Description of the Related Art In the conventional enlargement / reduction function, when a new character is input, an enlargement ratio (or a reduction ratio) is designated in advance, and a character pattern representing each character is input according to the character input by the operator. This is realized by sequentially creating patterns that are enlarged (reduced) and developed in the display memory.

Further, as shown by underlining in FIG. 6 (a), there is also one in which a character string in an input document is designated and the designated character string is enlarged or reduced collectively. In this case, as shown in FIG. 6 (b), a pattern obtained by enlarging (reducing) each character included in the corresponding character string is expanded in the display memory, and then the character string that is continuous with the original character string. The pattern corresponding to is expanded. At this time, each of the new patterns is simply sequentially expanded from the start coordinates of the pattern corresponding to the start character of the original character string to the end coordinates of the line including the character string.

[0006]

By the way, as described above, in the conventional character enlarging / reducing function, a new pattern is simply developed, so that the range of enlarging / reducing is within the document. The coordinates had to be continuous.

For this reason, characters in free-form blocks in a document are grouped together, such as a block consisting of portions of the same column in a plurality of lines as shown by shading in FIG. 6 (c). Could not be enlarged or reduced.

It is an object of the present invention to provide a Japanese word processor capable of enlarging or reducing the characters in a free-form block in a document all at once.

Embodiments of the present invention will now be described in detail with reference to the drawings. FIG. 2 is a block diagram of an embodiment of the Japanese word processor of the present invention.

In FIG. 2, the Japanese word processor has a structure in which a keyboard 201, a CRT display (CRT) 202, and a memory 220 are connected to a main controller 210.

The memory 220 described above is the document holding means 1
The display area 221 corresponding to 01 is divided into a display area 221 and a work area 222, and the pattern expanded in the display area 221 is displayed 202 corresponding to the output unit 102 via the display control unit 211 of the main control unit 210. Entered in
The display 202 is configured to be displayed according to this pattern. Further, the format information storage unit 223 of the work area 222 stores the number of characters in one line, the number of lines in one page, the line interval, and the like as the format information regarding the format of the document being created.

In FIG. 2, the key code input via the keyboard 201 is converted into a character code indicating the corresponding character by the kana-kanji conversion processing unit 212 of the main control unit 210 and a control code indicating the attribute of the character. The data is converted, arranged by the allocation processing unit 213 into a document format based on the above-described format information, and developed in the display area 221.

A method for enlarging or reducing each character in a block in a document expanded in the display area 221 will be described below. FIG. 3 is a flowchart showing the enlarging / reducing operation by the Japanese word processor of the present invention.

In this case, the operator operates the keyboard 201 to specify the upper left character and the lower right character of the range to be enlarged or reduced to start the specified range, as shown in FIG. The position and the end position may be input (step 301).

In response to this, the cut-out processing unit 214 of the main control unit 210 first refers to the display area 221, and determines that the digit arrangement direction of the document is the X direction and the line arrangement direction is the Y direction. Coordinates (Xa, Ya), (Xb, Yb)
And the document in the display area 221 is divided into a plurality of blocks based on these coordinates. At this time, the cut-out processing unit 214, for example, as shown by a dotted line in FIG. 4, a block indicating a designated range (hereinafter referred to as a designated block) and four complementary blocks surrounding the designated block (denoted by symbols 1 to 4 in FIG. 4). ) And

In this case, the designated block has an X coordinate range of Xa <X <Xb, and a Y coordinate range of Ya.
It contains the characters <Y <Yb. Further, in the complementary block indicated by reference numeral in FIG. 4, the range of the X coordinate is Xa.
> X, and the complement block indicated by the symbol, is composed of characters whose X coordinate range is Xa <X and whose Y coordinate range is Ya> Y and Yb <Y, respectively. There is. The supplementary block indicated by the reference numeral is composed of characters whose X coordinate range is Xa> X and whose Y coordinate range is Ya <Y <Yb.

Next, the cut-out processing unit 214 detects all the characters included in the specified block, reads the character data indicating these characters from the display area 221, and together with the coordinates, the specified block in the work area 222. Storage 2
It stores in 24. At this time, the cutout processing unit 21
Similarly, for the four complementary blocks described above, 4 detects the characters included in each complementary block, and stores the corresponding character data and coordinates in the complementary block storage unit 225 for each complementary block.

After that, the operator inputs the scale factor for enlarging / reducing the designated block (step 30).
2) In response to this, the enlargement / reduction processing unit 215 of the main control unit 210 is activated.

The enlargement / reduction processing unit 215 sequentially reads the character data and the coordinates from the designated block storage unit 224 described above, enlarges or reduces the character data in accordance with the magnification input in step 302, and also the respective character data. The coordinates are calculated and sequentially sent to the enlargement / reduction data storage unit 226 (step 303).

The coordinates obtained by the enlargement / reduction processing unit 215 described above are also input to the coordinate calculation unit 216, and this coordinate calculation unit 216 is included in the complementary blocks to based on the input coordinates. The coordinates indicating the new position of each character are obtained, and the coordinates in the complementary block storage unit 225 are rewritten (step 304). Here, the enlargement / reduction processing unit 2
Reference numeral 15 may input the coordinates obtained for the lower right character of the designated block to the coordinate calculation unit 216 as the coordinates indicating the enlargement / reduction result of the designated block. Further, the coordinate calculation unit 216 may obtain the position of each boundary line after the deformation of the designated block from the input coordinates, and may obtain the coordinates of each character in the complementary block corresponding to the movement of each boundary line.

The coordinates thus obtained are sequentially sent to the judgment processing unit 217, and the judgment processing unit 217 responds to the coordinates corresponding to the coordinates of each character and the display range of the display 202. And the range is compared to determine whether or not each character is outside the display range (step 30).
5). Here, the determination processing unit 217 preliminarily determines the number of characters in one line from the format data storage unit 223 and the display 202.
The number of lines and line spacing displayed on the screen are read, the range of coordinates corresponding to the display range is calculated, and the range of these coordinates and the input coordinates are sequentially compared to determine whether or not to protrude. Then, the determination result may be notified to the display information creation unit 218 and the expansion processing unit 219.

In the case of a negative determination in this step 305, the expansion processing unit 219 operates and the respective character data and coordinates contained in the complementary block and the designated block are read from the complementary block storage unit 225 and the enlarged / reduced data storage unit 226, respectively. Is read out, each character data is developed in the display area 221 based on the corresponding coordinates (step 306), and the process is ended.

As described above, the cut-out processing unit 214 cuts out the designated block in accordance with the instruction of the operator, and the enlargement / reduction processing unit 215 performs the enlargement / reduction processing on the designated block to obtain the character data. Expansion processing unit 219
By expanding in the display area 221, the characters included in the specified range specified by the operator can be enlarged or reduced, and the function of the deforming unit 111 can be realized.

Further, the cut-out processing unit 214 cuts out the complementary block corresponding to the designated block in accordance with the operator's instruction, and the coordinate calculation unit 216 includes it in the complementary block according to the result of the enlargement / reduction processing of the designated block. New coordinates of each character to be obtained are obtained, and the expansion processing unit 219 expands the character data in the complementary block storage unit 225 based on the new coordinates, so that the specified block is deformed according to the deformation.
The storage location of each character data in the complementary block can be moved, and the function of the moving means 112 can be realized.

As a result, it is possible to collectively enlarge / reduce the characters contained in a freely shaped block, enhance the block editing function, and further improve the expressiveness of the Japanese word processor. You can

For example, if it is instructed in step 303 that the designated block should be enlarged twice in the horizontal direction, the document shown in FIG. 4 is converted into the document shown in FIG. 5 by the above-mentioned enlargement / reduction processing. In addition, only the characters included in the specified block are horizontally expanded to double, and the size of the characters included in the other complementary blocks remains the same, while the document whose position is moved according to the expansion of the specified block is obtained. To be In this case, using the difference Xd between the X coordinate of the end position and the start position of the original designated range, the position of the lower right character of the transformed designated block is indicated by the coordinate (Xa + 2Xd, Ya). The boundary line between the supplementary block and the symbol is moved by Xd in the X direction.

By thus enhancing the block editing function, it becomes possible to use the Japanese word processor as a desktop publishing system, and it is possible to expand the range of use of the Japanese word processor.

On the other hand, in the case of the affirmative determination in step 305 described above, in response to the notification from the determination processing unit 217, the display information creating unit 218 displays a message for notifying the operator that the characters are out of the display range. Information and display information for prompting the operator to input instructions regarding subsequent processing are created, and the display 202 is displayed via the display control unit 211.
(Step 307). At this time, the display information creating unit 218 may prompt the operator to input an instruction as to whether or not to perform the process of changing the designated range or the process of displaying the protruding portion by changing the line.

When the operator inputs an instruction to change the designated range in accordance with the display information displayed in step 307, a positive determination is made in step 308, the process returns to step 301, and the above-mentioned steps 301 to 301 are executed. Step 3
The process of 05 may be repeated again.

When the operator inputs an instruction to display the protruding portion in a different line, a positive determination is made in step 309, the complementary block storage section 225.
And the contents of the enlarged / reduced data storage unit 226 are sent to the allocation processing unit 213, and the allocation processing unit 213 performs allocation processing according to the format information (step 3
10) The processing may be ended after the data is expanded in the display area 221.

On the other hand, in the case of a negative determination in step 308, the flow proceeds to step 306 described above, the contents of the complementary block storage section 225 and the enlarged / reduced data storage section 226 are expanded in the display area 221, and the processing is ended. do it. In this case, the protruding portion is not displayed.

As described above, before moving the complementary block, the determination processing unit 217 determines whether all the characters in the complementary block are within the display range based on the coordinates obtained by the coordinate calculation unit 216. Then, the display information creation unit 218 and the display control unit 211 notify the operator of this determination result, thereby preventing erroneous deletion of a part of the document due to enlargement / reduction processing of the designated range. You can

Further, when all the characters in the complementary block are not included in the display range, the enlargement / reduction function of the designated range is made easier to use by asking the operator's instruction as described above. be able to.

[0036]

As described above, according to the present invention, the designated block is transformed, and the storage location of the character data corresponding to each character in the complementary block is moved in the document holding means according to the transformation result. With this, the complementary blocks can be combined in accordance with the deformation of the designated block, so that it is possible to collectively enlarge or reduce the characters in the blocks of arbitrary shapes. As a result, the block editing function of the Japanese word processor can be enhanced, and a word processor capable of various Japanese expressions can be realized.
