Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ruled line output method capable of visually enhancing a ruled line.

[0002]

2. Description of the Related Art In an information processing device such as a desktop publishing system, when performing spreadsheets,
A rectangular table consisting of a set of ruled lines is displayed. And you can highlight a part of this table.

FIG. 8 shows an example in which a rectangular table is displayed on the display screen in the above information processing apparatus. In FIG. 8, 7
a is a display screen and CH is a table. Then, the user surrounds the total column (rectangular area) of the table CH with ruled line groups LX1 and LX.
It is assumed that 2, LY1, LY2 are made thicker than the other ruled lines and the total column is desired to be highlighted.

Now, in the above-mentioned information processing apparatus, generally, FIG.
As shown in 0, the ruled line L has an end point P (X
1, Y1), Q (X2, Y2) and the line width b. Then, as indicated by the broken line in FIG. 8, a ruled line group whose line width is to be changed is designated. FIG. 9 is an enlarged view showing the vicinity of the designated ruled line group (line width b0) LX1, LX2, LY1, LY2. Next, the user inputs the changed line width b1.

[0005]

However, in the information processing apparatus using the conventional ruled line output method, only the line width is changed from b0 to b1 without changing the position of the center line of the ruled line group to be changed. It was supposed to output. Therefore, as shown in FIG. 11, the changed ruled line group LX
The outer edges of 3, LX4, LY3 and LY4 are, for example, arrow Y1.
And the arrow Y2, these ruled line groups LX3, LX
4, LY3, LY4 do not coincide with the outer edges of other ruled lines, and a large number of convex portions U appear, resulting in a poor appearance of the entire table as an output result.

Further, in such a case, if the user corrects the changed ruled line group one by one in order to improve the appearance, there is a problem that the work efficiency decreases. It was

In view of the above-mentioned problems, it is an object of the present invention to provide a ruled line output method capable of visually enhancing a ruled line.

[0008]

In order to solve the above problems, the present invention provides a step of acquiring the line width of a changed ruled line group, and a ruled line connected to this line width and the ruled line group to be changed. And the line width of the changed ruled line group, the step of obtaining a movement amount in which the outer edge of the changed ruled line group matches the outer edge of the connected ruled line, and the changed ruled line group is moved to the inside of the rectangular area by this movement amount. A step of drawing data in a drawing memory and outputting this dot data constitutes a ruled line output method.

[0009]

With the above configuration, the outer edge of the changed ruled line group is moved and output so as to coincide with the outer edge of the ruled line connected thereto. Therefore, it is possible to obtain a beautiful output result without any unevenness that deteriorates the appearance of the output result.

Embodiments of the present invention will now be described with reference to the drawings.

FIG. 1 is a block diagram of an information processing apparatus using a ruled line output method according to an embodiment of the present invention, FIG. 2 is a block diagram of a horizontal ruled data area in the information processing apparatus, and FIG. FIG. 4 is a configuration diagram of the data area, FIG. 4 is an explanatory diagram of the movement amount, FIG. 5 is a flowchart showing a processing flow of the ruled line output method of the present embodiment, FIG. 7 is a partially enlarged view of the display screen after the line width is changed.

In FIG. 1, 1 is a CPU, and 2 is an RO that stores a program following the flow shown in FIG.
M, 3 are RAMs provided with horizontal ruled data area 3a, vertical ruled data area 3b, etc., 4 is a keyboard for the user to input necessary information such as line width, and 5 is drawing for storing drawing dot data. An image memory as a memory, 6 is a VRAM, 7 is a CRT having a display screen 7a, 8 is a printer, and 9 is a bus connecting the above-mentioned elements. The ruled line output method of this embodiment is realized by the CPU 1 executing a program (according to the flowchart of FIG. 5) stored in the ROM 2.

FIG. 2 shows a horizontal ruled data area 3a in the RAM 3.
Shows an overview of the data structure of. When the end point (x, y) of the center line of the ruled line is obtained, the ruled line data part corresponding to this end point (x, y) is reached via the horizontal ruled table, the Y coordinate table pointer, and the ruled line data part pointer. It is possible to read and write the line width information and position correction information of the ruled line data portion (information that the center line of the ruled line is moved to the inside of the rectangular area when the line width is enlarged). . Moreover, in the horizontal ruled line, 2 of the center line of the ruled line is used.
Since the two endpoints have the same y coordinate but different x coordinates,
In the horizontal rule management table, the y-coordinate is branched first, and then the Y-coordinate table pointer is branched at the x-coordinate. Since it did in this way, reading and writing of data can be performed quickly. The vertical ruled data area 3b is shown in FIG. The vertical ruled data area 3b has substantially the same structure as the horizontal ruled data area 3a.
However, in FIG. 2, "horizontal" means "vertical",
In this configuration, “y” is replaced with “x” and “x” is replaced with “y”.

The information processing apparatus using the ruled line output method of this embodiment has the above-mentioned configuration. Next, this ruled line output method will be described with reference to FIGS.

First, a range for changing the line width is designated (step 1). Specifically, it is designated as shown by the broken line in FIG. 6, and the ruled line group LX1, LX2, LY1, LY within this broken line is specified.
2 is changed. As a result, these ruled line groups LX
1, LX2, LY1, LY2 center line groups each 2
Get two endpoints. A, B, C and D are intersections of these center line groups, and S is these ruled line groups LX1, LX2.
It is a rectangular area surrounded by LY1 and LY2.

Next, the ruled line LX is calculated from the coordinates of the end point group.
1 and LX2, the horizontal ruled line data area 3a is set to the ruled line L
For Y1 and LY2, the vertical ruled line data area 3b is searched (step 2). Next, a message is displayed on the display screen 7a to prompt the user to input the line width (the changed line width b1) of the target ruled line group from the keyboard,
This line width b1 is acquired (step 3). Then, the position correction information of the ruled line data portion of each of these ruled line groups is set to the inside of the rectangular area S (step 4).

Next, the ruled line groups LX1 and L to be changed
It is determined whether or not there is a ruled line connected to X2, LY1, and LY2 (step 5). If there is a ruled line, the process proceeds to step 6, and if not, the process proceeds to step 7. In step 6, the horizontal ruled data area 3a and the vertical ruled data area 3b are searched to obtain the line width of the ruled line to be connected. In the example of FIG. 6, this line width is b0.

The ruled line groups LX1 and L to be changed
