed as shown in FIG.
61 ", the font data Fd2 'is created with the same size and shape as shown in FIG. 61B.
Although it needs to be replaced with d2, new font data corresponding to the character to be corrected has to be created as a figure, which is complicated.

When the character "U" is inserted between "A" and "E" in FIG. 60, the font data Fd3 of "U" is replaced with the font data Fd4 as shown in FIG. 62 (a). It will be created with the same size and shape as, and will be inserted between "a" and "e" as shown in Fig. 62 (b). In this case, the size and shape of "e" and "o" The font data Fd in FIG.
5, it must be modified to the same size and shape as Fd6,
The processing becomes more complicated.

Further, when "a" is deleted in FIG. 60, the sizes and shapes of "o" and "e" are displaced as shown in FIG.
4, the size and shape of Fd5 must be corrected, and the process is complicated.

On the other hand, when the characters are modified and inserted or deleted after the characters are deformed and placed in perspective, the original character string can be corrected to a desired character string and the process can be restarted from the beginning. However, it is still inefficient to restart the process from the beginning.

The present invention has been made in view of the above circumstances, and it is possible to flexibly deal with correction, insertion, deletion, etc. of font data after the placement by performing natural perspective placement based on the character plane. An object of the present invention is to provide a typesetting processing device capable of performing the above.

And a color density specifying unit for obtaining a color density, wherein the output unit outputs each font data corresponding to each character in the text data with each color density specified by the color density specifying unit. It is a thing.

[0025]

The operation of the invention described in claim 1 is as follows. First, from the setting means, the arrangement start points P _S1 and P _S2 of the text data and the font data corresponding to the first character in the text data in the output area, and the font data corresponding to each character forming the text data are set. Is set to a perspective point in the output area, a convergence point Pe in the output area is set.

Next, the character arrangement processing control means first sets the arrangement start points P _S1 and P _S2 set by the setting means to the arrangement start points Pa and Pb of the font data corresponding to the first character in the text data. To the dimension specifying means to obtain the dimension of the font data corresponding to the first character in the text data, and to correspond to the first character based on the obtained dimension of the first character and the placement start points P _S1 and P _S2. The arrangement start point P _S1 , P _S2 and the data regarding the size of the first character are given to the arrangement start point specifying means, and the arrangement start point P of the second character in the text data is obtained.
Find a and Pb.

The dimension specifying means obtains the dimension of rectangular font data in which a line segment connecting the given placement start points Pa and Pb is one side of the virtual body.

Further, the arrangement start point specifying means is arranged so that the font data to be output is arranged along the line segment connecting P _S1 and Pe and the line segment connecting P _S2 and Pe. Arrangement start points Pa and Pb of the font data to be arranged next to the font data having the specified dimensions are obtained.

The character arrangement processing control means then gives the arrangement start points Pa and Pb of the second character obtained above to the dimension specifying means to obtain the size of the font data corresponding to the second character, The layout position of the font data corresponding to the second character is calculated based on the calculated second character size and the layout start points Pa and Pb when the second character size is calculated. Placement start point P when the dimension of
a, Pb and data concerning the dimensions of the second character are given to the arrangement start point specifying means, and the processing for obtaining the arrangement start points Pa, Pb of the third character in the text data is repeated, and for each character in the text data. The size of each corresponding font data and its layout position are sequentially obtained.

It is output based on the size and the arrangement position of each font data obtained by the processing control means.

The output result is such that the rectangular font data is gradually reduced along the line segment connecting P _S1 and Pe and the line segment connecting P _S2 and Pe, that is, the text data is converted. The font data corresponding to each of the constituent characters are arranged in perspective so as to have a visual depth.

In other words, according to the present invention, since each font data to be output is a rectangle without converting each font data into a graphic, natural perspective arrangement based on the character surface is possible.

Furthermore, each font data is required to have its respective dimensions and layout positions so that it can be arranged in a perspective view, and the font data is output using a character code. Therefore, when modifying the font data,
By correcting the character code of the character corresponding to the font data to be corrected and outputting the font data, the font data corresponding to the corrected character is output in the dimension and arrangement position before the correction. Also, insertion and deletion of font data can be handled by shifting the character code of the character corresponding to the font data and re-outputting the font data. Therefore, it is possible to flexibly deal with correction, insertion, deletion, etc. of the photo data with respect to the output result.

The operation of the invention described in claim 2 is as follows. The rotation processing means outputs a line segment connecting the set placement start points P _S1 and P _S2 to the output area (xy coordinate system).
The converging point Pe and the point P _S2 (or the point P _S1 ) are rotated by a predetermined angle about the point P _S1 (or the point P _S2 ) so as to be parallel or coincident with the coordinate axis (x-axis or y-axis) of. The coordinates of the point Pe 'and the point P _S2 ' (or the point P _S1 ') are obtained.

In the dimension specifying means, the arrangement start point specifying means, and the character arrangement processing control means, the set convergence point Pe and point P _{S2 are set.}
(Or point P _S1 ) as the point Pe ′ and the point P _S2 ′ (or point P _S1 ′) obtained by the rotation processing means, the size of each font data corresponding to each character in the text data, and the arrangement position thereof. Ask for. At this time, since the point P _S1 (or the point P _S2 ) and the point P _S2 '(or the point P _S1 ') are parallel or coincident with the x-axis or the y-axis of the xy Cartesian coordinate system, each font It becomes easy to calculate the data size and layout position. However, the obtained arrangement position of each font data is the point P.
_S1 (or point P _S2 ) and point Pe 'and point P _S2 ' (or point P
_S1 ') and against.

Therefore, the reverse rotation processing means determines the obtained point P _S1.
(Or point P _S2 ), point Pe ′, and point P _S2 ′ (or point P _S1 ′)
Point Pe 'and point P _S2 ' (or point P _S1 ') by the rotation processing means
The font position read out from the font is read out by the output means by finding the placement position of each font data with respect to the set placement start points P _S1 , P _S2 and the convergence point Pe by performing the reverse rotation by the rotation angle when The data is output based on the arrangement position of each font data and the obtained size with respect to the set arrangement start points P _S1 and P _S2 and the convergence point Pe. As a result, from the set placement start positions P _S1 and P _S2 to the convergence point Pe
Each font data is output in a perspective arrangement so as to converge to.

The operation of the invention described in claim 3 is as follows. From the color density setting means, the color density (start color density) of the font data corresponding to the first character of the given text data and the color density (end color density) of the font data corresponding to the last character of the text data are given. Is set.

The color density specifying means calculates the color density of each font data so that the color density of each font data corresponding to each character gradually (linearly) changes from the start color density to the end color density. .

The output means reads each font data corresponding to each character in the text data from the font registered in advance using the character code of each character, and the read font data is obtained with the obtained size and arrangement. Output is performed based on the position and each color density specified by the color density specifying means.

The data (auxiliary data) necessary for the process of inserting a new character is stored, and both data are also stored in the external storage device 18 such as a magnetic disk device. This is because the formatted character string is stored in the memory so that it can be output as needed based on the data.

The font data registered in advance in the font storage unit 13 is read out based on the data created by the display device 14
Or printed by the printer 15 or printed on the film by an output scanner (not shown).

A control unit 16 in the figure controls the entire apparatus. For example, when the control unit 16 controls the input control unit 11 to store the text data and the typesetting instruction in the buffers 2 and 3, the character arrangement processing unit 1 is instructed to start the character arrangement calculation process. When the character arrangement processing unit 1 notifies that the predetermined data has been created in the typesetting data table 7 and the typesetting auxiliary data table 8, the output control unit 1
2 is controlled to output the formatted result.

The memory 17 includes data necessary for processing stored in advance in the external storage device 18, the character arrangement processing section 1, the dimension specifying section 4, the arrangement start point specifying section 5, the color density specifying section 6, and the input control section.

Further, the output control unit 12, the display device 14, and the printer 15 correspond to the output means in the present invention.

Next, the processing procedure in the perspective arrangement typesetting of character strings of the apparatus of this embodiment will be described with reference to the flowcharts of FIGS. FIG. 2 is a main flowchart showing the processing procedure.

In FIG. 2, first, text data is taken in (step S1). That is, when the operator specifies the data file of the character string to be processed by the input unit 9, the input control unit 11 sequentially stores the character code of each character in the text data buffer 2.

FIG. 6 shows the content / structure of the text data stored in the text data buffer 2 by taking the character string "large bargain" as an example. In the following, the following description will be given by taking "large bargain" as an example of the character string.

Returning to FIG. 2, the processing procedure for fetching the typesetting instruction (step S2) will be described with reference to FIG.

Here, basic instruction elements for the perspective arrangement will be described with reference to FIG. 9 (a) to 9 (d) show how the characters are transformed and arranged so that "large" in the character string "large bargain" is closest and "n" is farthest away. As shown in the figure, it is necessary to specify or confirm the closest character arrangement and the farthest character arrangement for perspective arrangement. In the following, each character is simply referred to as "most recent character" or "farthest character". In the present invention, for the most recent character arrangement, the two points (P _S1 , P _S2 ) in front of the font data of that character are used.
And for the arrangement of the farthest character, the convergence point P seen from perspective.
Basically, the character string is deformed and arranged along a triangle connecting these three points by designating e.

First, the arrangement start points P _S1 and P _S when outputting the font data corresponding to the first character of the text data
When arranging each coordinate in the user space of _S2 (corresponding to the output area that is actually typeset in the coordinates (xy coordinates) on the computer processing area such as plain memory) and each character that constitutes the text data in the perspective position The coordinates of the convergence point Pe of are captured (step S11).

That is, as shown in FIG. 7A, the point P
Each (x, y) coordinate of _S1 , point P _S2 , and point Pe is designated. The origin (0, 0) of the xy Cartesian coordinate system is the display device 1.
4 corresponds to a predetermined point in the display space, and a predetermined point in a region for typesetting output by printing or film printing.

When the user sets the coordinates of each point from the input unit 9, the input control unit 11 changes the coordinates to
It is stored in a predetermined area of the typesetting instruction buffer 3.

Here, the structure of the typesetting instruction buffer 3 is shown in FIG.
Shown in As shown in FIG. 8, in the typesetting instruction buffer 3,
In addition to the (x, y) coordinates of the designated points P _S1 , P _S2 , and Pe, an area is provided for storing a set direction instruction, a long flat body ratio, a start color density, and an end color density, which will be described later.

By the way, in order to transform and arrange the character string to be processed, the points P _S1 and P _S2 converge to the point Pe, in other words, the points P _S1 , _Ps2 and Pe form a triangle. Must be set to The positional relationship between these three points is, for example, as shown in FIGS.
There are various forms (d) and (e), but basically the point P
_{Since the} point Pe is not located on the line (linear function) including the line connecting the _S1 and P _S2 (the straight line P _S1 −P _S2 ), the above condition can be examined.

As shown in FIG. 7 (a), the coordinates of each point are point P _S1 (x _s1 , y _s1 ), point P _S2 (x _s2 , y _s2 =
y _s1 ), and point Pe (x _e , y _e ), where point P _S1
The following description will be made assuming that the line segment SL connecting the point P _S2 and the point P _S2 is set parallel to the x-axis (the y coordinates of the point P _S1 and the point P _S2 are the same).

In the following, the processing method for obtaining the arrangement position of each character for the perspective arrangement will be referred to as "processing pattern 1" below.

Returning to FIG. 3, next, a set direction instruction is fetched (step S12). The typesetting instruction is an instruction for designating horizontal typesetting or vertical typesetting. If horizontal writing is specified, points P _S1 , _Ps2 , and Pe
9 (a) and 9 (b) according to the positional relationship with
Typesetting is performed as shown in (d).

When the user specifies a code indicating a set direction instruction from the input section 9 (for example, "0" means horizontal setting and "1" means vertical setting), the input control section 11 specifies it. The code is stored in the <typesetting direction> area of the typesetting instruction buffer 3 (see FIG. 8).

Returning to FIG. 3, next, the long flat rate is taken in (step S13). The user sets the long body ratio or the flat body ratio from the input unit 9 according to the shape of the typeset characters. When specifying the long body ratio, lp (%) in FIG. 59 (c) is specified, and when specifying the flat body ratio,
The hp (%) in FIG. 59B is designated and stored in the areas of <long body ratio> and <flat body ratio> of the typesetting instruction buffer 3, respectively. Note that only one of the long body ratio and the flat body ratio can be specified. If neither is specified, both the long body ratio and the flat body ratio are “0”.

Returning to FIG. 3, next, the color density (start color density) of the first character and the color density (end color density) of the last character of the target character string are fetched (step S14). The start color density and the end color density set by the user from the input unit 9 are stored in the <start color density> and <end color density> areas of the typesetting instruction buffer 3, respectively.

The start color density and the end color density data are R (red), G (green), and B (blue) color densities (for example, the color densities depending on the output device of the typesetting result, such as a color display device and a printer). ,% To the maximum concentration of 100) or Y
(Yellow), M (magenta), C (cyan), and K (black) are designated by the color densities (halftone dots, etc.)
As shown by the starting color density in FIG. 10, an area for storing each color density is secured.

Further, since the RGB and YMCK color densities can be converted (not described in detail because they are known techniques), only one may be designated and the other may be calculated.

Returning to FIG. 2, next, the size, arrangement position, and color density of each font data are obtained, and the formatted data table 7
Pre-processing for editing is performed (step S3).

