Not precisely, although the .TNY format is, like Degas and Neo, specific
to the ST.  The Tiny format was invented by David Mumper several years
ago.  The compression algorithm is especially suited to the interleaved
bitplanes of the ST's screen memory, so Tiny format pictures are much
smaller than their uncompressed and Degas-compressed counterparts.

For a detailed description of the Tiny format, consult the Picture
Formats List, posted here periodically and archived at atari.archive.umich.edu
in atari/graphics/picfmts.doc.
