CompuShow

Version 9.04, Bob Berry.[24] Conversion capabilities; gamma support; progressive display of interlaced images. Related software includes CompuShow 2000.

[24] Contrary to the claim in the first edition of this book, Bob was not the inventor of the GIF image format, so one should not consider him the grandfather of PNG. (It's good to keep these things straight.)