Here, FIG. 11 shows an example of the structure of the formatted data table 7 and this character string. The typesetting data table 7 includes a header part HA and a character processing data part FAn of each font data corresponding to each character forming the text data.
(N is the number of characters in the target character string). The header portion HA includes <assembly direction>, <long body ratio>, <flat body ratio>, <
The rotation angle θ>, <number of characters>, and <number of processed characters> are included in the data area. The character processing data unit FAn includes a <character code>, a <arrangement position x>, and a <arrangement position y for each character.
>, <Dimension>, <color density> data area.

In this preprocessing, first, the character arrangement processing unit 1
However, the character code of each character is stored from the text data buffer 2, and each data of the setting direction, length ratio, flatness ratio, start color density, and end color density is stored in the typesetting data table 7 from the typesetting instruction buffer 3. .

The start color density and the end color density are stored in the character processing data section (the color density data areas FA1 and FA5 in this example) corresponding to the first and last characters, respectively. Further, the <color density> of the character processing data portion FAn is similar to that of the typesetting instruction buffer 3, and Y, M, C, K and R,
The color densities of G and B are stored.

Then, the "large bargain" character code is stored in each <character code> area of the character processing data portion FAn of the typesetting data table 7. At this time, the count value of the number of characters of the text data (“5” in this embodiment) is set in the <character number> area, and the rotation angle of the font data at the time of output is set in the <rotation angle θ> area. As a result, as shown in FIG. 12, the font data is output after being rotated by θ about the reference point P of the virtual body IB with respect to the x axis of the xy orthogonal coordinate system.

Although part of FIG. 9 has been described above, the specific points Pe, P _S1 , P _S2 and the character string of "Large Burn" are vertically assembled in (c) and (d), respectively (a), ( In FIG. 9B, a rotation angle is θ = + 90 in FIG. 9A, and θ = −90 (or +270 in FIG. 9B). ), FIG. 9 (c),
In (d), θ = 0.

Further, the character arrangement processing unit 1 stores P _S1 stored in the typesetting instruction buffer 3 in the typesetting auxiliary data table 8 shown in FIG. 13 and the work area 21 shown in FIG. 14 provided in the memory 17, respectively. Each of P _S2 and Pe (x, y)
The coordinates are stored in the corresponding areas as shown. Also,
<Pax x and y coordinates>, <Pb of work area 21
In the area of x-coordinate, y-coordinate>, the (x, y) coordinates of the points P _S1 and P _S2 are stored as initial values. The typesetting auxiliary data table 8 is a table used when inserting another character.
The work area 21 is also used as a work area for obtaining the color density and the like. The insertion process will be described later.

Next, the start color density (Y _S , M _S , C in halftone%)
_S , K _S ) and end color density (halftone% Y _E , M _E , C
_E , K _E ) based on each data, the rate of change of color density (α _Y , α _M , α _C , α) for determining the color density of each character
_K ). The change rate is (start color density-end color density)
/ (Number of characters-1) In the case of the present embodiment, since the number of characters is "5", it is as follows. α _Y = (M _E −M _S ) / 4 α _M = (M _E −M _S ) / 4 α _C = (C _E −C _S ) / 4 α _K = (K _E −K _S ) / 4 α _R = (R _E −R _S ) / 4 α _G = (G _E −G _S ) / 4 α _B = (B _E −B _S ) / 4 where α _R , α _G , and α _B are RGB color densities. Of the YMCK and RGB, and can be selected and adopted by any of them. These are shown in each graph of FIG. Each obtained change rate data is stored in the typesetting auxiliary data table 8.

Returning to FIG. 2, when the preprocessing is completed, next,
The size, arrangement position, and color density of each font data corresponding to each character forming the text data are obtained (step S
4). A specific processing procedure will be described with reference to the flowchart shown in FIG.

First, the processing variable i is set to "1" (step S21). Next, the i-th character (here i = 1
Then, the output dimension of the first character "large" is obtained (step S22).

This will be described with reference to FIGS. 16 and 17. Note that FIG. 16 is similar to FIG. 1 in the case of FIGS.
7 shows the cases of FIGS. 9 (d) and 9 (b), respectively. Further, Pa, Pb, Pc, and Pd are points used each time the font data is transformed and arranged for each character, and each point is associated with each corner as shown in FIGS. 16 and 17. For the coordinates of the points Pa and Pb, the values stored in the area of (x, y) coordinates of Pa and Pb of the work area 21 are used, and the first character is Pa = P _S1 and Pb = P _S2 ( It was set as an initial value in the preprocessing), and Pa and P of the second and subsequent characters
b is specified in step S31 (described later) in the previous character, and Pa of the work area 21 and (x, y) of Pb.
The stored contents of the coordinate area are updated.

16 (a) and 16 (b), font data of a square virtual body IB in which neither the long body ratio nor the flat body ratio is specified are arranged vertically and horizontally, respectively. In this case, the font data dimensions are Pa and Pb.
The length is between. Pa, the length L between Pb, the coordinates of _{Pa (x a, y a)} , the coordinates of Pb (x _b, y _a) When, because character base is parallel to the x-axis, the following formula Can be calculated by _{L = X = | x b -x} a | ......... (22-1)

16 (c) and 17 (c) show the flatness ratio (hp
When the font data for which%) is specified is arranged vertically, the character height is Y '(= Y × (100-hp) / 10
The font data compressed in 0) is arranged at a predetermined arrangement position. The size of the font data in this case is as shown in the previous formula (22-1).
Is the same value as L.

16 (d) and 17 (d) show the long body ratio (lp
When the font data for which%) is specified is arranged horizontally, and the character width is X '(= X × (100-lp) / 10
The font data compressed in 0) is arranged at a predetermined arrangement position. The size of the font data in this case can also be calculated using the formula (22-
It is the same L as in 1).

16 (e) and 17 (e) show the long body ratio (lp
%) When arranging the font data specified by vertical composition in vertical composition, the font data compressed to a character width of X '(X' is obtained from the X coordinate of Pa and Pb) is arranged at a predetermined arrangement position. To do. Therefore, X corresponding to the size of the original font data can be obtained by the following formula. X = (100 ・ X ') / (100-lp) ……… (22-2)

FIGS. 16 and 17 (f) show the flatness ratio (hp
%) When arranging the font data specified by horizontal writing mode, the font data compressed to a character height of Y '(Y' is obtained from the X coordinate of Pa and Pb) is placed at a predetermined position. Deploy. Therefore, Y corresponding to the size of the original font data can be obtained by the following formula. Y = (100 · Y ') / (100-hp) ……… (22-3)

The size of the font data in each specified composition thus obtained is the composition data table 7 (see FIG. 11).
Of the character processing data section FAi corresponding to the i-th character of
Store in the dimension> area.

Returning to FIG. 4, next, it is judged whether or not the obtained size of the font data is less than 1 mm (step S2).
3) If it is less than 1 mm, proceed to the error processing of step S24, while if it is 1 mm or more, proceed to step S25.
This is because it is difficult to see the character surface when the size of the output font data is less than 1 mm.

In the error processing of step S24, first,
For example, by displaying an error message on the display device 14,
Notify the user that the error has ended, and check whether there is an error in the typesetting auxiliary data table 8 (see FIG. 13)
A code (for example, "1") indicating that the dimension is less than 1 mm and ended in error is stored in the area of, and the processing of FIG. 4 is ended.

As a cause of such an inconvenience, for example, the positional relationship between the designated three points P _S1 , P _S2 , and Pe with respect to the number of characters of the text data is inappropriate (for example, as shown in FIG. 18). And the length between the points P _S1 and P _S2 is longer than the length between the points P _S1 and Pe, the length between the points P _S2 and Pe, etc.), the points P _S1 , P _S2 , A message for resetting Pe may be added to the error message. Next, (i-1) is converted into the formatted data table 7 (see FIG.
1)) in the <number of processed characters> area. This <number of processed characters> is the number of characters corresponding to the font data in which all the dimensions, arrangement positions, and color densities are edited, and in the current i-th processing, the number of processed characters is (i-1).
Is.

Returning to FIG. 4, in step S25, the remaining two points Pc and Pd when the characters are arranged in step S24.
Find the coordinates of. At this time, as shown in FIGS. 16 and 17, the arrangement state of the font data at the time of output differs depending on the positional relationship between the points P _S1 , P _S2 , and Pe.

First, FIG. 16 shows a case where the position of the convergence point Pe is designated above the placement start points P _S1 and P _S2 . In this case, the points Pc in FIGS.
The x-coordinates x _c and x _d of Pd are respectively x _c = x _a x _d = x _b (25-1), as is clear from the figure.

Also, the y-coordinates y _c and y _{d of the} points Pc and Pd, respectively.
16A, 16E, 16B and 16F, and
16C and FIG. 16D are different.

In the case of FIGS. 16A and 16E, points Pc and P
The y-coordinate of d is obtained by adding the character height Y (= L) to the y-coordinates of the arrangement start points Pa and Pb, respectively. Therefore, _{y c = y d = y a} + L ......... (25-2).

In the case of FIGS. 16B and 16F, points Pc and P
The y coordinate of d is obtained by adding the character width X (= L) to the y coordinates of the arrangement start points Pa and Pb, respectively. Therefore, in this case, the y-coordinates y _c and y _d of the points Pc and Pd are finally obtained by the above equation (25-2).

In the case of FIG. 16C, the y-coordinates of the points Pc and Pd are the y-coordinates of the arrangement start points Pa and Pb, respectively, plus the character height Y ′ compressed by the flatness rate hp. .
Therefore, this case is the _{+ y c = y d = y} a (L × (100-hp) / 100)) ......... (25-3).

In the case of FIG. 16D, the y-coordinates of the points Pc and Pd are the y-coordinates of the arrangement start points Pa and Pb, respectively, plus the character width X'compressed by the length ratio lp. Therefore, in this _{case, y c = y d = y} a + (L × (100-lp) / 100) is ......... (25-4).

Next, FIG. 17 shows a case where the position of the convergence point Pe is specified below the arrangement start points P _S1 and P _S2 , contrary to the case of FIG.

Therefore, FIG. 17 is obtained by reversing the positive direction of the y-axis of FIG. 16, and the x-coordinates x _c and x _d of the points Pc and Pd in FIGS. It is calculated by the equation (25-1). 17 (a), (b), (e),
Point Pc in (f), FIG. 17 (c), and FIG. 17 (d),
The y-coordinates y _c and y _d of Pd are expressed by the above equation (25-2) and the above equation (25-3).
And in the above equation (25-4), "+" can be replaced with "-".

As described above, the size of the i-th character is Pa, P
It is arranged in a rectangle defined by b, Pc, Pd, and the next character is similarly arranged by Pa, Pb, Pc, Pd newly obtained for the next character by this rectangle and the convergence point Pe. These points will be described later. The layout position at the time of typesetting output is determined by the position of the reference point P, and the reference point P is determined by the designated P _S1 , P _S2 , Pe and the assembly direction (step S26).

That is, in FIGS. 16 (a), 16 (c), and 16 (e), which are vertically assembled with y _S1 and y _S2 <y _e , the reference point P of the font data is the point Pa, and the arrangement position is the coordinates of the point Pa. Becomes

In addition, FIG. 1 in the horizontal composition with y _S1 and y _S2 <y _e
In 6 (b), (c), and (f), the reference point P of the font data is the point Pb, and the arrangement position is the coordinates of the point Pb.

Furthermore, in y _S1 and y _S2 > y _e vertically assembled in FIGS. 17A, 17C, and 17E, the reference point P of the font data is the point Pc, and the arrangement position is the coordinates of the point Pc. Becomes

In addition, FIG. 1 in horizontal writing mode with y _S1 and y _S2 > y _e
7 (b), (c), and (f), the reference point P of the font data is the point Pa, and the arrangement position is the coordinates of the point Pa.

The character arrangement processing unit 1 uses the (x, y) coordinates of the reference point P obtained as described above in the <arrangement position x> and <arrangement position y of the i-th character processing data portion FAi of the typesetting data table 7. ＞ area.

Returning to FIG. 4, next, the color density of the font data corresponding to the current character to be processed is obtained (step S27). The character arrangement processing unit 1 supplies the processing variable i to the color density specifying unit 6 so that the color density specifying unit 6 determines the order of the given characters and the change rate of the color density obtained in the preprocessing. Based on this, the color density of each character is obtained.

As is apparent from FIG. 19, when the color density of the i-th character is Y _Ni , the change rate α of the color density obtained in advance is
_{It is calculated from Y} and the starting color density Y _S by the following formula. Y _Ni = Y _X + Y _S = α _Y × (i-1) + Y _S

Note that Y _X3 in the figure is the third character (i =
3) "-" indicates the amount of change in color density from the starting color density Y _S , and Y _N3 indicates the color density of the character.

When i = 1 (first character) or i = the number of characters in the text data (last character),
Since the color density of each character is the start color density and the end color density itself, the above calculation is unnecessary.

In the figure, the values in parentheses are Y _S = 40, Y _E
= 60, the color density of each character is shown.
It can be seen that the starting color density gradually changes to the ending color density. The change rate α _Y of the color density at this time is (60−
40) / 4 = 5.

Incidentally, other M, C, K net%, R,
Regarding the color densities of G and B, the color densities of the current character to be processed can be calculated in the same manner as in the case of the Y dot%.

