Parameters

src: IntPtr
Input 1- or 3-channel, 8-bit or floating-point image. It is modified by the function unless CV_FLOODFILL_MASK_ONLY flag is set.

seedPoint: Point
The starting point.

newVal: MCvScalar
New value of repainted domain pixels.

loDiff: MCvScalar
Maximal lower brightness/color difference between the currently observed pixel and one of its neighbor belong to the component or seed pixel to add the pixel to component. In case of 8-bit color images it is packed value.

upDiff: MCvScalar
Maximal upper brightness/color difference between the currently observed pixel and one of its neighbor belong to the component or seed pixel to add the pixel to component. In case of 8-bit color images it is packed value.

comp: MCvConnectedComp%
Pointer to structure the function fills with the information about the repainted domain.

connectivity: CONNECTIVITY
The connectivity of flood fill

flags: FLOODFILL_FLAG
The flood fill types

mask: IntPtr
Operation mask, should be singe-channel 8-bit image, 2 pixels wider and 2 pixels taller than image. If not IntPtr.Zero, the function uses and updates the mask, so user takes responsibility of initializing mask content. Floodfilling can't 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. Or it is possible to use the same mask in multiple calls to the function to make sure the filled area do not overlap. Note: because mask is larger than the filled image, pixel in mask that corresponds to (x,y) pixel in image will have coordinates (x+1,y+1).
