Abstract

PURPOSE:To provide a data processor by which a square and round related with the delete of a ruled line can be automatically canceled by deleting the ruled line. CONSTITUTION:First of all, the ruled line data of the ruled line connected with the ruled line to be deleted are retrieved (step 14). Next, the square and round radius in the retrieved ruled line data is checked (step 15), and when an 'R' is set at an intersected point side with the ruled line to be deleted, the pertinent square and round radius is cleared to an 'O' (step 16). After the square and round radius is cleared, the rule line data of the horizontal line to be deleted are deleted (step 17). Afterwards, the plotting of the ruled line based on the changed ruled line is operated (step 18), and the processing is ended.

EXAMPLES Examples of the present invention will be described below.

FIG. 1 is a block diagram of a data processing device according to an embodiment of the present invention, in which 1 is a central processing unit (hereinafter referred to as CPU) for controlling the device and data processing, and 2 is a program or the like. Read-only memory (hereinafter referred to as ROM) that stores data, 3 is a random access memory (hereinafter referred to as RAM) that stores data, 4 is RAM
A ruled line data storage unit for storing data regarding ruled lines in 3; a data buffer for temporarily storing data in process, etc .; 6 for an input unit such as a keyboard and a mouse; 7 for storing bitmap data for output Image memory, 8
Is a CRT display (hereinafter referred to as CRT).

The ruled line data storage unit 4 has a horizontal ruled line information storage unit 4-1 and a vertical ruled line information storage unit 4-2 which store data of horizontal ruled lines and vertical ruled lines, respectively.

The horizontal ruled line is managed for each horizontal ruled line having the same Y coordinate value as shown in FIG. In the horizontal ruled line information, the Y coordinate management table has a pointer to the X coordinate management table. Further, the X coordinate management table has a pointer to the Y coordinate value / ruled line data management table of the ruled line managed by itself. The ruled line data management table is the start point of the ruled line (whichever of the two end points of the horizontal ruled line has the smaller X coordinate value).
It has an X coordinate and a pointer to ruled line data. The ruled line data managed by the ruled line data management table includes the X coordinate of the start point and the end point of the ruled line (of the two end points of the horizontal ruled line, whichever has the larger X coordinate value), the line type information, and the rounded radius RH1 · R.
It has H2, RH3, and RH4 (the rounded corners are numbered at the intersections of the ruled lines and defined at four places as shown in FIG. 8. Therefore, when a certain horizontal ruled line is used as a reference, The upper side is rounded D2, the lower side is rounded D3, the upper end is rounded D1, and the lower side is rounded D4, and the rounded radii RH1 to RH
4 is the radius of curvature of the rounded corner portion corresponding to each number. In this embodiment, the radius of the rounded corner is a constant, and the radius of the rounded corner is R when the rounded corner is set, and is 0 when the rounded corner is not set).

A new horizontal ruled line is set, and Y of the horizontal ruled line is set.
If the coordinates are the same as any of the horizontal ruled lines that have already been set, first, the ruled line data of the new ruled line and the ruled line data management table corresponding thereto are created, and the ruled line data management table in the X coordinate management table is created. To a pointer to
A pointer value to the newly created ruled line data management table is added. If they are not the same, a new X coordinate management table is created corresponding to the ruled line data and the ruled line data management table created in the same manner as above, and the new X coordinate management table in the Y coordinate management table is created. A new value is added to the pointer of.

The vertical ruled lines are managed for each vertical ruled line having the same X coordinate value as shown in FIG. In the vertical ruled line information, the X coordinate management table has a pointer to the Y coordinate management table. Further, the Y coordinate management table has a pointer to the X coordinate value / ruled line data management table of the ruled line managed by itself. The ruled line data management table shows the start point of the ruled line (of the two end points of the vertical ruled line, whichever has the smaller Y coordinate value).
Has a Y coordinate and a pointer to ruled line data. The ruled line data managed by the ruled line data management table includes Y coordinates, line type information, and rounded radiuses RV1 and R of the start point and the end point (of the two end points of the vertical ruled line, whichever has the larger Y coordinate value) of the ruled line.
It has V2, RV3, and RV4 (in the case of vertical ruled lines, as is clear from FIG. 8, the left side of the starting point of the ruled line is rounded D4, the right side is rounded D3, the left side of the end point is rounded D1, and the right side is rounded round. D2
Therefore, the rounded corner radii RV1 to RV4 are the radii of curvature of the rounded corners corresponding to the respective numbers, and take a value of R or O).

When a new vertical ruled line is set, the vertical ruled line information is updated in the same manner as the horizontal ruled line.