The color density specifying unit 6 returns the obtained color density to the character arrangement processing unit 1, and the character arrangement processing unit 1 sets the received color density in the i-th character processing data unit FAi of the typesetting data table 7 < Color density> area is stored.

Returning to FIG. 4, next, the arrangement start point specifying unit 5
Is a line segment connecting point P _S1 and point Pe and point P _S2 and point Pe
The intersection of the line segment connecting the and the virtual body in the virtual arrangement state of the current character to be processed is obtained (step S2).
8).

The pattern in which this intersection exists is shown in FIG.
This is the case shown in each of FIG. Specifically, (1) an intersection of a line segment connecting the point P _S1 and the point Pe and a line segment connecting the point Pc and the point Pd (2) a line segment connecting the point P _S1 and the point Pe, Intersection point with line segment connecting point Pb and point Pd (3) Intersection point with line segment connecting point P _S2 and point Pe and line segment connecting point Pa and point Pc (4) point P _S2 and point It is investigated whether or not there is an intersection between the line segment connecting Pe and the line segment connecting the points Pc and Pd.

Point P _S1 (coordinates (x _S1 , y _S1 )) and point Pe
A linear function including a line segment CL1 connecting (coordinates (x _e , y _e )) is [y = a ₁ · x + b ₁ ], point P _S2 (coordinates (x _S2 ,
The linear function including the line segment CL2 connecting y _s2 )) and the point Pe is defined as [y = a ₂ · x + b ₂ ]. As shown in FIG. 22,
a ₁ and a ₂ represent the slope of each function, and b ₁ and b ₂ represent the position of the intersection of each function with the y axis. Since each method of calculation is mathematically easy, it is omitted.

Therefore, a linear function including the line segment CL1 connecting the point P _S1 and the point Pe and a linear function including the line segment CL2 connecting the point P _S2 and the point Pe, the point Pa and the point Pb, By using the positional relationship between the points Pc and Pd, the above (1) to (4) can be examined. However, when the x-coordinates of the point P _S1 and the point Pe are the same (x _S1 = x _e ), x = x _S1 , and in this case, as shown in FIGS. 20 (f) and 21 (f). And point P
_The line segment CL1 connecting _S1 and the point Pe coincides with the line segment connecting the point Pa and the point Pc, the intersection with the virtual body of the font data is the point Pc, and the point P _S2 and the point Pe are x. When the coordinates are the same (x _S2 = x _e ), x = x _S2 , and in this case, as shown in FIGS. 20 (d) and 21 (d),
The line segment CL2 connecting the point P _S2 and the point Pe is the point Pb and the point Pd.
The point Pd coincides with the line segment connecting the and, and the intersection with the virtual body of the font data is the point Pd. Therefore, x between the point P _S1 and the point Pe
When the coordinates are the same, the intersection is set as the point Pc
If (1) and (2) are omitted and the x coordinate of the point P _S2 and the point Pe are the same, the intersection point is taken as the point Pd and the above (3) and (4) are omitted.

First, in (1), as shown in FIGS. 23 (a) and 23 (b), 1 including the line segment CL1 connecting the point P _S1 and the point Pe.
In the next function [y = a ₁ · x + b ₁ ], y of points Pc and Pd
The x coordinate (x = (y _c −b) when the coordinate (y _c ) is substituted.
₁ ) / a ₁ ) is the x coordinate (x _a ) of the point Pc and the x of the point Pd.
If they are within the range between the coordinates (x _b ), these intersections exist.

The point of intersection CP ₁ is found in this case (1) in the cases of (b) to (e) of FIGS. 20 and 21. Further, a the (1) at the intersection of the intersection CP ₁ when CP ₁ is present x-coordinate is the _{x (= (y c -b 1} ) / a 1), the intersection point C
The y coordinate of P ₁ is the y coordinate (y _c ) of the point Pc and the point Pd.

Next, in (2), as shown in FIGS. 23 (c) and 23 (d), 1 including the line segment CL1 connecting the point P _S1 and the point Pe.
In the next function [y = a ₁ · x + b ₁ ], x of point Pb and point Pd
Y coordinate (y = a ₁ · x _b ) when the coordinate (x _b ) is substituted
+ B ₁₎ is, if within the range between the y-coordinate (y _a) and the y coordinate of the point Pd of the point Pb (y _c), so that these intersections are present.

The intersection can be found in this (2) as shown in FIG.
This is the case of (a) and (b) of FIG. Also, this (2)
In the case where the intersection point CP ₁ exists, the x coordinate of the intersection point CP ₁ is the x coordinate (x _b ) of the points Pb and Pd, and y of the intersection point CP ₁
The coordinates are y (= a ₁ · x _b + b ₁ ) described above.

Next, in (3), as shown in FIGS. 23 (e) and (f), the point P _S2 and the point Pe are processed by the same method as in the case of (2).
A linear function [y = a ₂ · x + b including a line segment CL2 connecting
₂ ], the y coordinate (y = a ₂ · x _a + b ₂ ) when the x coordinate (x _a ) of the point Pa and the point Pc is substituted is the y coordinate of the point Pa (y _a ) and the y coordinate of the point Pc. Whether or not there is an intersection is checked depending on whether or not it is within the range between the coordinates (y _c ).

The intersection can be found in (3) in FIG.
This is the case of (h) and (i) of FIG. Also, this (3)
In the case where the intersection point CP ₂ exists, the x coordinate of the intersection point CP ₂ is the x coordinate (x _a ) of the points Pa and Pc, and the y point of the intersection point CP ₂ is y.
The coordinates are the above y (= a ₂ · x _a + b ₂ ).

Next, in (4), as shown in FIGS. 23 (g) and (h), the point P _S2 and the point Pe are processed in the same manner as in the case of the above (1).
A linear function [y = a ₂ · x + b including a line segment CL2 connecting
_2], the point Pc, x coordinate when substituting the y coordinate of the point _{Pd (y c) (x =} (y c -b 2) / a 2) is, x-coordinate of the point Pc (x _a) and a point Whether or not there is an intersection is checked depending on whether or not it is within the range between the x coordinate (x _b ) of Pd.

The intersection can be found in (4) as shown in FIG.
The case of FIG. 21 (e) ~ (h), x-coordinate of the intersection point CP ₂ in the case where there are intersections CP ₂ in the (4) of the x
(= (Y _c −b ₂ ) / a ₂ ), and the y coordinate of the intersection point CP ₂ is the y coordinate (y _c ) of the point Pc and the point Pd.

Returning to FIG. 4, next, the intersection point CP ₁ or /
And whether there is CP ₂ (step S2)
9). If there is at least one of the intersection points CP ₁ and CP ₂ , the process proceeds to step S31. On the other hand, if there is no intersection, the arrangement start point specifying unit 5 notifies the character arrangement processing unit 1 that there is no intersection and ends the process. At this time, the character arrangement processing unit 1 executes the error processing of step S30.

In the error processing of step S30, an error message is displayed on the display device 14 to inform the user of the error end. Incidentally, as a cause of such an inconvenience, for example, in the case as shown in FIG. 24, at this time, a message for resetting the points P _S1 , P _S2 , and Pe may be added to the error message. . Further, the processing from step S28 is a processing for obtaining the arrangement start points Pa and Pb of the font data corresponding to the character next to the character currently being processed. Therefore, when the current processing target character is the last character of the text data, a message notifying that the insertion processing is impossible may be displayed. Next, i is stored in the <number of processed characters> area of the formatted data table 7. This is because the font data size, arrangement position, and color density corresponding to the i-th character are all edited. Further, a code (for example, "2") indicating that the process ends in error without an intersection is stored in the area of <presence of error> of the typesetting auxiliary data table 8.

Returning to FIG. 4, next, the above step S28.
Based on the intersections obtained in step S1, the placement start points Pa and Pb of the font data corresponding to the (i + 1) th character are determined (step S31). This processing is performed by the placement start point specifying unit 5,
The steps S28 and S29 are subsequently performed.

Specifically, a line parallel to the line segment connecting the obtained intersection points CP ₁ and / or CP ₂ and connecting the points P _S1 and P _S2 is obtained, and the line and the point P _S1 and the points are obtained. The intersection of the line segment connecting Pe and the line segment connecting the point P _S2 and the point Pe is determined. The obtained intersections are the placement start points Pa and Pb of the font data corresponding to the character ((i + 1) th character) next to the character currently being processed.

Here, since the line segment connecting the points P _S1 and P _S2 is parallel to the x axis (or on the x axis), it passes through the obtained intersection points CP ₁ and / or CP ₂ and the point P _S1 And point P _S2
The respective points of intersection of the line parallel to the line segment connecting the line P, the line segment connecting the point P _S1 and the point Pe, and the line segment connecting the point P _S2 and the point Pe are
It is the same as the y coordinate of the intersection points CP ₁ and CP ₂ .

FIG. 25 shows the positional relationship between Pa and Pb obtained according to the pattern having the intersections shown in FIG. Note that FIG. 25 shows the arrangement start points P and Pb of the font data corresponding to the second character. In addition, regarding the pattern having the intersections shown in FIG.
This is similar to the case of the pattern shown in FIG.

The layout start point specifying unit 5 returns the new layout start points Pa and Pb thus obtained to the character layout processing unit 1. The character placement processing unit 1 stores the received (x, y) coordinates of the new placement start points Pa and Pb in the work area 21, and sets the coordinates of the placement start points Pa and Pb to the (i + 1) th character. Update to the one for the corresponding font data.

Returning to FIG. 4, next, it is determined whether or not the dimensions, arrangement positions, and color densities have been obtained for all the characters that make up the text data (step S32). If the process has been completed for all characters, the process proceeds to the end process of step S34, while if the process has not been completed for all characters,
The process proceeds to step S33. The ending process of step S34 will be described later.

In step S33, the process variable i is incremented (i = i + 1) to set the character to be processed as the next character, and the process returns to step S22. Based on the newly obtained placement start points Pa and Pb, that character is selected. The size, arrangement position and color density of the corresponding font data are obtained in the same manner as described above.

For example, taking the second (i = 2) character "ba" as an example, first, at step S22, the arrangement start point Pa of the font data corresponding to the second character shown in FIG. 25, Based on Pb, the size of the font data corresponding to the second character is obtained according to the assembling direction, the long flat body ratio, etc. as shown in FIG. 16 (and FIG. 17).

Next, in step S25, the remaining two points Pc of the virtual body of the font data corresponding to the second character,
Pd is obtained, the arrangement position of the font data corresponding to the second character is determined from Pa, Pb, Pc, and Pd in step S26, and the color density of the font data corresponding to the second character is obtained in step S27.

Then, in steps S28 to S31, for example, as shown in FIG. 26 (FIG. 26 corresponds to FIGS. 20 and 25, (y coordinate of points P _S1 , P _S2 )> (point P
The same applies to the case of the y coordinate of e). ), The placement start points Pa and Pb of the font data corresponding to the next character (third character) are obtained, and the size, placement position, and color density of the font data corresponding to the third character are similarly determined. Ask. After that, in the same manner, when the processing is completed for all the characters, the process proceeds to the ending processing of step S34.

In step S34, the size, arrangement position, and color density of each font data corresponding to all the characters of the text data are obtained.
The number of characters of the text data (i indicating the last character) is stored in the area of processed character number>. Next, a code indicating normal completion (for example, "0") is stored in the <presence / absence of error> area of the typesetting auxiliary data table 8, <x coordinate of Pa at the time of insertion processing>, <the time of insertion processing> P
In the area of y coordinate of a>, <x coordinate of Pb during insertion processing>, <y coordinate of Pb during insertion processing>, the character next to the last character of the last obtained text data (current text data X) and y coordinates of the arrangement start points Pa and Pb (which do not exist in the above) are stored respectively. That is, at the normal end, in the typesetting auxiliary data table 8, the coordinates of the point P _S1 , the point P _S2 , and the point Pe, and the arrangement start points Pa and Pb of the character next to the last character of the current text data, Change rate of color density α _Y , α _M , α _C , α _K , α _R , α _G , α
_B will be stored, and by using these data, when a character is inserted in the current text data, the size, arrangement position, and color density of the font data corresponding to the inserted character will be displayed later. You can ask.

Returning to FIG. 2, when the processing for obtaining the size, arrangement position, and color density of each character of the text data is completed, the data stored in the typesetting data table 7 and the typesetting auxiliary data table 8 are externally stored. It is stored in the device 18 (step S5). This is so that the output etc. can be performed anytime thereafter based on the data edited this time.

Next, based on the contents of the formatted data table 7, the output control unit 12 outputs the processing result to the display device 14 and / or the printer 15 (step 6). In addition, it is displayed on the display device 14 or printed by the printer 15,
Whether the film is printed or both are arbitrarily selected by the user. Details of the output processing by the output control unit 12 will be described with reference to FIG.

First, it is determined whether or not the processed characters stored in the <number of processed characters> area of the formatted data table 7, that is, the number of characters that can be output is “0” (there is no font data that can be output). If it is not "0" (step S41), there is font data that can be output, so the process proceeds to step S42. On the other hand, if it is "0", there is no font data that can be output, and the process ends. It should be noted that when the processing is ended without outputting, a message notifying the user may be displayed on the display device 14.

In step S42, the processing variable i is "1".
Set. i is for indicating what character the current processing target is.

Next, the character code of the current processing target is read from the character processing data section FAi of the current processing target of the typesetting data table 7, and the font data is read from the font storing section 13 (step S43).

