C# Class WinRTXamlToolkit.Imaging.WriteableBitmapFloodFillExtensions

WriteableBitmap extensions for filling regions of the bitmap with flood fill and similar algorithms.

Public Methods

Method	Description
FloodFill ( this target, int x, int y, int outlineColor, int fillColor ) : void	Fills a region of the bitmap within an outline of outlineColor with a fillColor. This is the most simple flood fill algorithm implementation. Not the most efficient.
FloodFillReplace ( this target, int x, int y, int oldColor, int fillColor ) : void	Fills a region of the bitmap replacing the oldColor with a fillColor. This is the most simple flood fill algorithm implementation. Not the most efficient.
FloodFillScanline ( this target, int x, int y, int outlineColor, int fillColor ) : void	Fills a region of the bitmap within an outline of outlineColor with a fillColor. This is the most simple flood fill algorithm implementation. Not the most efficient.
FloodFillScanlineReplace ( this target, int x, int y, int oldColor, int fillColor ) : void	Fills a region of the bitmap replacing the oldColor with a fillColor. Improves upon the basic algorithm being about 7x faster.
FloodFillScanlineReplace ( this target, int x, int y, int oldColor, int fillColor, byte maxDiff ) : void	Fills a region of the bitmap replacing the oldColor with a fillColor. Improves upon the basic algorithm being about 7x faster.

Fills a region of the bitmap within an outline of outlineColor with a fillColor.
