Contour(API)

DataExpress/Contourは境界線を算出するためのAPI です。psFile(API)などで使用しています。

API

search contour lines in a boxel

extern void createContourALine(contourLine* ls, contourArgs c);

create contour lines in order

extern void createContourLine (contourLines*  ls, contourLine* l);

craete contourLines at each section

extern void createContourLines(contourLines* ls, contourImage image);

create contourLines at all sections

extern void createContour(contourLinesSet* lsset, contourImage image, contourParaTypeReal level, contourFlag flag);