Next, from the character processing data portion FAi,
The size of the font data at the time of output is read, the font data read at step S42 is reduced to the size at the time of output, and the size is adjusted.
The set long body ratio and flat body ratio are read from the areas of long body ratio> and <flat body ratio>, and the font data whose size has been adjusted is adjusted according to the set long flat body ratio. Is compressed (step S44).

Next, from the areas of <arrangement position x>, <arrangement position y>, and <color density> of the character processing data portion FAi, the coordinates of the arrangement position (reference point of font data) at the time of outputting the font data. And the color density are read, the rotation angle θ is read from the <rotation angle θ> of the typesetting data table 7, and the font data whose dimensions and the like have been adjusted in step S43 is arranged at the layout position (reference point). The image is output with the read color density while being rotated by the rotation angle θ around (step S45).

For example, in the case of typesetting as shown in FIG. 9C, the rotation angle θ is “0 °”, so that the font data of which the dimensions and the like have been adjusted are arranged as shown in FIG. It Note that FIG. 27A shows the case where neither the long body ratio nor the flat body ratio is set, and FIG. 27B shows the arrangement state of each font data when the flat body ratio is set. FIG. 27C shows the arrangement state of each font data when the length ratio is set. FIG. 27 (b),
In (c), only the font data corresponding to "Large" is shown, but the character faces of each photo data corresponding to each character of "Bargain" are the same as "Large". Characters are compressed according to the rate.

Further, if the typesetting is performed as shown in FIG. 9A, the rotation angle θ is "90 °", so the first font data is shown by the chain double-dashed line in FIG. 28A. as such, from a state of arranging the font data on the position P _1, the rotation around the position P ₁ angle theta ( "90
.Degree. ") And is output while being rotated in a predetermined direction (counterclockwise because the sign of the rotation angle is positive in this case). Next, the second font data is as shown in FIG.
As indicated by the chain double-dashed line in (b), from the state where the font data is arranged at the arrangement position P ₂ , the font data is arranged counterclockwise by “90 °” about the arrangement position P ₂ and outputted. To be done. The arrangement position of the second font data is determined according to the arrangement state at the time of outputting the first font data, and thus the arrangement position is as shown in the figure.
The remaining font data is sequentially arranged and output in the same manner. FIG. 28 (c) shows the state after arrangement of all font data.
Shown in Note that FIGS. 28A to 28C show a case where neither the long body ratio nor the flat body ratio is set. FIG. 29A shows the arrangement state of the first font data and the arrangement state of the second font data when the flatness rate is set.
FIG. 29C and FIG. 29D show the arrangement state of the first font data and the arrangement state of the second font data when the length ratio is set in FIG.

27 and 28, the points P _S1 and
The positional relationship between P _S2, Pe is, the case of FIG. 20 (e), FIG. 20 (a) ~ (d) , (f) ~ (i), 2
Similarly, in each case of 1, each font data is point P.
It is arranged so as to converge from _S1 , P _S2 to the point Pe.

Also in the case of FIGS. 9B and 9D, FIG.
As in the case of, each font data is rotated from the state in which it is placed at each placement position to the rotation angle θ (“−90 °” in the case of FIG. 9B, and in the case of FIG. 9D). The output is arranged and rotated in a predetermined direction (clockwise because the sign of the rotation angle is negative in the case of FIG. 9B) by "0 °").

Returning to FIG. 5, it is judged whether or not all the outputable font data has been output (step S
46). If all the outputs have been completed, the processing of the apparatus of this embodiment is ended, while if there is font data that can be output, the processing variable i is incremented (i = i + 1).
Then (step S47), the process returns to step S43 to output the next font data.

When the processing of the apparatus of this embodiment is completed, each font data corresponding to each character forming the text data is displayed in a perspective arrangement so as to converge from the points P _S1 and P _S2 to the point Pe. Displayed on the device 14 and / or printed by the printer 15 and printed on film.

As described above, since the virtual body of each font data to be output is a rectangle, there is no character face of the font data to be output, and the natural font arrangement is used for typesetting based on the character face. Further, in the present embodiment, since each font data is not made into a figure, the process for making it into a figure is unnecessary.

Next, with respect to the above typesetting result, for example,
Set the font data corresponding to the first character "Large" to "Super"
A case where the font data corresponding to the character is corrected will be described. At this time, the size, arrangement position, and color density of the font data corresponding to “super” to be corrected may be the same as the size, arrangement position, and color density of the font data corresponding to “large”. It is only necessary to replace the "large" character code stored in the <character code> area of the character processing data portion FA1 of the first font data with the "super" character code. Based on the formatted data table 7 that has been re-edited in this way, if the data is output again in accordance with the processing procedure of FIG. 5, the font data corresponding to "Large" in the formatted result is corrected to font data corresponding to "super". Is output.

Next, a case will be described in which, for example, the font data corresponding to the third character "-" is deleted from the typesetting result for "large bargain". At this time,
The font data corresponding to the current 4th and 5th characters "ge" and "n" are set to the 3rd and 4th characters "-" and "
The font data corresponding to the character "" is arranged and output with the size, arrangement position, and color density, and the font data arranged at the arrangement position of the font data corresponding to the fifth character "N" is not output. Good.

Therefore, first, 3 of the formatted data table 7
In the <character code> area of the character processing data portion FA3 of the font data corresponding to the fourth character, the <character code> area of the character processing data portion FA4 of the font data corresponding to the fourth character is displayed.
Character code stored in the character code> area ("ge")
Character code) of the font data corresponding to the fourth character and the <character code> of the character processing data part FA5 of the font data corresponding to the fifth character is set in the <character code> area of the character processing data part FA4 of the font data. Set the character code (character code of "n") stored in the code> area.

Next, the header portion H of the formatted data table 7
The number of characters to be deleted (“1” in this case) is subtracted from the number of characters stored in the <character number> area of A. Then, the number of characters MM obtained as a result of the subtraction is compared with the number of processed characters SM stored in the <number of processed characters> area of the header portion HA of the formatted data table 7. The number of processed characters stored in the number of characters> area is M
Replace with M. This is adjusted so that the number of font data that can be output does not exceed the number of characters of the text data after deletion. Note that when MM = SM, all font data corresponding to the deleted character string is output in a perspective arrangement, and when MM> SM,
The font data corresponding to the characters after the deleted character string by the number of (MM-SM) characters are still not output. If the data is output again in accordance with the processing procedure of FIG. 5 based on the typesetting data table 7 thus edited again, the font data corresponding to a predetermined character is output in a deleted state.

It should be noted that when the output is performed by the above method, the output color density is, for example, Y halftone%, as shown in FIG.
As shown in (a), the color density of each font data is from the start color density to the color density of the font data corresponding to the last character after deletion, with the change rate α _Y of the color density obtained by the above process. It changes gradually. This is shown in FIG.
As shown in (b), the color density of the last character of the deleted character string is set to the set end color density, and for each font data corresponding to the deleted character string, from the start color density After the color density change rate α _Y 'of each font data is newly obtained by the method described in the process of step S3 of FIG. 2 so that the color density gradually changes to the end color density, the color density of each font data is calculated. You may ask again. At this time, the start color density and the end color density may be stored in the typesetting auxiliary data table 8, for example.

Next, for the typesetting result for "large bargain", for example, between the font data corresponding to the first character "large" and the font data corresponding to the second character "ba", "! A case of inserting font data corresponding to "" will be described. At this time, after the current last font data, the size, the layout position, and the like for outputting the font data for the number of characters to be inserted (in this case, "1"),
The color density is newly obtained, and the font data corresponding to the "!" To be inserted is output according to the size, arrangement position, and color density of the font data corresponding to the current second character "B". Fifth character "ba", "-", "ge", "n"
The font data corresponding to the current third to fifth characters "-", "ge", "n", the font data size, arrangement position, color density, and the newly obtained size,
It suffices to arrange and output the arrangement position and the color density, and output the font data to be output with the newly obtained dimension, arrangement position, and color density.

First, the typesetting auxiliary data table 8 (see FIG. 13).
Check the code stored in <Presence / absence of error> in (Refer to), and if there is an error in the previous typesetting process (if the code is other than “0”), to output the font data for the number of characters to be inserted. Since it is not possible to newly obtain the size, arrangement position and color density, a message notifying the user of that fact is displayed on the display device 14 and the character code is shifted. That is, the character processing data portion FAi (FA2) of the font data of the typesetting data table 7 for the font data (the second in this case) currently output at the position where the new font data is to be inserted-the number of processed characters (<processed (It is stored in the area of the number of characters>)
The character code stored in each <character code> area of the character processing data portion FAj of the font data corresponding to the th character is shifted backward by the number of characters to be inserted. Then, in the <character code> area of the character processing data portion FAi of the font data of the formatted data table 7 for the font data currently output at the position where the new font data is to be inserted, the character code corresponding to the font data to be inserted. Set. Based on the typesetting data table 7 that has been re-edited in this way, if the data is output again according to the processing procedure of FIG. 5, the typesetting result of the font data that can be output is output with the font data inserted. If the position of the font data to be inserted is after the font data that can be output, the result of the insertion will not be reflected, and therefore the above character shift need not be performed.

If the code stored in <presence / absence of error> of the typesetting auxiliary data table 8 is “0”, the size for outputting the font data after the font data of the current last character, Arrangement position and color density are newly obtained. That is, the coordinates of the points P _S1 , P _S2 , and Pe stored in the typesetting auxiliary data table 8 and the coordinates of the placement start points Pa and Pb of the font data next to the font data of the last character at the present, By using the change rate of the color density of each font data and following the same procedure as in FIG. 4, the size, the layout position, and the like for outputting the font data for the number of characters to be inserted after the font data of the current last character, Calculate the color density. If the number of font data to be inserted is large and the size of the font data for the number of characters to be inserted cannot be obtained, the following processing is performed up to the font data that can be output.

Next, <number of characters> in the formatted data table 7
The result of adding the number of characters to be inserted to the number of characters of the text data before insertion stored in the area is stored in the <number of characters> area of the formatted data table 7, and
The result of adding the number of newly outputable font data to the number of processed characters of the text data before insertion stored in the <number of processed characters> area of the formatted data table 7 is the formatted data table 7 <Number of processed characters>
Store in the area. Then, with respect to the character code stored in <character code> of the character processing data portion FAn of each font data of the typesetting data table 7, the same character code shift as described above is performed and the character code of the character to be inserted. Is set in the <character code> of the character processing data portion FAn of the predetermined font data. Based on the typesetting data table 7 re-edited in this way, if it is output again in accordance with the processing procedure of FIG. 5, each font data corresponding to the character string in which a predetermined character is inserted is obtained from the points P _S1 and P _S2. The data is output in a perspective arrangement so as to converge to the point Pe.

In the process of inserting the font data, similarly to the process of deleting the font data, from the start color density to the end color density for each font data corresponding to the inserted character string. You may comprise so that it may change gradually. At this time, the start color density and the end color density may be stored instead of the change rate of the color density of each font data stored in the typesetting auxiliary data table 8.

As described above, the correction, deletion, and insertion of the font data with respect to the typesetting result can be dealt with mainly by changing the character code, shifting, and the like. It is possible to flexibly deal with deletion and insertion.

The correction, deletion, and insertion processing of font data for this typesetting result can be performed in the same manner for the processing (processing patterns 2 and 3) described later and the following embodiments, and will be described later. In the process and in the examples below,
This description is omitted.

Next, in the above-mentioned first embodiment apparatus,
For example, as shown in FIG. 31, a line segment SL connecting the arrangement start points P _S1 and P _{S2 of} the font data corresponding to the first character
Will be described, when the size of each font data, the arrangement position, etc., are set in parallel with the y axis of the output area (or on the y axis). Note that this processing is called "processing pattern 2".

First, in step S1 of FIG. 2, text data (assuming that "large bargain" is input) and in step S2 (flowchart of FIG. 3) the font data arrangement start point P _S1 corresponding to the first character P _S2 , convergence point Pe,
A set direction instruction, a long flat body ratio, a start color density, and an end color density are set. The coordinates of the set point P _S1 , point P _S2 , and point Pe are (x _S1 , y _S1 ), (x _S2 , y _S2 ), and (x _e , y _e ) (see FIG. 31). However, x _S1 = x _S2 . FIG. 32 shows a pattern of arrangement of each font data at the time of output according to the setting method of the points P _S1 , P _S2 and the point Pe and the set direction instruction in this case. 32A and 32C are horizontal composition in the case of (x coordinate of point P _S1 , point P _S2 ) <(x coordinate of point Pe),
FIG. 32 shows the arrangement state of vertically set font data.
(B) and (d) show the arrangement state of horizontal and vertical font data in the case of (x coordinate of point P _S1 , point P _S2 )> (x coordinate of point Pe). The symbols P _{1 to} P ₅ in the figure are
The layout position (the lower left reference point of the virtual body of the font data) at the time of outputting each font data is shown.

