BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a graphic editing apparatus and method for processing an image using a computer, and more particularly, to graphic editing for editing a graphic such as a circuit diagram, a block diagram, a flow chart, or a tree. An apparatus and a method.

2. Description of the Related Art Conventionally, as a device for drawing a circuit diagram, as shown in FIG. 31, a pin pair information selection storage means 92 for sequentially selecting only two points of a starting point and an ending point of a connecting line and storing the two points, A wiring prohibition area storage unit 91 for storing a wiring prohibition area in which a figure is arranged, and a right-angled polygonal line connecting a start point and an end point with a continuous straight line that is bent at a right angle according to the position coordinates of the two points, avoiding the wiring prohibition area. Wiring means 90
Is to have. According to the conventional example, the pin pair information selection / storing means 92 sequentially selects only the starting point and the ending point of the connecting line and stores the two points. When the right-angled polygonal line automatic wiring means 90 determines that the connection line drawn between the pin pairs passes through the wiring prohibited area stored in the wiring prohibited area storage means 91, according to the position coordinates of the two points, Connect the start point and end point with a continuous straight line that bends at a right angle.

[0003]

In the conventional example, the connection is made by a continuous straight line that is bent at a right angle. However, as long as each figure is a circuit diagram using a rectangle or a square,
When wiring is performed so as to be bent at a right angle, there is an advantage that the wiring is easy to see because the wiring is along each side and the calculation for obtaining the wiring is easy. However, if each shape is not limited to a square or rectangle, or if you want to draw a tree structure or tree diagram, or if you want to connect the shapes with smooth curves, the connecting lines that connect the shapes should be at right angles. Bending straight lines are not appropriate, but diagonal lines and curved lines are required. Also, unlike the pin position of each element on the circuit, if the position of the intersection point where the figure and the connection line intersect, or the connection source point and the connection destination point is not fixed, each connection point is flexibly determined. There is a need. Furthermore, when a line overlaps with one or more figures, there is a case where it is desired to draw a line having a different type from the outside of the figure within the area of the figure. Therefore, the present invention is
When connecting various shapes that are not limited to squares and rectangles with connecting lines, or when the connecting points between each figure and the connecting line are not fixed, etc. The object of the present invention is to provide a graphic editing apparatus and method capable of easily performing high-quality graphic editing.

[0004]

In order to solve the above technical problems, the first invention, as shown in FIG. 1, draws a line on an arranged figure in a state where overlap with the figure is eliminated.

This overlap is based on the coordinates of the connection points and break points of the connection lines, which is the connection line information read from the graphic / connection line information storage unit 80, and the coordinates / size of the figures, which is the graphic information. -The figure overlap detection unit 40 can easily obtain the value analytically. When there are a plurality of overlapping figures, the figure closest to the connection origin point or the bending point on the side close to the connection origin point is sequentially obtained.

Then, the connection lines are arranged by the connection line arrangement section 42. In step S24, the line / graphic overlap detection unit 30 is activated again, and the overlap between the detour point c and the connection point b is checked. In step S25, as shown in FIG. 13C, between the detour point and the connection destination point,
When the overlap between the connecting line and the figure is detected, the process returns to step S22 again, and the detour point selecting unit 31 selects the detour point. The above processing is performed until the overlap with the figure is no longer detected.

Further, the optimum connection point calculation unit 44, as shown in the figure, is a figure that is connected from the figure / connection line information storage unit 80 to a connection line at a connection source point, and a vertex that represents the shape for each figure. And a graphic information etc. extraction unit 44e for extracting graphic information and connection line information regarding the representative point,
The side forming the figure is calculated from the coordinates of the extracted vertices, and the side intersecting the connecting line connecting the representative point and the connection source point or the connection destination point is defined by the coordinates of the extracted vertices, the representative point, and the connection source.

