[comp.sys.mac.apps] JPEG

  Howdy all.

  Does anyone have a program that will do JPEG compression/decompression?

  I know that Photoshop claims to be able to; has anyone succesfully managed
to so use it?  (I tried it in Egghead the other day, and it caused PS to
exit to the finder.  Tacky.)


  Any help would be appreciated.

Eastman Kodak has a product called COLORSQUEEZ that can do JPEG
compression/decompression.  However you should know that although
there is a standard of sorts for JPEG there is not a similar
standard for a JPEG file format.  Therefore I do not think you will
be able to read the COLORSQUEEZ output into another program that
'reads' JPEG.  Fortunately COLORSQUEEZ also can read and write
TIFF and Apples own PICT formats.

Photoshop does not have JPEG built in, nor does it claim to.  I have a set
of beta software only JPEG plugins for Photoshop, written by C-Cube.  They
are a little buggy, but still work pretty well.

Storm Technology has a NuBus DSP board that comes with a set of JPEG plugins
for Photoshop.  I have seen this demo'ed, and it worked in the demo (of
course)
but can't speak for it's reliability.