Next, the preprocessing of step S3 in FIG. 2 is performed. This pre-processing differs from the above processing pattern 1 in that
It is the rotation angle θ of the font data at the time of output. As is clear from FIG. 32, in the case of this processing pattern 2, (x coordinate of point P _S1 , point P _S2 ) <(x coordinate of point Pe) and horizontal writing (in FIG. 32 (a)) When the rotation angle θ of the font data at the time of output becomes “0 °” and (x coordinate of point P _S1 , point P _S2 )> (x coordinate of point Pe) is in horizontal writing mode (FIG. 3).
2 (b)), the rotation angle θ of the font data at the time of output becomes “180 °” (or “−180 °”),
When (x coordinate of point P _S1 , point P _S2 ) <(x coordinate of point Pe) or (x coordinate of point P _S1 , point P _S2 )> (x coordinate of point Pe) is set vertically (FIG. 32 ( (c) and (d)), the rotation angle θ of the font data at the time of output becomes “−90 °” (or “270 °”).

Next, the processing for obtaining the size, arrangement position and color density of each font data in step S4 of FIG. 2 is executed. Here, steps S22, S25, S26, S28, and S31 (see FIG. 4) are different from the processing pattern 1 described above. These processes will be described below.

First, in the calculation of the size of the font data in step S22, the size specifying unit 4 receives the arrangement start points Pa and Pb of the font data received from the character arrangement processing unit 1 and corresponding to the current character to be processed. Based on this, the size of the font data is obtained as follows. When the line segment connecting the point P _S1 and the point P _S2 is set in parallel (or on the y axis) of the output area as in this processing pattern 2, the given arrangement start point Pa , Pb have the same x coordinate. Therefore, here, the given placement start point P
a, coordinates of Pb as _{(x a, y a),} (x a, y b), FIG. 33, with reference to FIG. 34, illustrating how to obtain dimensions.

FIGS. 33 (a), 33 (c) and 33 (e) are shown in FIG.
33 (b) and (b) correspond to the case (a), where the long flat body ratio is not set, the flat body ratio is set, and the long body ratio is set. d),
32F shows a case corresponding to FIG. 32C, showing a case where the long flat body ratio is not set, a case where the long body ratio is set, and a case where the flat body ratio is set. Also, FIG.
4 (a), (c), and (e) correspond to FIG. 32 (b), where the long flat body ratio is not set, the flat body ratio is set, and the long body ratio is set. Is set, and FIGS. 34 (b), (d), and (f) show FIG.
In the case corresponding to (d), the case where the long flat body ratio is not set, the case where the long body ratio is set, and the case where the flat body ratio is set are shown.

Character height Y and character width X in FIGS. 33 and 34.
Is the same as. Therefore, in FIGS. 33 and 34 (a),
In the cases of (b), (e), and (f), the size of the font data is the length between given Pa and Pb, as is clear from the figure. The length L between Pa and Pb can be calculated by the following formula. _{L = | y b -y a |} ......... (22-11)

Therefore, the dimension specifying unit 4 is provided with the configuration shown in FIGS.
In the case of (a), (b), (e), and (f) of
-11) L is returned to the character arrangement processing unit 1 as the size of the font data.

33 (c) shows the flatness ratio (hp
%), The length Y'compressed with the character height Y is Pa, Pb
The length is between. Therefore, the character height Y before the character height is compressed can be obtained by the following formula. 100: (100-hp) = Y: Y 'Y = (100.Y') / (100-hp) = (100.L) / (100-hp) ... (22-12) Here, L Is Pa, Pb calculated by the above equation (22-11).
The length is between.

Since the size of the font data in this case is the size of the font data of character height Y × character width X (= Y), the size specifying unit 4 determines the case of FIG. 33 and FIG. 34 (c). , The Y obtained by equation (22-12) is returned to the character arrangement processing unit 1 as the size of the font data.

33 (d) and FIG. 34 (d) show the length ratio (lp
%), The length X ′ obtained by compressing the character width X is the length between Pa and Pb. Therefore, the character width X before the character width is compressed can be obtained by the following formula. X = (100 * X ') / (100-lp) = (100 * L) / (100-lp) ... (22-13) Here, L is calculated | required by said Formula (22-11). Pa, Pb
The length is between.

Since the size of the font data in this case is the size of the font data of character width X × character height Y (= X), the size specifying unit 4 determines the case of FIG. 33 and FIG. 34 (d). , The X obtained by equation (22-13) is returned to the character arrangement processing unit 1 as the size of the font data.

Next, in the processing of step S25, the character arrangement processing unit 1 obtains the coordinates of the two points Pc and Pd other than the points Pa and Pb at the four corner points of the virtual body IB of the font data. How to obtain this will be described below with reference to FIGS. 33 and 34.

As is apparent from FIGS. 33 and 34, FIG.
3, the y-coordinates of the points Pc and Pd in each case of FIG. 34 are the same as the y-coordinates of the arrangement start points Pa and Pb, respectively.
That is, the y-coordinates y _c and y _d of the points Pc and Pd are obtained by the following equations. y _c = y _a y _d = y _b (25-11) where y _a and y _b are the y coordinates of the points Pa and Pb as described above.

Next, the respective x-coordinates x _c , x _{d of the} points Pc, Pd
The method of obtaining is described separately for each case of FIGS. 33 and 34.

First, FIGS. 33 (a), (b), (c),
In (d), the x-coordinates of the points Pc and Pd have the character width X or the character height Y at the x-coordinates of the arrangement start points Pa and Pb, respectively.
(X = Y) is added. Therefore, the x-coordinates x _c and x _d of the points Pc and Pd in this case are calculated by the following formulas. x _c = x _d = x _a + L (25-12) where x _a is the x coordinate of the points Pa and Pb as described above, and L is the size of the font data obtained in step S22. is there.

Further, FIGS. 34 (a), (b), (c),
In (d), the x-coordinates of the points Pc and Pd are the character width X or the character height Y from the x-coordinates of the arrangement start points Pa and Pb, respectively.
(X = Y) is subtracted. Therefore, the x-coordinates x _c and x _d of the points Pc and Pd in this case can be obtained by an equation in which “+” in the equation (25-12) is replaced with “−”.

Next, in the case of FIG. 33 (e), points Pc and Pd
The x-coordinate of is the sum of the x-coordinates of the placement start points Pa and Pb and the character width X ′ compressed by the length ratio lp. Therefore, in this case, the x-coordinates x _c and x _d of the points Pc and Pd are obtained by the following equations. x _c = x _d = x _a + (L × (100-lp) / 100)) ……… (25-13)

Further, in FIG. 34E, the x-coordinates of the points Pc and Pd are obtained by subtracting the character width X'compressed by the length ratio lp from the x-coordinates of the arrangement start points Pa and Pb, respectively. . Therefore, the x-coordinates x _c and x _d of the points Pc and Pd in this case can be obtained by an equation in which “+” in the equation (25-13) is replaced with “−”.

Next, in the case of FIG. 33 (f), points Pc and Pd
The x-coordinate of is the sum of the x-coordinates of the placement start points Pa and Pb and the character height Y ′ compressed by the flatness rate hp. Therefore, in this case, each x coordinate x of the points Pc and Pd
_c and _xd are _calculated by the following equations. x _c = x _d = x _a + (L × (100−hp) / 100)) ……… (25-14)

Further, in FIG. 34 (f), the x-coordinates of the points Pc and Pd are obtained by subtracting the character height Y ′ compressed by the flatness rate hp from the x-coordinates of the arrangement start points Pa and Pb, respectively. is there. Therefore, in this case, each x coordinate x of the points Pc and Pd
_c and _xd can be obtained by an equation in which "+" is replaced with "-" in the equation (25-14).

Next, in step S26, the character arrangement processing unit 1 arranges the font data from the points Pa, Pb, Pc, Pd based on the positional relationship of the points P _S1 , P _S2 , Pe and the set direction. Determine the position (reference point of virtual body).

As is apparent from FIGS. 33 and 34, the point Pb is located at the lower left of the virtual body IB in FIGS. 33 (a), 33 (c) and 33 (e), and FIGS. 33 (b) and 33 (d). ,
In (f), FIGS. 34 (a), (c), and (e), the point Pa is at the lower left of the virtual body IB, and FIGS. 34 (b), (d),
In (f), the point Pc is at the lower left of the virtual body IB.

Therefore, (x coordinate of P _S1 , P _S2 ) <(Pe
In horizontal writing mode, the arrangement position becomes the coordinate of the point Pb, and (x coordinate of P _S1 , P _S2 ) <(x of Pe)
(Vertical coordinates) and (x coordinate of P _S1 , P _S2 )> (P
In the horizontal writing mode (x coordinate of e), the arrangement position becomes the coordinate of the point Pa, and further, (x coordinate of P _S1 , P _S2 )> (Pe
(X coordinate) of the vertical position, the arrangement position is the coordinate of the point Pc.

[0189] Next, in step S28, the arrangement start point specifying unit 5, a point P _S1, the point P _S2, the point Pe, the point Pa, the point Pb,
A line segment connecting the point P _S1 and the point Pe and the point P _S2 and the point when the font data corresponding to the current character to be processed is virtually arranged in the output state based on the points Pc and Pd. The intersection of the line segment connecting Pe and the virtual body of the font data corresponding to the current character to be processed is obtained. The method of obtaining the intersection in the case of this processing pattern 2 will be described below.

Also in this case, the intersection of the line segment connecting the point P _S1 and the point Pe and the line segment connecting the point P _S2 and the point Pe with the virtual body IB of the font data corresponding to the current character to be processed is determined. As in the case of the processing pattern 1, only the following cases (1) to (4) exist.

(1) A line segment connecting the point P _S1 and the point Pe and the point P
Intersection point of line segment connecting c and point Pd (2) Intersection point of line segment connecting point P _S1 and point Pe and line segment connecting point Pb and point Pd (3) Point P _S2 and point Pe An intersection of the line segment connecting the point P and the line segment connecting the point Pa and the point Pc (4) The intersection of the line segment connecting the point P _S2 and the point Pe and the line segment connecting the point Pc and the point Pd

Also, the point P_S1Includes the line segment connecting the point Pe with
The linear function is [y = a₁₁・ X + b₁₁], A₁₁, B
₁₁Is the point P_S1And the coordinates of the point Pe (x_S1, Y_S1), (X_e,
y_e), Point P_S2And a line segment connecting the point Pe and
The linear function [y = a₁₂・ X + b₁₂], A₁₂,
b₁₂Is the point P_S2And the coordinates of the point Pe (x_S2, Y_S2),
(X _e, Y_e) Is more specific.

Further, the points Pa (x _a , y _a ) and the points Pb (x
_a, y _b), the point _{Pc (x c, y a)} , the point Pd (x _c, y
Regarding _b ), in the case of this processing pattern 2, the y-coordinates of the points Pa and Pc, the y-coordinates of the points Pb and Pd are the same, and the x-coordinates of the points Pa and Pb and the points Pc and Pd of the points Pc and Pd are the same. The x coordinates are the same.

Therefore, a linear function including the line segment connecting the point P _S1 and the point Pe, a linear function including the line segment connecting the point P _S2 and the point Pe, and the points Pa, Pb, and Pc. , (1) to (4) can be examined by using the relationship between the points Pd. However, if the y coordinate of the point P _S1 and the point Pe is the same (y _S1 = y _e), next to y = y _S1, in this case, line segment connecting the point P _S1 and the point Pe, the point It coincides with the line segment connecting Pa and the point Pc, the point of intersection with the virtual body of the font data is the point Pc, and the y coordinates of the point P _S2 and the point Pe are the same (y _S2 =
If it is y _e) is next to y = y _S2, in this case, the line segment connecting the point P _S2 and the point Pe is consistent with the line connecting the point Pb and a point Pd, the font data virtual body The intersection with and becomes the point Pd. Therefore, when the y coordinates of the point P _S1 and the point Pe are the same, the intersection point is set as the point Pc and the above (1) and (2) are set.
When the y coordinate of the point P _S2 is the same as that of the point Pe, the intersection point is defined as the point Pd, and the above (3) and (4) are omitted.

First, in (1), a linear function [y = a ₁₁ · x + b ₁₁ ] including a line segment CL1 connecting the point P _S1 and the point Pe is
The y-coordinates (y = a ₁₁ · x _c + b ₁₁ ) when the x-coordinates (x _c ) of the points Pc and Pd are substituted are shown in FIGS. 35 (a) and 35 (b).

If it is within the range between (x _c ), that is, (x coordinate of point P _S1 , point P _S2 ) <
In the case of (x coordinate of point Pe), as shown in FIG. 35 (a), when x _a <x (= (y _b −b ₁₁ ) / a ₁₁ ) ≦ x _c , and (point P _S1 , X coordinate of point P _S2 )> (x of point Pe

Not the case for x _a . Moreover, this coordinate intersections CP ₁ when intersections CP ₁ (2) is present _{(x (= (y b -b} 11)
/ A ₁₁ ), y _b ).

Next, (3) is a linear function [y = a ₁₂ · x + b ₁₂ ] including a line segment CL2 connecting the point P _S2 and the point Pe, and the y coordinate (y _a of the point Pa and the point Pc). ) x coordinate when substituting _{(x = (y a -b 12} ) / a 12) is, x-coordinate of the point Pa (x

Next, in step S31, the placement start point specifying unit 5 determines, based on the intersection obtained in step S28,
Arrangement start points Pa and Pb of the font data corresponding to the next character to be currently processed are calculated.
So since the line segment connecting the point P _S1 and the point P _S1 is parallel to the y-axis (or the y-axis), passes through the intersection CP ₁ or / and CP ₂ obtained, the point P _S1 and the point P _S2 A line parallel to the line segment connecting to and the line segment connecting the point P _S1 and the point Pe, and the point P _S2

Therefore, for example, when the intersection point CP ₁ is obtained, the line parallel to the line segment connecting the points P _S1 and P _S2 passing through the intersection point CP ₁ and the points P _S2 and Pe are connected. The y coordinate of the intersection with the connecting line segment is the x coordinate of the intersection CP ₁ (x x _cp1 )

It can be obtained by substituting it into a linear function including a line segment connecting the point P _S1 and the point Pe. Furthermore, when the intersection points CP ₁ and CP ₂ are obtained, the coordinates of the intersection points CP ₁ and CP ₂ become the coordinates of Pa and Pb as they are.

