2. Description of the Related Art For a designed rectangular figure, a halftone dot generating process for generating a halftone dot, a pouring process for pouring text data, and the like are performed. In order to perform such processing, it is necessary to specify a specific rectangular figure as a processing target from a plurality of rectangular figures displayed on the screen for designing. In particular, when processing the inside, it is necessary to specify the inside of the closed area formed by the rectangular figure.

The conventional rectangular closed area designation processing is performed by placing a mouse pointing point inside the rectangular closed area and clicking a mouse button. The reason why the rectangular closed area is designated by such an operation, that is, the processing for determining the closed area in the system is performed in the following process steps (1) to (3). Specify a point in the plane coordinate system, generate a line segment starting from the specified point, select one of the figures in the plane coordinate system, and specify the number of intersections of the selected figure and the line Is r and the other intersections are 1 and the accumulated intersections are calculated. If the number of intersections is odd, it is determined that the figure contains points, and if the number of intersections is even, it is determined that the figure does not contain points. If the figure does not include the point, select another figure in and repeat the following process. If the figure contains the point,
The pixel adjacent to the point is traced to the boundary of the figure, and the set of all the adjacent pixels forms a closed area of the figure.

FIG. 2C is a diagram showing an example in which halftone dot generation processing is performed within a frame of a table of ruled line graphics by using two points as designated points. As shown in FIG. 2 (B), the hatching is performed in the smallest frame including the two designated points. In this case, the two designated points are two small rectangular frames arranged diagonally with respect to the desired rectangular frame.

Before explaining the processing steps of the processing for discriminating closed regions for the above processing, the structure of graphic data will be described. FIG. 3 is a diagram showing the contents of a rectangular graphic and a table of the rectangular graphic data. There are horizontal and vertical tables. The contents of each table are as follows. ◆ Horizontal table This is composed of X coordinate, range y coordinate, y sub coordinate, rounded radius, and segment number. X-coordinate: Representative coordinates Range y-coordinate: Effective range of y-axis coordinates of the above coordinates y Sub-coordinate: Area for recording rounded corner position Rounded radius: Rounded rounded position Area for recording the radius (circle in the figure is actually a numerical value) Segment number: This is the figure management number and is used for maintenance of the table contents when the figure is modified.

◆ Vertical table Y coordinate, range x coordinate, x sub coordinate, corner radius, segment number. Y-coordinate: Representative coordinates Range x-coordinate: Effective range of x-axis coordinates of the above coordinates x Sub-coordinate: Area where the rounded position is recorded Corner radius: Rounded corner Area for recording the radius (circle in the figure is actually a numerical value) Segment number: This is the figure management number and is used for maintenance of the table contents when the figure is modified.

Target figures for which such a table is created include straight lines, rectangles, continuous lines (horizontal line segments, vertical line segments), equal dividing lines, and the like. The vertical line segments generated by these figures are stored in the horizontal table, and the horizontal line segments generated by these figures are stored in the vertical table. Also,
In the case of a rectangle, there is also a rectangle having rounded corners, and in that case, it is necessary to store the rounded corner condition in the table. Regarding the corners of the rectangle, the upper left corner is corner 1, the upper right corner is corner 2,
When the lower left corner is named corner 3 and the lower right corner is named corner 4, corner 1 and corner 4 are reflected in the horizontal table regarding the rounded corner condition. Further, the corner 3 and the corner 2 are reflected on the vertical table regarding the rounded corner condition.

As described above, FIG. 3 is a diagram showing the contents of the rectangular graphic and the table of the rectangular graphic data.
The table contents are described as shown in (A), FIG. 3 (B), FIG. 3 (C), and FIG. 3 (D). FIG. 4 is a diagram showing the contents of a table of more complicated rectangular figures and the rectangular figure data. 4A shows the complicated rectangular figure, FIG. 4B shows the horizontal table of the rectangular figure of FIG. 4A, and FIG. 4C shows the vertical shape of the rectangular figure of FIG. 4A. Show table.

Next, the rectangular closed area discrimination processing using the above table will be described. FIG. 5 is a flow chart showing the process of the rectangular closed area discrimination processing. First, on the main screen on which design data such as block copy data is displayed, one point of the target rectangular figure for discriminating the closed area is designated. The one point has coordinates (α, β) (S1). Next, the horizontal tables of all the rectangular graphic data forming the design data are referred to, and the data of one graphic is read from the horizontal table as reference data (S2). Candidate points are extracted from the reference data according to the following rules (S
3).

With respect to the coordinate value "α", the horizontal table is referred to, and the candidate points smaller and larger than α and the candidate points larger and smaller than α are searched in the horizontal table. Again, it is determined whether the coordinate value "β" is within the y coordinate range. If the result of determination is that it is outside the range, the next candidate point is obtained (S4). All points that have sub-coordinates are target coordinates, so all are extracted. If there are no sub-coordinates, select arbitrary.

Next, the vertical tables of all the rectangular graphic data forming the design data are referred to, and the data of one graphic is read from the vertical table as reference data (S5). Candidate points are extracted from the reference data according to the following rules (S6). With respect to the coordinate value “β”, the vertical table is referred to, and a candidate point smaller than β and larger than β and a candidate point larger than and smaller than β are searched in the vertical table. At this time, it is determined whether the coordinate value "α" is within the x coordinate range. If the result of determination is that it is outside the range, the next candidate point is obtained (S7). All points that have sub-coordinates are target coordinates, so all are extracted. If there are no sub-coordinates, select arbitrary. Next, collation processing is performed to finally determine the rectangular area (S
8).

For example, in FIG. 4, when the coordinate of the designated point 12 is (α, β), the horizontal table is searched based on the coordinate α and the following three points are candidates.

The vertical table is searched based on the coordinate β, and the following two points are candidates.

The sub-y coordinate of the three candidate points on the X coordinate side and the point on the Y coordinate side are collated. As a result, since the point A at the Y coordinate is checked at X and Y, the following area is finally obtained. Rectangular area coordinates (a, a), (c, b) Corner position Corner 1 Corner radius ◎

Although the case of designating one point has been described above, it is clear that the same process can be performed in the case of designating two points, and therefore the detailed description will be omitted. In short, the designated points are (α1, β1) and (α2, β2),
Regarding the coordinate values “α1” and “α2”, refer to the horizontal table, and in the horizontal table, the candidate point that is smaller and the largest than “the smaller one of α1 and α2”, and “the larger one of α1 and α2” Find the largest and smallest candidate points. Again, it is determined whether the coordinate values “β1” and “β2” are within the y coordinate range. As a result of the determination, if either one is out of the range, the next candidate point is obtained (S4), and the transformation operation may be performed.

Next, the form design system of the present invention in which the above-mentioned rectangular closed area discrimination processing method is applied to the form design system will be described. In the form design system described below, the rectangular closed area determination processing method is performed as a pre-stage of the processing in the process of performing some processing inside the figure.
