Parameters

src

Type: Emgu.CVIInputOutputArray
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.

mask

Type: Emgu.CVIInputOutputArray
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).

seedPoint

Type: System.DrawingPoint
The starting point.

newVal

Type: Emgu.CV.StructureMCvScalar
New value of repainted domain pixels.

rect

Type: System.DrawingRectangle
Output parameter set by the function to the minimum bounding rectangle of the repainted domain.

loDiff

Type: Emgu.CV.StructureMCvScalar
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

Type: Emgu.CV.StructureMCvScalar
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.

connectivity (Optional)

Type: Emgu.CV.CvEnumConnectivity
Flood fill connectivity

flags (Optional)

Type: Emgu.CV.CvEnumFloodFillType
The operation flags.