As described above, based on the size, arrangement position, color density (the same as the method of obtaining the processing pattern 1) of each font data in the case of this processing pattern 2, the rotation angle θ, the long flat body ratio, etc. As the output control unit 12 outputs each font data, each font data is arranged far and near so as to converge from the points P _S1 and P _S2 to the point Pe, as shown in FIG.

Further, the arrangement patterns of FIGS. 37 and 38 (a) to (d) show the difference in the arrangement state of the font data depending on the setting method of the points P _S1 , P _S2 , and Pe. .

FIG. 37 (a) shows a case where the point Pe is located in the upper left direction of the figure with a straight line passing through the points P _S1 and P _S2 sandwiched therebetween.
For example, the slope of a straight line (linear function) passing through the points Pa _S1 and P _S2 is positive, and the x coordinate when the y coordinate of the point Pe is substituted into the linear function is more than the x coordinate of the point Pe. It is a big case. Incidentally, the point P _S1, is a linear function passing through the point P _S2, the point P _S1,
It can be specified from the coordinates of the point P _S2 . This FIG.
Hereinafter, the array pattern such as (a) is referred to as “array pattern Ta”.

[0206] Figure 37 (b) is the point P _S1, across the straight line passing through the point P _S2, if the point Pe is in the upper right direction in the figure, for example, the point P _S1, the linear function passing through the point P _S2 This is a case where the gradient is negative and the x coordinate when the y coordinate of the point Pe is substituted into the linear function is smaller than the x coordinate of the point Pe. A linear function passing through the points P _S1 and P _S2 in FIG.
The sign of the slope is opposite to that of the linear function passing through the points P _S1 and P _S2 in FIG. 37 (b). The array pattern as shown in FIG. 37 (b) is hereinafter referred to as "array pattern Tb".

In FIG. 37 (c), the x coordinate when the y coordinate of the point Pe is substituted into the linear function (having a negative slope) passing through the points P _S1 and P _S2 found in FIG. 37 (b) is This is the case where it is larger than the x coordinate of the point Pe. The array pattern as shown in FIG. 37 (c) is hereinafter referred to as "array pattern Tc".

The array pattern as shown in FIG. 37 (d) is hereinafter referred to as "array pattern Td".

They correspond to (d) respectively. Figure 37 (a)
The array patterns like (d) to (d) are hereinafter referred to as "array pattern Ya", "array pattern Yb", "array pattern Yc", and "array pattern Yd", respectively.

Next, in the preprocessing of step S3 in FIG. 2, the difference from the processing pattern 1 is the rotation angle θ of the font data at the time of output. The rotation angle θ will be described below in accordance with the above array patterns.

The rotation angle θ in the case of the array pattern Ta (FIG. 37 (a)) is, as shown in FIG. 39 (a), a straight line passing through the point P _S1 and parallel to the x-axis, and the point P _S1. , And the angle θ ₁ formed by a straight line passing through the point P _S2 . This angle θ ₁ is tan θ ₁ = (| y _S2 −y _S1 |) / based on the right triangle having the points P _S1 , P _S2 , and P _ip as vertices in FIG.
(| X _S2 −x _S1 |). Since the rotation direction in this case is counterclockwise, the rotation angle θ is obtained by adding “+” to θ ₁ obtained above.

The rotation angle θ in the case of the array pattern Tb (FIG. 37 (b)) is, as shown in FIG. 39 (b), a straight line passing through the point P _S1 and parallel to the x-axis, and the point P _S1. , And the angle θ ₁ formed by a straight line passing through the point P _S2 . The angle theta _1, and theta ₁ of the following cases is determined by the arrangement pattern Ta the same way. Since the rotation direction in this case is clockwise, the rotation angle θ is obtained by adding “−” to θ ₁ obtained above.

The rotation angle θ in the case of the array pattern Tc (FIG. 37 (c)) is, as shown in FIG. 39 (c), a straight line passing through the point P _S1 and parallel to the x-axis, and the point P _S1. , And the angle θ ₁ formed by a straight line passing through the point P _S2 . Since the rotation direction in this case is clockwise, the rotation angle θ is obtained by adding “−” to θ ₁ obtained above.

The rotation angle θ in the case of the array pattern Td (FIG. 37 (d)) is, as shown in FIG. 39 (d), a straight line passing through the point P _S2 and parallel to the x-axis, and the point P _S1. , And the angle θ ₁ formed by a straight line passing through the point P _S2 . Since the rotation direction in this case is counterclockwise, the rotation angle θ is obtained by adding “+” to θ ₁ obtained above.

The rotation angle θ in the case of the array pattern Ya (FIG. 38 (a)) is, as shown in FIG. 39 (e), a straight line passing through the point P _S2 and parallel to the x-axis, and the point P _S1. , 90 ° is added to the angle θ ₁ formed by the straight line passing through the point P _S2 .
In addition, since the rotation direction in this case is counterclockwise,
The rotation angle θ is obtained by adding “+” to (90 + θ ₁ ) obtained above.

The rotation angle θ in the case of the array pattern Yb (FIG. 38 (b)) is, as shown in FIG. 39 (f), a straight line passing through the point P _S2 and parallel to the x-axis, and the point P _S1. , The angle θ ₁ formed by a straight line passing through the point P _S2 is subtracted from 90 °. Since the rotation direction in this case is counterclockwise, the rotation angle θ is obtained by adding (+) to (90−θ ₁ ) obtained above.

The rotation angle θ in the case of the array pattern Yc (FIG. 38 (c)) is, as shown in FIG. 39 (g), a straight line passing through the point P _S1 and parallel to the x-axis, and the point P _S1. , 90 ° is added to the angle θ ₁ formed by the straight line passing through the point P _S2 .
Since the rotation direction in this case is clockwise, the rotation angle θ is obtained by adding “−” to (90 + θ ₁ ) obtained above.

The rotation angle θ in the case of the array pattern Yd (FIG. 38 (d)) is, as shown in FIG. 39 (h), a straight line passing through the point P _S1 and parallel to the x-axis, and the point P _S1. , The angle θ ₁ formed by a straight line passing through the point P _S2 is subtracted from 90 °. Since the rotation direction in this case is clockwise, the rotation angle θ is obtained by adding (−) to (90−θ ₁ ) obtained above.

Next, in step S4 of FIG. 2, the processing for obtaining the size, arrangement position and color density of each font data is executed. Here, steps S22, S25, S26, S28, and S31 (see FIG. 4) are different from the processing pattern 1 described above. These processes will be described below.

First, the method of obtaining the size of the font data in step S22 will be described. In this processing pattern 3, the x-coordinates of the given placement start points Pa and Pb,
Since y coordinates are both different, here, the arrangement start point given Pa, the coordinates of _{Pb (x a, y a)} , (x b, y
_The method of obtaining the dimensions is explained as _b ).

Here, each array pattern Ta, Tb, T
For c, Td, Ya, Yb, Yc, and Yd, if the long flat body ratio is not set, if the flat body ratio is set, or if the long body ratio is set, the points Pa, Pb, etc. The position is shown in FIGS. FIG. 40 shows the arrangement pattern Ta, FIG. 41 shows the arrangement pattern Tb, FIG. 42 shows the arrangement pattern Tc, and FIG. 43 shows the positions of points Pa, Pb, etc. according to the long flat body ratio setting state of the arrangement pattern Td. Show. Further, FIG. 44 shows the arrangement pattern Ya, FIG. 45 shows the arrangement pattern Yb, and FIG. 46 shows the arrangement pattern Yc.
Is a point P corresponding to the setting state of the long flat rate of the array pattern Yb
The positions of a, point Pb, etc. are shown respectively.

In the case of (a) and (b) of FIGS. 40 to 43 (when both the long body ratio and the flat body ratio in vertical assembly are not set and the flat body ratio is set), and Figure 44-
In the cases of (a) and (c) of FIG. 47 (when both the long body ratio and the flat body ratio in horizontal writing are not set and when the long body ratio is set), it is apparent from the figure. In addition, the size of the font data corresponds to the length between Pa and Pb. The length L between Pa and Pb can be calculated by the following formula. _{L = √ ((x b -x} a) 2 + (y b -y a) 2) ......... (22-21)

Therefore, in the above case, the dimension specifying unit 4 returns the L obtained by the equation (22-21) to the character arrangement processing unit 1 as the dimension of the font data.

Further, in the case of (c) of FIGS. 40 to 43 (when the length ratio in vertical assembly is set), the character width X is compressed by the length ratio (lp%). X'is Pa,
It is the length between Pb. Therefore, the character width X before the character width is compressed can be obtained by the following formula. X = (100 * X ') / (100-lp) = (100 * L) / (100-lp) ... (22-22) Here, L is calculated | required by said Formula (22-21). Pa, Pb
The length is between.

Since the size of the font data in this case is the size of the font data of character width X × character height Y (X = Y), the size specifying unit 4 uses the formula (22- 2
The X obtained in 2) is returned to the character arrangement processing unit 1 as the size of the font data.

In the case of (b) of FIGS. 44 to 47 (when the flatness rate in horizontal writing is set), the character height Y is compressed by the flatness rate (hp%). Y'is P
It is the length between a and Pb. Therefore, the character height Y before the character height is compressed can be obtained by the following formula. Y = (100.Y ') / (100-hp) = (100.L) / (100-hp) (22-23) where L is calculated by the above formula (22-21). Pa, Pb
The length is between.

Since the size of the font data in this case is the size of the font data of character height Y × character width X ((X = Y), the size specifying unit 4 uses the expression (22
-23) Return Y obtained as a font data size to the character arrangement processing unit 1.

Next, in the processing of step S25, the character arrangement processing unit 1 obtains the coordinates of the two points Pc and Pd other than the points Pa and Pb at the four corner points of the virtual body IB of the font data. How to obtain this will be described below with reference to FIGS.

For example, in the case of FIG. 40A, the coordinates (x _c , y _c ) of Pc and the coordinates (x _d , y _d ) of Pd can be obtained by the following equations. Here _{x c = x a -x R1 y} c = y a + y R1 x d = x b -x R1 y d = y b + y R1, x R1, y R1 corresponds to the h, t in the drawing, h is |
y _b -y _a |, t is | a | x _b -x _a. Note that x _R1 and y _R1 in the following description correspond to h and t in each figure, and h and t are also obtained in each figure in the same manner as above.

Further, in the case of FIG. 40B, the coordinates (x _c , y _c ) of Pc and the coordinates (x _d , y _d ) of Pd can be obtained by the following formulas. _{x c = x a -x R2 y} c = y a + y R2 x d = x b -x R2 y d = y b + y R2

Here, x _R2 and y _R2 are obtained by the following equations. x _R2 = (x _R1 × (100-hp) / 100)) y _R2 = (y _R1 × (100-hp) / 100))

Further, in the case of FIG. 40 (c), the coordinates (x _c , y _c ) of Pc and the coordinates (x _d , y _d ) of Pd can be obtained by the following equations. _{x c = x a -x R3 y} c = y a + y R3 x d = x b -x R3 y d = y b + y R3

Here, x _R3 and y _R3 are h'and t'in the figure.
And h ′ and t ′ are obtained by the following equations. h '= (hx (100-hp) / 100)) t' = (tx (100-hp) / 100))

In each of FIGS. 41 to 47, since the positional relationship of Pa, Pb, Pc, and Pd in the output area is different, x _R1 , x _R2 , and x _R3 are added to x _a and x _b. Do or subtract, and y _a , y _b have y _R1 , y _R2 , y
Basically, the coordinates of Pc and Pd can be obtained by the same method as in each case of FIG. 40, although _R3 is added or subtracted. The coordinates of Pc and Pd are shown in each figure.

Next, in step S26, the character arrangement processing unit 1 arranges the font data from the points Pa, Pb, Pc, Pd based on the positional relationship of the points P _S1 , P _S2 , Pe and the set direction. Determine the position (reference point of virtual body).

As can be seen from FIGS. 40 to 47, this is the case in each of FIGS. 40, 41, 46 and 47, that is, in the case of the array patterns Ta, Tb, Yc and Yd, the point Pa is It becomes the lower left of the virtual body IB, that is, in each case of FIGS. 44 and 45, that is, in the case of the array patterns Ya and Yb, the point Pb becomes the lower left of the virtual body IB.
2, each case of FIG. 43, that is, the array patterns Tc, T
In the case of d, the point Pc is the lower left of the virtual body IB.

Therefore, the array patterns Ta, Tb, Yc,
In the case of Yd, the arrangement position becomes the coordinates of the point Pa, in the case of the arrangement patterns Ya and Yb, the arrangement position becomes the coordinates of the point Pb, and in the case of the arrangement patterns Tc and Td, the arrangement position becomes the coordinates of the point Pc. .

