Syntax
public void DrawContours( CvSeq<CvPoint> contour, CvScalar externalColor, CvScalar holeColor, int maxLevel )
Parameters
- contour
- Type: OpenCvSharpCvSeqCvPoint
Reference to the first contour. - externalColor
- Type: OpenCvSharpCvScalar
Color of the external contours. - holeColor
- Type: OpenCvSharpCvScalar
Color of internal contours (holes). - maxLevel
- Type: SystemInt32
Maximal level for drawn contours. If 0, only contour is drawn. If 1, the contour and all contours after it on the same level are drawn. If 2, all contours after and all contours one level below the contours are drawn, etc. If the value is negative, the function does not draw the contours following after contour but draws child contours of contour up to abs(max_level)-1 level.
