Abstract
A method for drawing a composite figure by combining a plurality of figures. The contours of the plurality of figures are first drawn, and thereafter the insides of the contours are successively filled with in accordance with plane filling attributes of the corresponding figures. Thus, a composite figure with unnecessary contours made to disappear at superposed portions of the figures can be obtained.
Claims6
A method for drawing a composite figure by means of an information processing device comprising a central processing unit (CPU), a storage device storing at least an operation program of said CPU and figure data and an output device for outputting figure data, comprising the steps of:
- extracting part of data defining at least contour attributes which is relative to a plurality of figures to be composed;
- successively drawing contours of said plurality of figures in accordance with said contour attributes;
- extracting part of data defining at least plane filling attributes of said data relative to said plurality of figures to be composed;
- successively filling the insides of said contours of said plurality of figures with one of a pattern, color, or both in accordance with the corresponding plane filling attributes thereof;
- and
- suppressing a part of said contours which divide a region comprising at least two of said plurality of figures having the same said one of a predetermined pattern, color or both.