Next, in step S28, the arrangement start point specifying unit 5 causes the point P _S1 , the point P _S2 , the point Pe, the point Pa, the point Pb,
A line segment connecting the point P _S1 and the point Pe and the point P _S2 and the point when the font data corresponding to the current character to be processed is virtually arranged in the output state based on the points Pc and Pd. The intersection of the line segment connecting Pe and the virtual body of the font data corresponding to the current character to be processed is obtained. The method of obtaining the intersection in the case of this processing pattern 3 will be described below.

Also in this case, the intersection point of the line segment connecting the point P _S1 and the point Pe and the line segment connecting the point P _S2 and the point Pe with the virtual body IB of the font data corresponding to the current character to be processed is determined. As in the case of the processing pattern 1, only the following cases (1) to (4) exist.

Can be obtained. y _S1 = a _cd · x + b _cd

Further, a line segment CL1 connecting the point P _S1 and the point Pe
If the linear function including x is [x = x _S1 ], the linear function including the line segment CLcd connecting the point Pc and the point Pd [y = a _cd ·

_cp1 ≤ x _d (in the case of Fig. 49 (b) and (d)), or
When x _{d ≤x cp1} <x _b (in the case of FIGS. _{49A and} 49C), the intersection point of the line segment CL1 connecting the point P _S1 and the point Pe and the line segment connecting the point Pb and the point Pd CP ₁ will exist. Since the points P _S1 , _Ps2 , and Pe are not located on a straight line, x _b = x _cp1 is excluded from the determination conditions. Intersection CP when intersection CP ₁ exists in this (2)
The x coordinate of ₁ is the above x _CP1 , and the y coordinate of the intersection point CP ₁ is a linear function [y = a _bd · x + b] including a line segment CLcd connecting the x coordinate (x _CP1 ) between the point Pb and the point Pd. _bd ] to obtain.

Also, a line segment CL1 connecting the point P _S1 and the point Pe
Even when the linear function including is also [x = x _S1 ], the y coordinate (y _cp1 ) of the intersection point of each linear function is obtained in the same manner as (1) above.
That is, as shown in FIG. 49, the y coordinate (y _b ) of the point Pb.
And y is within the range between the y coordinate (y _d ) of the point Pd, that is, y _b <y _cp1 ≦ y _d (FIG. 49 (a),
(In the case of (b)), or y _d ≤ y _cp1 <y _b (Fig. 49)
In the case of (c) and (d)), an intersection C of a line segment CL1 connecting the point P _S1 and the point Pe and a line segment connecting the point Pb and the point Pd
P ₁ will exist. Since the points P _S1 , _Ps2 , and Pe are not located on a straight line, y _b = y
_cp1 is excluded from the judgment conditions. The coordinates of the intersection point CP _{1 in} this case are (x _S1 , y _CP1 ).

Next, in (3), as in (1) above, the point P
_A linear function including a line segment CL2 connecting _S2 and the point Pe, and a point P
The x-coordinate (or y-coordinate) of the intersection point with the linear function including the line segment CLac connecting a and the point Pc is obtained, and the x-coordinate (or y-coordinate) is the x-axis of the point Pa as shown in FIG. If it falls within the range between the coordinate (or y coordinate) and the x coordinate (or y coordinate) of the point Pc, the intersection point CP ₂ exists. In addition, the intersection point CP when the intersection point CP ₂ exists
The coordinates of ₂ are obtained by the same method as (1) above.

Next, in (4), as in (1) above, the point P
_A linear function including a line segment CL2 connecting _S2 and the point Pe, and a point P
The x-coordinate (or y-coordinate) of the intersection point with the linear function including the line segment CLcd connecting c and the point Pd is obtained, and the x-coordinate (or y-coordinate) is the x-axis of the point Pc as shown in FIG. If it is within the range between the coordinate (or y coordinate) and the x coordinate (or y coordinate) of the point Pd, the intersection point CP ₂ is present. In addition, the intersection point CP when the intersection point CP ₂ exists
The coordinates of ₂ are obtained by the same method as (1) above.

Next, in step S31, the placement start point specifying unit 5 determines, based on the intersection obtained in step S28,
Arrangement start points Pa and Pb of the font data corresponding to the next character to be currently processed are obtained.

For example, as shown in FIGS. 52 (d) to 52 (f),
When the intersection points CP ₁ and CP ₂ are obtained, the intersection points CP ₁ and CP ₂ become the placement start points Pa and Pb of the font data corresponding to the character next to the character to be currently processed.

Further, FIGS. 52 (a) to 52 (c) and (g) to
When either _one of the intersection points CP ₁ or CP ₂ is obtained as in (i), first, the intersection points CP ₁ or CP ₂
Line parallel to the line segment that passes through the point P _S1 and the point P _S2 (1
Next function) IL is calculated. This is [y = a _ab · x +
When b _cp], the inclination a _ab are the parallel to the line segment connecting the point P _S1 and the point P _S2, the slope of the linear function including a line segment connecting the point P _S1 and the point P _S2 Will be the same. The slope of the linear function including a line segment connecting the point P _S1 and the point P _S2 are the coordinates (x _S1, y _S1) of the point P _S1 and the point P _S2, be determined from (x _S2, y _S2) You can Therefore, the a _ab can be specified. In addition, the above linear function [y = a _ab · x + b _cp ]
B _cp is specified by substituting the x-coordinate and y-coordinate of the obtained intersection point CP ₁ or CP ₂ . Therefore, it is possible to specify a linear function expression that represents the line IL that passes through the intersection point CP ₁ or CP ₂ and is parallel to the line segment that connects the point P _S1 and the point P _S2 .

Next, the linear function [y = a _ab.x +
b _cp ], and a line segment connecting the point P _S1 and the point Pe (when the intersection point CP ₂ is obtained), or a line segment connecting the point P _S2 and the point Pe (when the intersection point CP ₁ is obtained) Find the intersection with.

Further, the linear function including the line segment connecting the point P _S1 and the point Pe and the linear function including the line segment connecting the point P _S2 and the point Pe are, respectively, as described in step S28 above. [Y = a ₂₁ · x + b ₂₁ ], [y = a ₂₂ · x + b ₂₂ ].

Therefore, for example, when the intersection point CP ₁ is obtained (in the case of FIGS. 52A to 52C), the intersection point CP ₁ becomes Pa, and the x coordinate of Pb is obtained by the following formula. You can a ₂₂ · x + b ₂₂ = a _ab · x + b _cp Then, the obtained x coordinate of Pb is [y = a _ab · x +
b _cp ] or [y = a ₂₂ · x + b ₂₂ ], P
The y coordinate of b is obtained.

If the intersection point CP ₂ is determined (in the case of FIGS. 52 (g) to (i)), the intersection point CP ₂ is set to P.
It becomes b, and the x coordinate of Pa can be calculated by the following formula. a ₂₁ · x + b ₂₁ = a _ab · x + b _cp Then, the calculated x coordinate of Pa is [y = a _ab · x +
b _cp ] or [y = a ₂₁ · x + b ₂₁ ], P
The y coordinate of a is obtained.

As described above, based on the size, arrangement position, color density (same as the method of obtaining the processing pattern 1) of each font data in the case of this processing pattern 3, the rotation angle θ, the long flat body ratio and the like, The output control unit 12 outputs the respective font data, so that the respective font data can be obtained as shown in FIGS.
As shown in FIG. 8, the perspective arrangement is performed so that the points P _S1 and P _S2 converge to the point Pe.

In the above-described embodiment, the change rate of the color density of each font data is obtained in advance in the preprocessing of step S3 of FIG. 2, and the change rate and the current change rate are calculated in step S27 of FIG. Although the color density of each font data is calculated based on the order (i) of the characters to be processed, in step S27 of FIG. 4, the start color density, the end color density, and the total number of characters from the character arrangement processing unit 1 are calculated. The present invention may be configured such that the current order of characters to be processed is given and the color density of the font data is obtained by the following formula based on these data. Color density of the current font data to be processed = {((end color density-start color density) x (i-1)) / (total number of characters-
1)} + starting color density Note that this modification and the following modifications can be similarly applied to the embodiments described later.

In the above embodiment, the color density of each font data to be output is gradually changed from the start color density to the end color density based on the set start color density and end color density. However, the font data may be output with the same color density. At this time, if the color density at the time of output is specified and all the font data is output at that color density, the formatted data table 7
Although the area for storing the color density (see FIG. 11) may be provided for each character processing data portion FAi of each font data, for example, the header portion HA is provided with an area of <color density> and output. In the processing, the output control unit 12 may be configured to output each font data with the color density stored in the <color density> area of the header portion HA. Further, if the font density is not specified at the time of output and all font data is output with the default color density that the output device has in advance, the color density is stored in the typesetting data table 7. There is no need to provide an area.

Further, in the above-mentioned embodiment, the composition direction is designated, but the apparatus may be structured such that the composition direction is not designated and the composition is performed only in a predetermined composition direction.

Further, in the above-mentioned embodiment, the long flat body ratio is designated, but the long flat body ratio is not designated,
The apparatus may be configured so that only the font data of the square virtual body is used for typesetting.

Next, the configuration of the second embodiment device of the present invention will be described with reference to FIG. FIG. 53 is a block diagram showing the configuration of the second embodiment device. Note that the portions denoted by the same reference numerals as those in FIG. 1 are the same as those in the configuration of FIG. 1, so detailed description thereof will be omitted here. This second embodiment device is mainly described in claim 2.
And an embodiment corresponding to the invention described in claim 3 subordinate to claim 2.

The feature of the second embodiment device is that the rotation processing unit 31 is provided, and the line segment connecting the arrangement start points P _S1 and P _{S2 of} the font data corresponding to the set first character is defined as x in the output area. The point P _S2 (or the point P _S1 ) and the set convergence point Pe are rotated by a predetermined angle about the point P _S1 (or the point P _S2 ) so as to be parallel (or coincident) with the axis or the y-axis. _Find point P _S2 '(or point P _S1 '), point Pe ',
Character arrangement processing unit 1, dimension specifying unit 4, arrangement start point specifying unit 5
Then, the point P _S1 (or the point P _S2 ) and the point P _S2 '(or the point P _S2
S1 ') and the point Pe', the size and the arrangement position of each font data are specified, and the character arrangement processing unit 1 obtains the obtained point P _S1 (or point P _S2 ) and point P _S2 '(or point P _S2 ). _S1 '),
The arrangement position of each font data with respect to the point Pe 'is rotated in the opposite direction about the point P _S1 (or the point P _S2 ) by the above-mentioned predetermined angle, and each font data for the point P _S1 , the point P _S2 , and the point Pe is rotated. It is configured so as to obtain the arrangement position of. With this configuration, when the line segment connecting the arrangement start points P _S1 and P _{S2 of} the font data corresponding to the first character is set to be inclined with respect to the x axis (y axis) of the output area. Moreover, it becomes easy to calculate the size and arrangement position of each font data.

The rotation processing section 31 corresponds to the rotation processing means in the present invention, and the character arrangement processing section 1 in this embodiment corresponds to the reverse rotation processing means in the present invention.

A specific processing procedure will be described with reference to the flowchart in FIG. The flowchart of FIG. 54 is obtained by adding steps S2-1 and S4-1 to the flowchart of FIG.

Steps S1 and S2 are the same processes as those of the apparatus of the first embodiment, and the arrangement start points P _S1 , P _{S2 of} the text data, the font data corresponding to the first character, the convergence point Pe, the set direction instruction, The long flatness ratio, the start color density, and the end color density are captured. The coordinates of the captured points P _S1 , P _S2 , and Pe are (x _S1 , y _S1 ), (x _S2 , y _S2 ),
Let (x _e , y _e ).

[0268] Next, the rotation processing unit 31, P _S1 given point from the character arrangement processing unit 1, the point P _S2, performs rotation processing of the point Pe (step S2-1). Here, points P _S1 and P
_The point P _S2 and the point P _S2 are centered on the point P _S1 so that the line segment connecting the line _S2 is parallel (or coincident) with the x-axis of the output region.
It is assumed that a point P _S2 'and a point Pe' obtained by rotating e with a predetermined angle are obtained. The case where the line segment connecting the points P _S1 and P _S2 coincides with the x axis is the case where the y coordinate of the point P _S1 is “0”.

This will be described with reference to FIG. For example, when points P _S1 , P _S2 , and Pe are set as shown in FIG. _55A , a line segment connecting the points P _S1 and P _S2 is parallel to (or coincides with) the x-axis of the output area. ), _Let point P _S1
As can be seen from FIG. 55 (b), the rotation angle δ when the point P _S2 and the point Pe are rotated about
It can be obtained from nδ = | y _s2 −y _s1 | / | x _s2 −x _s1 |. As for the rotation direction, counterclockwise rotation is positive and clockwise rotation is negative. Therefore, from FIG.
As shown in (d), (y coordinate of point P _S1 (y _S1 ))>
When (y coordinate of point P _S2 (y _S2 )), δ becomes positive, and (y
_{When S1} ) <(y _S2 ), δ becomes negative. Note that (y _S1 ) =
When (y _S2 ), the rotation angle δ becomes “0 °”. Further, as shown in FIGS. 57A and _57B , when a line segment connecting the points P _S1 and P _S2 is parallel (or coincides) with the y axis of the output region (the x coordinate of the point P _S1 ( x _S1 ) = the x coordinate (x _S2 ) of the point P _S2 ), the rotation angle δ becomes “90 °”.

