Example Illustration

missing image of CPLsubtractTL(CPL1,TL1,CPL2,TL2,buf,

Syntax

CPLN=CPLsubtractTL([CPL1,TL1,CPL2,TL2,buf,"debug"])

Input Parameter

CPL1: Contour to subtract from
TL1: path of contour 1 must have the same length of TL2 or 3x3
CPL2: Contour to be subtracted
TL2: path of contour 2 must have the same length of TL1 or 3x3
buf: buffer to increase CPL2 before start
"debug": if used the function shows results stepwise

Output Parameter

CPLN: New contour

Examples


Posesample(10); PS=ans;
