Abstract

PURPOSE:To equally allocate already plotted graphic forms with an easy operation. CONSTITUTION:A CPU 10 stores the coordinate data of a plotted free line in a free line plotting coordinate memory 24 and retrieves graphic data of graphics being in contact with the free line from a graphic data memory 16 and saves these graphic data Z1 to ZC in a graphic data work memory 26 and stores the number C of them in a variable memory 30. Next, the CPU 10 stores the overall length L and the start point S of the free line in the variable memory 30 based on coordinate data of the free line stored in the free line plotting coordinate memory 24 and deletes graphic data corresponding to graphic data in the graphic data work memory 26 from the graphic data memory 16. A graphic change control part 28 generates graphic data equally arranged on the free line based on graphic data in the graphic data work memory 26 and various variables in the variable memory 30 and writes these generated graphic data in the graphic data memory 16.

Retrieved from 6 (step S2), and the graphic data Z ₁ to Z _C of the retrieved figures with saving the graphic data work memory 26 (step S3), and the graphic change control unit 28 the number C of the retrieved figures It is stored in the variable memory 30 via (step S4).

Next, based on the coordinate data of the free line stored in the free line drawing coordinate memory 24, the total length L and the starting point S of the drawn free line are stored in the variable memory 30 via the figure change control unit 28. Then, the graphic data corresponding to the graphic data stored in the graphic data work memory 24 is deleted from the graphic data memory 16 (step S5) (step S6).

The graphic change control unit 28, as will be described in detail later, draws a drawn free line (curve 42A or continuous straight line 42) as shown in FIG. 3D or 3E.
B) The graphic data evenly arranged on the graphic data is created, and the graphic data is written in the graphic data memory 16 (step S7).

The figure drawing controller 18 reads out all the figure data in the figure data memory 16 (step S8) and redraws the figure data on the display memory 20, thereby arranging the figures evenly on the display screen of the display section 22. And drawn (step S9).

Next, the graphic modification process in step S7 will be described in more detail with reference to the flowchart of FIG.

First, the value of the total length L of the free line stored in the variable memory 30 is divided by the value obtained by subtracting "1" from the number C of retrieved figures also stored in the variable memory 30, and the solution is obtained. Is stored as an interval W in the variable memory 30 (step S71). Further, the value of the starting point S of the free line stored in the variable memory 30 is set to the drawing coordinate V of the variable memory 30, and "1" is set to the processing number n of the variable memory 30 (step S72).

Then, of the graphic data Z _{1 to} Z _C stored in the graphic data work memory 26, the center point of the n-th graphic data Z _n indicated by the value of the processing number n of the variable memory 30 is set. The graphic data changed to the coordinates indicated by the drawing coordinate V in the variable memory 30 is created (step S73), and the created graphic data is stored in the graphic data memory 16 (step S74).

Next, the value of the processing number n of the variable memory 30 is incremented by "1" (step S75), and whether the result exceeds the value of the number C of figures stored in the variable memory 30 or not. Is determined (step S76).
If it exceeds, the process is performed in step S of the upper flowchart.
8, but if it has not exceeded, search for a point on the drawn free line that is separated from the coordinate indicated by the drawing coordinate V of the variable memory 30 by the distance W, and set the new coordinate. After the drawing coordinates V are stored in the variable memory 30 (step S77), the above step S
Returning to 73, the above process is repeated.

In the above embodiment, the drawn free line is set as the region to be uniformly arranged, and the graphic contacting the free line is selected as the graphic to be uniformly arranged.
The present invention is not limited to this, and for example, a rectangular area may be designated and the figures in the rectangular area may be evenly arranged on the drawn free line. In that case, steps S1 to S4 in FIG. 2 may be changed to steps S11 to S14.