[0270] Next, about the point P _S1, y coordinate y ₄ of the point P _S2 [delta] point is rotated P _S2 'is, y coordinates of the point P _S1 (y
Becomes the same as _S1), also, the x-coordinate x ₄ of the point P _S2 'is the x-coordinate of the point P _S1 (x _S1), the point P _S1, the length between the points P _S2 (√
Obtained by adding the ^{_{((y S2 -y S1) 2}} + (x S2 -x S1) 2)).

The coordinates (x ₅ , y ₅ ) of the point Pe ′ obtained by rotating the point P _S2 by δ about the point P _S1 can be obtained by the following affine transformation formula. x ₅ = (x _e −x _S1 ) · cos δ− (y _e −y _s1 ) · s
_{inδ y 5 = (x e -x} S1) · sinδ + (y e -y S1) · c
osδ

The rotation processing unit 31 calculates the rotation angle δ obtained by the above processing and the coordinates (x ₄ , y ₄ ) of the points P _S2 'and Pe'.
(X ₅ , y ₅ ) is given to the character arrangement processing unit 1.

Returning to FIG. 54, next, in the preprocessing of step 3, setting data and the like are set in predetermined areas of the typesetting data table 7, the typesetting auxiliary data table 8, and the work area 21. , In this second embodiment device,
In the <x coordinate of P _S2 >, <y coordinate of P _S2 >, <x coordinate of Pe>, and <y coordinate of Pe> of the work area 21, the point P _S2 obtained by the rotation processing of the above step S2-1. The coordinates of ', Pe' are set, and the coordinates of the point P _S2 'is set in <x coordinate of Pb>, <y coordinate of Pb>. This allows
In the processing of step S4 below, the point P _S1 and the point P _S2 '(the placement start point of the font data corresponding to the first character is set to the point P _S1) .
_S1 , the point P _S2 '), and the convergence point Pe' are used to obtain the size and arrangement position of each font data.

The rotation angle θ stored in the <rotation angle θ> area of the typesetting data table 7 is based on the set points P _S1 , _Ps2 , Pe and the set direction, and is the processing pattern of the first embodiment. It can be determined by the method described in 1 to 3.

The rotation angle θ is determined by the set point P _S1 ,
It can also be obtained based on the points P _S2 and Pe, the set direction, and the rotation angle δ obtained by the rotation process of step S2-1. For example, the rotation processing result of FIG. 37A is as shown in FIG. 9C. The rotation angle θ in FIG. 9C is “0 °”. Therefore, the rotation angle θ in the case of FIG. 37A may be reversely rotated from the rotation angle θ (“0 °”) of FIG. 9C by the rotation angle (− | δ |) during the rotation processing. Therefore, (0 ° − (− | δ |)) = (| δ |), and the rotation angle θ in the case of FIG.
δ |).

Further, the rotation processing result of FIG. 37 (c) is as shown in FIG. 9 (d). Since the rotation angle θ in FIG. 9D is also “0 °”, the rotation angle θ in the case of FIG. 37C is (0 ° − | δ |) = (− | δ |), and FIG. In the case of d), it also becomes (| δ |).

The rotation processing result of FIG. 38 (a) is as shown in FIG. 9 (a). The rotation angle θ in FIG. 9A is “90 °”. However, considering that the center of rotation of the font data at this time is P _S2 ,
(90 ° + | δ |), and in the case of FIG. 38 (b),
Similarly, it becomes (90 ° − | δ |).

The rotation processing result of FIG. 38 (c) is as shown in FIG. 9 (b). Since the rotation angle θ in FIG. 9B is “−90 °”, the rotation angle θ in the case of FIG. 38C is (−90 ° − | δ |), and FIG.
Similarly, the rotation angle θ in the case of (d) is (−90 ° − (−
| Δ |)) = (− 90 ° + | δ |).

The rotation processing result of FIG. 32 (a) is as shown in FIG. 9 (a). Since the rotation angle θ in FIG. 9A is “90 °” and the rotation angle δ in this case is “90 °”, the rotation angle θ in the case of FIG. 32A is (90 ° −90 °). ) = “0 °”, and FIG.
Similarly, the rotation angle θ in the case of (b) is (−90 ° − (−
90 °)) = “− 180 °” (or “180 °”)
Becomes

Further, the rotation processing result of FIG. 32 (a) is as shown in FIG. 9 (a). Since the rotation angle θ in FIG. 9A is “90 °” and the rotation angle δ in this case is “90 °”, the rotation angle θ in the case of FIG. 32A is (90 ° −90 °). ) = “0 °”.

Further, the rotation processing result of FIG. 32 (b) is as shown in FIG. 9 (b). Since the rotation angle θ in FIG. 9B is “−90 °” and the rotation angle δ in this case is “90 °”, the rotation angle θ in the case of FIG. 32B is (−90 ° −). 90 °) = “− 180 °” (or
“180 °”).

Further, the rotation processing result of FIG. 32 (c) is as shown in FIG. 9 (c). The rotation angle θ in FIG. 9C is “0 °”, and the rotation angle δ in this case is “9”.
Since it is “0 °”, the rotation angle θ in the case of FIG. 32C is (0 ° −90 °) = “− 90 °”.

Further, the rotation processing result of FIG. 32 (d) is as shown in FIG. 9 (d). The rotation angle θ in FIG. 9D is “0 °”, and the rotation angle δ in this case is “9”.
Since it is “0 °”, the rotation angle θ in the case of FIG. 32D is (0 ° −90 °) = “− 90 °”.

Since the rotation angle δ of the rotation processing is “0 °” in FIGS. 9A to 9D, each rotation angle θ is “90 ° -0 °” (= "90 °"),
"-90 ° -0 °" (= "-90 °"), "0 ° -0
“” (= “0 °”) and “0 ° -0 °” (= “0 °”).

Returning to FIG. 54, next, in step S4 (see FIG. 4), the size, arrangement position, and color density of each font data corresponding to each character forming the text data are obtained. However, here, as described above, the point P
_Since the size and the arrangement position are obtained based on _S1 , the point P _S2 ', and the point Pe', the character arrangement processing unit 1, the size specifying unit 4, and the arrangement start point specifying unit 5 perform the size and arrangement according to the processing procedure related to the processing pattern 1. The placement position will be obtained.

For example, the points P _S1 , P _S2 , and Pe are shown in FIG.
When set as shown in (a) and when typesetting vertically (see Fig. 3)
7 (a)), the dimensions and arrangement positions P ₁ ′ to P ₅ ′ obtained in step S4 are as shown in FIG. 58 (a). In FIG. 58, the virtual body IB corresponding to the obtained dimensions is
It shows with. However, the placement start point and the convergence point of the font data corresponding to the actually set first character are point P.
_S1, the point P _S2 ', the point Pe' instead, the point P _S1, the point P _S2, a point Pe. Therefore, the output result must be as shown in FIG. 58 (b). Here, as can be seen by comparing the Figure 58 (b) Fig. 58 and (a), the point P _S1, the point P _S2 ', the point Pe' and the positional relationship, the point P _S1, the point P _S2, the point P
a triangle relative to the positional relationship of e same (point P _S1, the point P _S2 ', the point Pe' of the vertex, the point P _S1, the point P _S2, the point Pe
(It is congruent with the triangle with the vertex as), so the obtained dimensions are not affected by the rotation process. Further, since the color density is determined by the start color density, the end color density, the number of characters, and the order of characters, it is not affected by the rotation processing. However, arrangement positions, a point P _S1, the point P _S2 ', the point Pe' since determined based on,
It is different from the original arrangement position for the points P _S1 , P _S2 , and Pe. Therefore, the obtained arrangement positions P ₁ ′ to P ₅ ′ are the original arrangement positions P _{1 to} P with respect to the points P _S1 , _Ps2 , and Pe.
Needs to be modified to ₅ . This is performed by the process of step S4-1 in FIG.

Specifically, as shown in FIG. 58 (c),
The obtained arrangement positions P ₁ ′ to P ₅ ′ are rotated about the point P _S1 by the rotation angle δ in the direction opposite to the rotation processing of step S2-1. The arrangement positions P _{1 to} P ₅ after the rotation in the opposite direction can be obtained by the following affine transformation formula. _{x Pi = (x Pi '-x} S1) · cos (-δ) - (y Pi' -
y _S1 ) · sin (−δ) y _Pi = (x _Pi ′ −x _S1 ) · sin (−δ) + (y _Pi ′ −
y _S1 ) · cos (−δ) where (x _Pi ′, y _Pi ′) are the coordinates of the obtained arrangement positions P ₁ ′ to P ₅ ′, and (x _Pi , y _Pi ) is obtained. These are the coordinates of the original arrangement positions P _{1 to} P ₅ that should be used. In this case, i = 1, 2, 3, 4, 5. However, when the center of the rotation process (in this case, the point P _S1 ) is the same as the layout position P ₁ of the font data corresponding to the first character (FIG. 3).
7 (a), (b), FIG. 38 (c), (d), etc.), since the coordinates of the arrangement position P ₁ 'and the coordinates of P ₁ are the same, the above i is 2 to 5, that is, the first. The reverse rotation processing of the arrangement position of the font data corresponding to the character is unnecessary.

Arrangement positions P _{1 to} P thus obtained
By outputting the font data of the size obtained in step S4 to ₅ , the typesetting result corresponding to the set typesetting instruction is output.

As described above, in this embodiment, the character arrangement processing section 1, the dimension specifying section 4, and the arrangement start point specifying section 5 always operate regardless of the positional relationship between the set points P _S1 and P _S2. Since the respective dimensions, arrangement positions and the like can be obtained according to the calculation procedure of the processing pattern 1, the calculation is simplified. Further, in the above-described first embodiment, the programs related to the processing patterns 1 to 3 are prepared, and the set points P _S1 and P
_It is necessary to appropriately select the programs of the processing patterns 1 to 3 according to the positional relationship of _S2 to obtain the dimensions and the arrangement position, but in the second embodiment, only the program related to the processing pattern 1 is facilitated. Since this is sufficient, the configuration of the apparatus (memory capacity for storing programs, control of processing procedure, etc.) becomes simple.

[0290] In the above description, as to parallel the line segment connecting the point P _S1 and the point P _S2 in the x-axis of the output area (or match), around the point P _S1, the point P _S2 and the point Pe the predetermined angle is allowed by the point P _S2 ', the point Pe' has been sought, around the point P _S2, the point P _S1 and the point P _S1 and the point Pe rotated by a predetermined angle ', the point Pe' to seek You may comprise. However, the rotation direction at the time of the rotation processing at this time is opposite to the case where the point P _S1 is the center, that is, (y coordinate of point P _S1 (y _S1 ))> (y coordinate of point P _S2 (y _S2 ). ), Δ becomes negative, and when (y _S1 ) <(y _S2 ), δ becomes positive.

Also, the point P is arranged so that the line segment connecting the points P _S1 and P _S2 is parallel (or coincident) with the y axis of the output area.
_{With S1} (or point P _S2 ) as the center, point P _S2 (or point P _S2 )
_S1 ) and the point Pe are rotated by a predetermined angle to obtain a point P _S2 '(or a point P _S1 ') and a point Pe ', and the points P _S1 and P _S2 ',
Based on the point Pe '(or the point P _S1 ', the point P _S2 , the point Pe '), the size and the arrangement position of each font data are obtained, and the obtained arrangement position is centered on the point P _S1 (or the point P _S2 ). The original arrangement position may be obtained by rotating in the opposite direction by the predetermined angle. However, at this time, the character arrangement processing unit 1 or the like sets the size and the arrangement position for the point P _S1 , the point P _S2 ′, and the point Pe ′ (or the point P _S1 ′, the point P _S2 , and the point Pe ′) to the processing pattern 2. The configuration is obtained by the processing procedure.

[0292]

As is apparent from the above description, according to the first aspect of the invention, the font data is set from the placement start points P _S1 and P _{S2 of} the font data corresponding to the set first character. The size and the arrangement position of the rectangular font data corresponding to the respective characters forming the set text data are calculated so as to converge to the convergence point Pe, and the font data are arranged in the perspective and are output. It is possible to obtain the typesetting result in which the characters of the font data are not distorted, and the characters are arranged in a visually natural perspective arrangement based on the characters.

Since the character corresponding to the font data output based on the obtained size and arrangement position is read from the font by the character code, the character (the font data corresponding to) the character corresponding to the formatted result Corrections, insertions, deletions, etc. can be handled mainly by changing the character code and shifting, etc., so it is possible to flexibly respond to corrections, insertions, deletions, etc. of characters (font data corresponding to) in the typesetting result, compared to conventional devices. can do.

According to the second aspect of the invention, the calculation of the size and the arrangement position of each font data by the character arrangement processing control means, the dimension specifying means, and the arrangement start point specifying means is performed at the set point P. Point P so that the line segment connecting _S1 and point P _S2 is parallel (or coincident) with the coordinate axis of the output area.
_{With S1} (or point P _S2 ) as the center, point P _S2 (or point P _S2 )
_S1 ), the point Pe is rotated by a predetermined angle, and the operation is performed based on the obtained points P _S2 ′, Pe ′ and P _s1 (or P _s1 ′, Pe ′ and P _s2 ). Therefore, this calculation process is simplified.

Further, according to the invention of claim 3,
Since each font data is colored so as to gradually change from the set arrangement color density to the end color density, it is possible to create a leaflet or the like that looks good and attracts the viewer's attention.
