cvDrawContours

Draws contour outlines or filled contours.

	Name	Type	Range	Description
	inImage	Image		Input image.
	inContours	Path Array		All the input contours.
	inContourIdx	Integer	-1 -	Parameter indicating a contour to draw. If it is negative, all the contours are drawn.
	inColor	Pixel		Color of the contours.
	inThickness	Integer	1 -	Thickness of lines the contours are drawn with. If it is negative, the contour interiors are drawn.
	inLineType	RegionConnectivity		Line connectivity.
	inHierarchy	Integer Array Array *		Optional information about hierarchy. It is only needed if you want to draw only some of the contours.
	inMaxLevel	Integer		Maximal level for drawn contours. If it is 0, only the specified contour is drawn. If it is 1, the function draws the contour(s) and all the nested contours. If it is 2, the function draws the contours, all the nested contours, all the nested-to-nested contours, and so on. This parameter is only taken into account when there is hierarchy available.
	inOffset	Location *		Contour shift parameter.
	outImage	Image		Output image.

Errors

This filter can throw an exception to report error. Read how to deal with errors here: Error Handling

Error type	Description
DomainError	inContourIdx is greater than number of contours in cvDrawContours.
DomainError	Number of elements in inHierarchy must be the same as in inContours in cvDrawContours.
DomainError	Each array in inHierarchy must be an array made from 4 elements.

Complexity Level

This filter is available on Basic Complexity Level.
