Public Methods

Method	Description
Apply ( FastBitmap dst, FastBitmap src, Rectangle rois, int startIndex, int length ) : void
Apply ( FastBitmap dst, Point dstOffset, FastBitmap src, Point srcOffset, Size roiSize ) : void
Apply ( FastBitmap dst, Point dstOffset, FastBitmap src, Point srcOffset, int scanLength ) : void
Apply ( PixelData dst, PixelData src, int length ) : void
ApplyBase ( FastBitmap dst, Point dstOffset, FastBitmap src, Point srcOffset, Size roiSize ) : void	Provides a default implementation for performing dst = F(dst, src) or F(src) over some rectangle of interest. May be slightly faster than calling the other multi-parameter Apply method, as less variables are used in the implementation, thus inducing less register pressure.
ComputeAlpha ( byte la, byte ra ) : byte	Computes alpha for r OVER l operation.
PixelOp ( ) : System

ApplyBase() public method

Provides a default implementation for performing dst = F(dst, src) or F(src) over some rectangle of interest. May be slightly faster than calling the other multi-parameter Apply method, as less variables are used in the implementation, thus inducing less register pressure.

public ApplyBase ( FastBitmap dst, Point dstOffset, FastBitmap src, Point srcOffset, Size roiSize ) : void
dst	System.Drawing.FastBitmap	The Surface to write pixels to, and from which pixels are read and used as the lhs parameter for calling the method PixelData Apply(PixelData, PixelData).
dstOffset	Point	The pixel offset that defines the upper-left of the rectangle-of-interest for the dst Surface.
src	System.Drawing.FastBitmap	The Surface to read pixels from for the rhs parameter given to the method PixelData Apply(PixelData, PixelData)b>.
srcOffset	Point	The pixel offset that defines the upper-left of the rectangle-of-interest for the src Surface.
roiSize	System.Drawing.Size	The size of the rectangles-of-interest for all Surfaces.
return	void

ComputeAlpha() public static method

Computes alpha for r OVER l operation.

public static ComputeAlpha ( byte la, byte ra ) : byte
la	byte
ra	byte
return	byte

PixelOp() public method

public PixelOp ( ) : System
return	System
