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.
