Description

The fg_unmaprgb() function extracts the red, green, and blue color components from an encoded 16-bit or 32-bit color value.

red receives the encoded color value's red component, between 0 and 255.

green receives the encoded color value's green component, between 0 and 255.

blue receives the encoded color value's blue component, between 0 and 255.

Return value
