Method Description
BgraToUInt32 ( byte b, byte g, byte r, byte a ) : UInt32

Packs color and alpha values into a 32-bit integer.

Blend ( ColorBgra ca, ColorBgra cb, byte cbAlpha ) : ColorBgra

Smoothly blends between two colors.
Blend ( ColorBgra colors, int count ) : ColorBgra

Smoothly blends the given colors together, assuming equal weighting for each one.

Blends four colors together based on the given weight values.

The weights should be 16-bit fixed point numbers that add up to 65536 ("1.0"). 4W16IP means "4 colors, weights, 16-bit integer precision"

Blends the colors based on the given weight values.

"WAIP" stands for "weights, arbitrary integer precision"

Blends the colors based on the given weight values.

"WAIP" stands for "weights, floating-point"

ClampToByte ( double x ) : byte
