Description

This function takes a packed color value in the correct format for the specified pixel format and extracts the red, green and blue components. Note that the color values may not be the same as when you packed them with MGL_packColor if the pixel format is a 15 or 16 bit format because of loss of precision. The values are scaled back into the normal 24 bit RGB space.
