My apologies for the useless message that just went to the list....

It could be a vanilla int. Or a boost::integer::uint24_t. How about:

struct foo {
int rgb:24;
int bar:3;
int baz:4;
int alpha:1;
};


The point of your library is to interface with low-level file formats. Anything goes down there.
