Thanks, I'll give that a shot.

Compression (even lossless compression) is highly undesirable in my specific 
application.  The output images get loaded into OpenGL textures straight from 
the mmap'ed files, so for simplicity they must be uncompressed on disk.  PPM 
and PGM work perfectly for this.  Plus they behave as simple 2D arrays, which 
makes it possible to use GL_UNPACK_SKIP_PIXELS, GL_UNPACK_SKIP_ROWS, etc. to 
load subsets of a large image file.
