Color in Bitmaps
Windows handles colors in bitmaps differently than colors in pens, brushes,
and text. Compatible bitmaps, created by using the
CreateBitmap or
CreateCompatibleBitmap function, are device specific and retain color information in a
device-dependent format. No color values are used, and the colors are not subject to
approximations and dithering.
Device-independent bitmaps (DIBs) retain color information either as color
values or color palette indices. If color values are used, the colors are subject
to approximation, but not dithering. Color palette indices can only be used
with devices that support color palettes. Although Windows does not approximate or
dither colors identified by indices, the resulting color may be different than
that intended, because the indices yield valid results only in the context of
the color palette that was current at the time the bitmap was created. If the
palette changes, so do the colors in the bitmap.
