• rgbaColor& is the 32-bit RGBA color value to retrieve the red component intensity value from.
• RGBA color values are returned by the _PALETTECOLOR (function), POINT, _RGB, _RGB32, _RGBA or _RGBA32 functions.
• LONG intensity values returned range from 0 (no intensity, not present) to 255 (full intensity).

• See the example in POINT.