In the case of this embodiment, as shown in FIG.
A case where a total of four ruled lines, that is, horizontal ruled lines L2 and L4 and vertical ruled lines L1 and L3 are set will be described. P1 in the figure
P5 is the starting point or the ending point of the ruled line, and (x, y) is the coordinate value of each point.

The operation of the data processing apparatus of this embodiment having the above configuration will be described below with reference to the flow charts of FIGS.

First, in step 1, when the input unit 6 instructs one intersection (P2) of a plurality of ruled lines displayed on the CRT 8, in step 2, the CPU
1 searches the horizontal ruled line storage unit 4-1 and the vertical ruled line storage unit 4-2 for ruled line data of a ruled line whose start point or end point is the designated point (P2) (in this case, in FIG. The ruled line data 10 and 6 of the horizontal ruled line L2 and the ruled line data 116 of the vertical ruled line L1 are searched). Next, based on the input of the data regarding the rounded corners (hereinafter referred to as the rounded corner information) from the input unit 6 in step 3, the rounded corner information is set in the corresponding horizontal ruled line data or vertical ruled line data in step 4. The rounded corner information is data including a direction in which the rounded corner is set with the intersection as a reference (upper left / upper right / lower right / lower left), a ruled line with the rounded corner, and a rounded radius R (in the case of the present embodiment, It is assumed that the direction is the upper right of the point P2, and the ruled lines are the vertical ruled line L1 and the horizontal ruled line L2, so that the corner radius RV2 of the ruled line data 116 of the vertical ruled line L1 and the corner of the ruled line data 106 of the horizontal ruled line L2. Round radius RH2 is set to R). When the setting of the rounded corner information is completed, in step 5, the ruled line is drawn on the CRT 8 based on the changed ruled line data.

The ruled line drawing method will be briefly described below with reference to FIG. Drawing of a ruled line is performed based on a coordinate sequence of points on the ruled line. The CPU 1 creates a coordinate sequence of points on each ruled line from the ruled line data in the ruled line information storage unit 4, writes the coordinate sequence in the data buffer 5, and writes an image based on the coordinate sequence in the data buffer 5. Memory 7
Write the ruled line bitmap data into. The bitmap data in the image memory 7 is transferred to the CRT 8 and the ruled lines are displayed.

When the CPU 1 creates a coordinate sequence,
First, the radius of the rounded corner in the ruled line data is checked. If all the corner radii are “O” in the initial state, it means that no corner is set for the ruled line, and therefore the coordinates of the start point and the end point of the ruled line are written in the data buffer 5 as they are.
If "R" is set for any of the corner radiuses, it depends on which corner radius is set (in the case of a horizontal ruled line, the corner radiuses RH1 to RH4. The corner radii RV1 to RV4.) Recognize which part of the ruled line the corner is set, and a coordinate sequence of points on the curve of the corner is created. In the rounded portion, first, the center O of the arc is obtained, and the coordinate sequence (Q1, ..., QN) of the points on the arc is created thereby. In the case of the present embodiment, as a result, a coordinate sequence for each ruled line as shown in FIG. 10 is created in the data buffer 5.

The processing when the ruled line is deleted in the rounded portion set as described above will be described.

First, when the ruled line (L1) displayed on the CRT 8 is designated from the input section 6 in step 11, the CPU 1 determines the ruled line data (116) of the designated ruled line (L1) in step 12. Is searched in the ruled line data storage unit 4, and the ruled line is deleted in step 13.

The ruled line deleting process will be described below with reference to FIG. First, in step 14, the ruled line data (1
06). This is done using the coordinates of the start and end points of the specified ruled line. Next, in step 15, the radius of the rounded corner in the retrieved ruled line data is checked, and if “R” is set on the side of the intersection with the ruled line designated in step 11, then in step 16, the corresponding rounded corner is rounded. The radius is cleared to “O” (in the case of the present embodiment, the rounded radius RH2 in the ruled line data 106 in the horizontal ruled line information storage unit 4-1 is set to “O”). After the rounded radius is cleared, in step 17, the ruled line data (116) of the ruled line designated in step 11 is added to the vertical ruled line information storage unit 4-2.
Deleted from within. Then, in step 18, a ruled line is drawn based on the changed ruled line data, and the process ends. The details of the drawing of the ruled lines are the same as in step 5, and therefore the description thereof is omitted here.

As described above, in the present embodiment, when one ruled line is deleted in the part where the corner is set to be rounded, the information about the rounded set to the other ruled line is also automatically set. Therefore, the rounded corners are automatically released by deleting the ruled line, and it is possible to provide a data processing device having excellent operability.

In this embodiment, the processing for deleting a ruled line has been described. However, even if the ruled line is moved so that it does not intersect with the other ruled line, the rounded corners can be released by the same process. It is possible.
