BulkPixelConversion ( IntPtr srcBytes, int srcOffset, PixelFormat srcFormat, IntPtr dstBytes, int dstOffset, PixelFormat dstFormat, int count ) : void	Convert consecutive pixels from one format to another. No dithering or filtering is being done. Converting from RGB to luminance takes the R channel. In case the source and destination format match, just a copy is done.
BulkPixelConversion ( PixelBox src, PixelBox dst ) : void	Convert pixels from one format to another. No dithering or filtering is being done. Converting from RGB to luminance takes the R channel. The source and destination boxes must have the same dimensions. In case the source and destination format match, a plain copy is done.

PackColor ( ColorEx color, PixelFormat format, IntPtr dest ) : void	Pack a color value to memory
PackColor ( float r, float g, float b, float a, PixelFormat format, IntPtr dest ) : void	Pack a color value to memory

UnpackColor ( PixelFormat pf, IntPtr src ) : ColorEx	Unpack a color value from memory
UnpackColor ( byte &r, byte &g, byte &b, byte &a, PixelFormat pf, IntPtr src ) : void	Unpack a color value from memory This function returns the color components in 8 bit precision, this will lose precision when coming from A2R10G10B10 or floating point formats.
