Метод	Описание
Apply ( ColorBgra dst, ColorBgra src, int length ) : void
Apply ( ImageSurface dst, Gdk dstOffset, ImageSurface src, Gdk srcOffset, Gdk roiSize ) : void
Apply ( ImageSurface dst, Gdk dstOffset, ImageSurface src, Gdk srcOffset, int scanLength ) : void
Apply ( ImageSurface dst, ImageSurface src, Gdk rois, int startIndex, int length ) : void
ApplyBase ( ImageSurface dst, Gdk dstOffset, ImageSurface src, Gdk srcOffset, Gdk 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() публичный Метод

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 ( ImageSurface dst, Gdk dstOffset, ImageSurface src, Gdk srcOffset, Gdk roiSize ) : void
dst	Cairo.ImageSurface	The Surface to write pixels to, and from which pixels are read and used as the lhs parameter for calling the method ColorBgra Apply(ColorBgra, ColorBgra).
dstOffset	Gdk	The pixel offset that defines the upper-left of the rectangle-of-interest for the dst Surface.
src	Cairo.ImageSurface	The Surface to read pixels from for the rhs parameter given to the method ColorBgra Apply(ColorBgra, ColorBgra)b>.
srcOffset	Gdk	The pixel offset that defines the upper-left of the rectangle-of-interest for the src Surface.
roiSize	Gdk	The size of the rectangles-of-interest for all Surfaces.
Результат	void

ComputeAlpha() публичный статический Метод

Computes alpha for r OVER l operation.

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

PixelOp() публичный Метод

public PixelOp ( ) : System
Результат	System
