How common are the formats' encodings ? JPEG, PNG, BMP, GIF, TGA, PPM... ?
Compressed ? With/without loss ? Not compressed ?
There are various libraries, full Ada (at least for BMP, GIF, TGA & PPM) 
or bindings, which support these usual formats. Could be a good starting 
point, and you also could use them for the "back-end" jobs.
