IFFCR and IFFL
Crunch and Show ILBM/IFF Art Files
Programs by A. J. Brouwer
----------------------------------
IFFCr will crunch an ILBM/IFF art file to about 60 to 66 percent its
original size. That's byte size, not the screen size of the art.
IFFL will display the crunched picture file.
The syntax for IFFCr as it is set up on this disk:
iffcr [sourcefilename] to [targetfilename]
You will be asked to type a crunch speed number from 1 to 9 as prelude
for the crunching work. The higher the number, the less time is taken to
crunch and the less efficient the program is. Lower numbers produce longer
crunch time and more efficiency. However, in tests we've found the
extra bytes saved are often not worth the exceedingly long time required to
crunch. So enter a 9 to start your own experiments.
IFFCr creates a newly-named crunched version and does not destroy the
old, uncrunched version.
The syntax for IFFL, which displays the compacted screen with no loss
of original quality:
iffl [filename]
It takes a while to crunch a picture, so be patient. The display
program, however, is quicker.
Be warned that a crunched file can only be shown by IFFL, so don't lose
the original file, should you wish to access it in traditional ways.