Next, the operation according to the second embodiment will be described with reference to FIG.
And it demonstrates based on FIG. In this example, FIG.
As shown in (a), the break point connected to the connection point is a point b.
, The connected figure is a square figure C, and its vertex is c1,
C2, c3, and c4, and the central point d of the square is adopted as the representative point. Also, for all connection lines,
It is assumed that it has the connection destination point, the coordinates of a plurality of break points, the connection identification number of the connection source graphic and the connection destination graphic, and the vertex number that identifies the side to be connected. These pieces of information are extracted from the figure / connecting line information storage section 80 as the figure information and the connecting line information by the figure information extracting section 44e. As shown in FIG. 15A, in step S40,
The closest break point detecting unit 43 detects the closest break point b connected to the connection destination point (connection source point) and the connection destination graphic C connected to the connection line based on the graphic information and the connection line information. To do. If there is no break point, the connection source point (connection destination point) becomes the closest break point b. Step S41
Then, the optimum connection point calculation unit 44 calculates the optimum connection point. The calculation of the optimum connection point is, as shown in FIG. 15B, in step S50, the vertices c1, c2, c3 of the graphic C extracted by the graphic information extraction unit 44e.
Based on c4, the intersecting side detection unit 44c finds the side of the figure C. In step S51, the intersection side detection unit 44c
Finds a straight line connecting the center point d and the closest bending point b. In step S52, the side intersecting the straight line is obtained. The vertices of the sides calculated in this way are recorded in the vertex numbers that identify the sides connected to the connection destination. In the example of FIG. 16, they are c2 and c3 as shown in FIG. Step S5
At 3, the connection line detecting unit 44d for each intersecting side obtains all the connecting lines connected to the side. That is, the connecting lines having the same numbers as the vertex numbers obtained in step S52 are listed. These are all connecting lines that connect to the same side of the same figure. In step S54, the angle calculator 44a enumerates the angles between the connecting line and the side. From the connection line listed in step S53, a straight line connecting each of the closest bending points and the midpoint of the side specified by the vertex number and the angle of this side are obtained. In this case, as shown in FIG. 16C, the side is used as a reference and the clockwise direction is positive. In step S55,
The interior division point calculation unit 44b allocates interior division points of this side in descending order of angle. As a result, the internally dividing point divides the side into the number of connecting lines plus one (the number of internally dividing points is the same as the number of connecting points).
Each internal division point becomes a connection destination point (or connection source point) of each connection line, a connection point as shown in FIG. 16D is obtained, and the connection line is arranged at each connection point. In step S56, the interior dividing point calculation unit 44b determines whether or not the connecting lines intersect with each other. If the connecting lines intersect with each other, the internal dividing points are allocated to the connecting lines in ascending order of angle in step S57. The connection points are rearranged by the above procedure. In a similar procedure, in steps S42 and S43, the connection origin point is calculated from the closest bend point connected to the connection destination and the figure connected to the connection line at the connection source.

As shown in the figure, the image data editing unit 73 detects line / figure overlap detection for detecting the overlap between the figure and the connecting line connecting the specified original point and the specified point. Part 4

A connecting line area dividing unit 47 that divides the connecting line area into a predetermined area, and a connecting line arranging unit 48 that arranges the connecting lines such that adjacent connecting line areas such as an area inside the figure and an area outside the figure have different types. It is a thing. Further, the intersection point calculation unit 47 calculates a side of each figure based on the figure information etc. extraction section 47b for extracting the figure information etc. from the figure / connection line information storage section 80, and calculates the intersection point. And an intersection calculation unit 47a.

The operation of the graphic editing apparatus and method according to this embodiment will be described with reference to FIGS. 18 and 19. For example, as shown in FIG. 19A, a connection line is drawn from the connection source graphic to the connection destination graphic, and the connection source point is the point a and the connection destination point is the point b. As shown in FIG. 18, step S60
Then, the line / graphic overlap detecting unit 46 detects a graphic (square) overlapping the connection line. Step S61
If a figure that overlaps the connecting line is detected, the process proceeds to step S62, where the intersection calculating unit 47a sets all the sides forming the detected overlapping figure to the figure information from the figure / connecting line information storage unit 80. It is obtained from the vertices of the figure extracted by the equal extraction unit 47c, and the intersection point is obtained from the information about these sides and the extracted connecting lines. Step S6
In 3, the connection line area dividing unit 47 divides the connection line into a plurality of areas by dividing the connection line at the intersection, the original point, or the destination point with the connection line. When there are n intersections, if the intersections are c1, c2, ... C _n from the original point to the destination point, a to c1, c
Areas where 2 to c3, ... Do not overlap with the figure, c1 to c2, c
3 to c4 ... Are areas that overlap the figure. In FIG. 17A, a to c1 are non-overlapping areas and c1 to c2 are overlapping areas. When the connection source point a is included in the figure as shown in FIG. 7D, the overlapping portion and the non-overlapping portion are reversed. When the connection line is divided in this way,
The connection line arranging section 48 arranges connection lines of different types in adjacent connection line regions. For example, in FIG. 19 (b),
The area of the connecting line in the figure between the intersection c1 and the intersection c2 is displayed by changing the dotted line, the alternate long and short dash line, the color and the like.
