cmRGBASpace

Declaration

cmRGBASpace = cmRGBSpace + cmAlphaSpace

Discussion

An RGB color space composed of red, green, and blue color value components and an alpha channel component. ColorSync does not currently support bitmaps that use this constant alone. Instead, this constant indicates the presence of an alpha channel in combination with cmLong8ColorPacking to indicate 8-bit packing format and cmAlphaFirstPacking to indicate the position of the alpha channel as the first component.
