Declaration
procedure floodFill(outMask: TIEVisionImage; startingPoint: TIEVisionPoint; loDiff: TIEVisionScalar; upDiff: TIEVisionScalar; connectivity: int32_t = 4; fixedRange: bool32 = false); safecall;
Description
Fills specified mask with a connected pixels. Connected pixels will have 255 value in the mask, 0 otherwise.
| Parameter | Description |
| outMask | Output gray scale mask |
| startingPoint | Starting pixel of source image |
| loDiff | Maximal lower brightness/color difference |
| upDiff | Maximal upper brightness/color difference |
| connectivity | Determines which neighbors of a pixel are considered |
| fixedRange | If True only the difference between the current pixel and starting pixel is considered |
