Syntax

public static void DistTransform(
	CvArr src,
	CvArr dst,
	DistanceType distanceType,
	int maskSize
)

Public Shared Sub DistTransform ( 
	src As CvArr,
	dst As CvArr,
	distanceType As DistanceType,
	maskSize As Integer
)

public:
static void DistTransform(
	CvArr^ src, 
	CvArr^ dst, 
	DistanceType distanceType, 
	int maskSize
)

static member DistTransform : 
        src : CvArr * 
        dst : CvArr * 
        distanceType : DistanceType * 
        maskSize : int -> unit

src: Type: OpenCvSharpCvArr
Source 8-bit single-channel (binary) image.
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.
