Describes uncompressed RGB data. The data is in
interleaved form. RGB components can be packed into
a short or an int. If the pixel components are packed, then the
redMask
, greenMask
and blueMask
fields
specify the bit masks, otherwise
they specify the order of arrangement of the components. For example:
