Does anyone know of a public domain library of routines for manipulating
various bitmap formats? I am primarily interested in group 3, group 4
and ODA bitmap formats.

As long as I am asking, does anyone have a list of ISO and ANSI
"standard" bitmap formats? The three above are obvious candidates, but
are there others buried in other standards? For example, I would not be
surprised to find a other bitmap formats defined inside of IGES (sp?) or
CGM. I also have a vague memory that the Navy came up with their own
standard bitmap format as part of Navy DIF. Are there others? 

(We are trying to put together a portable library of bitmap
manipulating/conversion routines. To that end, we would like to avoid
reinventing the wheel and to make sure that we have covered a wide
enough space to be interesting. We know about the "Portable Bitmap
Package", but that seems to concentrate on vendor formats like MacPaint,
X.11 and Suntools, rather than on ISO or ANSI standard formats.)
