Public Methods

Method	Description
ApplyFilter ( FastBitmap bitmap ) : void

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.

Method	Description
FilterPixelsBilinear ( FastBitmap source, FastBitmap destination, int width, int height, System.Windows.Int32Rect transformedSpace ) : void
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

public final ApplyFilter ( FastBitmap bitmap ) : void
bitmap	SoundInTheory.DynamicImage.Util.FastBitmap
return	void

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

protected abstract GetDestinationDimensions ( FastBitmap source, int &width, int &height ) : bool
source	SoundInTheory.DynamicImage.Util.FastBitmap	The source image.
width	int	The desired width of the output image.
height	int	The desired height of the output image.
return	bool

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

protected GetTransformedSpace ( System.Windows.Int32Rect rect ) : System.Windows.Int32Rect
rect	System.Windows.Int32Rect	The rectangle to transform.
return	System.Windows.Int32Rect

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

protected OnBeginApplyFilter ( FastBitmap bitmap ) : void
bitmap	SoundInTheory.DynamicImage.Util.FastBitmap
return	void

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

protected abstract TransformInverse ( int x, int y ) : Point
x	int	The X position of the pixel in the output image.
y	int	The Y position of the pixel in the output image.
return	Point
