MatFloodFill Method (InputOutputArray, Point, Scalar)

public int FloodFill(
	InputOutputArray mask,
	Point seedPoint,
	Scalar newVal
)

Public Function FloodFill ( 
	mask As InputOutputArray,
	seedPoint As Point,
	newVal As Scalar
) As Integer

public:
int FloodFill(
	InputOutputArray^ mask, 
	Point seedPoint, 
	Scalar newVal
)

member FloodFill : 
        mask : InputOutputArray * 
        seedPoint : Point * 
        newVal : Scalar -> int 

function FloodFill(mask, seedPoint, newVal);

Parameters

mask

Type: OpenCvSharpInputOutputArray
(For the second function only) Operation mask that should be a single-channel 8-bit image, 2 pixels wider and 2 pixels taller. The function uses and updates the mask, so you take responsibility of initializing the mask content. Flood-filling cannot go across non-zero pixels in the mask. For example, an edge detector output can be used as a mask to stop filling at edges. It is possible to use the same mask in multiple calls to the function to make sure the filled area does not overlap.

seedPoint

Type: OpenCvSharpPoint
Starting point.

newVal

Type: OpenCvSharpScalar
New value of the repainted domain pixels.
