Parameters

c
Type: Emgu.CV..::..Seq<(Of <(<'Point>)>)>
Pointer to the first contour
externalColor
Type: TColor
Color of the external contours
holeColor
Type: TColor
Color of internal contours (holes).
maxLevel
Type: System..::..Int32
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(maxLevel)-1 level
thickness
Type: System..::..Int32
Thickness of lines the contours are drawn with. If it is negative, the contour interiors are drawn
offset
Type: System.Drawing..::..Point
Shift all the point coordinates by the specified value. It is useful in case if the contours retrived in some image ROI and then the ROI offset needs to be taken into account during the rendering
