This was taken from devdraw.c:

/**
 * Draw a color bitmap image in 1, 4, 8, 24 or 32 bits per pixel.  The
 * Microwindows color image format is DWORD padded bytes, with
 * the upper bits corresponding to the left side (identical to
 * the MS Windows format).  This format is currently different
 * than the MWIMAGEBITS format, which uses word-padded bits
 * for monochrome display only, where the upper bits in the word
 * correspond with the left side.
**/

What happened to 16bpp?

> There is one thing that's bugging me and although I not sitting infont of
the source, I think the names are pretty close if ot exact. What's the
difference between RGB2PIXEL and COLORVAL2PIXELVAL? I could see where
RGB2PIXELVAL comes in, but COLORVAL2PIXELVAL? They seem to be saying the
same thing to me.

The two act the same when microwindows is compiled for a 32-bit
pixel size, MWPF_TRUECOLOR0888, which is the default. They
change when a COLORVAL is 8 or 16 bits in length. Study the
config file and the source for more details.

Regards,

Greg
