Horman/!Compress/!Help

This website contains an archive of files for the Acorn Electron, BBC Micro, Acorn Archimedes, Commodore 16 and Commodore 64 computers, which Dominic Ford has rescued from his private collection of floppy disks and cassettes.

Some of these files were originally commercial releases in the 1980s and 1990s, but they are now widely available online. I assume that copyright over them is no longer being asserted. If you own the copyright and would like files to be removed, please contact me.

Introduction
~~~~~~~~~~~~
Compressor is an application specifically written to be used in conjuction
with Stereo. Because of the 160k taken up by each autostereogram map, this
program will compress any sprite which contains colours in long 'strings'.
This means that autostereograms are probably the only sprites that will
benefit from this type of compression.

Compression
~~~~~~~~~~~
Drag your stereogram map on to the Compressor icon. The compressed file will
then be saved in place of the original file.

Decompression
~~~~~~~~~~~~~
To recover the original sprite, drag the compressed file back on to the
Compressor icon. Disc space permitting, the decompressed sprite should be
saved under the same name.

If you create any interesting autostereograms, animations, or have
suggestions for improvement, send them to :
