Syntax

public void DistTransform(
	CvArr dst,
	DistanceType distanceType,
	int maskSize,
	float[] mask
)

Public Sub DistTransform ( 
	dst As CvArr,
	distanceType As DistanceType,
	maskSize As Integer,
	mask As Single()
)

public:
void DistTransform(
	CvArr^ dst, 
	DistanceType distanceType, 
	int maskSize, 
	array<float>^ mask
)

member DistTransform : 
        dst : CvArr * 
        distanceType : DistanceType * 
        maskSize : int * 
        mask : float32[] -> unit

dst: Type: OpenCvSharpCvArr
Output image with calculated distances (32-bit floating-point, single-channel).
distanceType: Type: OpenCvSharpDistanceType
Type of distance.
maskSize: Type: SystemInt32
Size of distance transform mask; can be 3, 5 or 0. In case of CV_DIST_L1 or CV_DIST_C the parameter is forced to 3, because 3×3 mask gives the same result as 5x5 yet it is faster. When mask_size==0, a different non-approximate algorithm is used to calculate distances.
mask: Type: SystemSingle
User-defined mask in case of user-defined distance, it consists of 2 numbers (horizontal/vertical shift cost, diagonal shift cost) in case of 3x3 mask and 3 numbers (horizontal/vertical shift cost, diagonal shift cost, knight’s move cost) in case of 5x5 mask.
