Alpha blending is a Convex Combination of two Color s allowing for Transparency effects in Computer Graphic s. The value of alpha in the color code ranges from 0.0 to 1.0, where 0.0 represents a fully transparent color, and 1.0 represents a fully opaque color.The value of the resulting color when color Value1 with an alpha value of Alpha is drawn over a background of color Value0 is given by:: ''Value'' = ''Value0''(1.0 - ''Alpha'') + ''Value1''(''Alpha'')The alpha component may be used to blend to Red , Green and Blue components equally, as in 32-bit RGBA , or, alternatively, there may be three alpha values specified corresponding to each of the Primary Color s for Spectral Color Filtering . Alpha blending is natively supported by these operating systems/GUIs:
