Public Methods

Method Description
ApplyFilter ( FastBitmap bitmap ) : void

Protected Methods

Method Description
GetDestinationDimensions ( FastBitmap source, int &width, int &height ) : bool

When overridden in a derived class, returns the dimensions of the output image.

GetTransformedSpace ( System.Windows.Int32Rect rect ) : System.Windows.Int32Rect

Forward transform a rectangle. Used to determine the size of the output image.

OnBeginApplyFilter ( FastBitmap bitmap ) : void

This method allows derived classes to perform actions prior to the filter being applied.

TransformInverse ( int x, int y ) : Point

Inverse transform a point. This method needs to be overriden by all subclasses.

Private Methods

FilterPixelsNearestNeighbor ( FastBitmap source, FastBitmap destination, int width, int height, System.Windows.Int32Rect transformedSpace ) : void
GetPixel ( FastBitmap bitmap, int x, int y, int width, int height ) : System.Color
