Hello Dr.Tom,

Here is the all source code for jpeg to 3200 program:
 cjpeg(jpeg compression),djpeg(jpeg decompression to ppm file)
 ppm3200(convert ppm file to 3200 file)

I say again : it's very slow & much modification needed to speed up.
(cjpeg/djpeg are from Independent JPEG group's JPEG software v2.)

Sincerely -

Atsuhiro Suzuki

Dr. Suzuki sent this all to me several years back and after my
reviewing it closer I've come to realize there is much more to
the src. collection than I perceived before. Namely, that several
other graphic formats can be implimented. Perhaps the reader of this
can see from the list of the src. files my thoughts on this by 
reviewing them as follows'
ANSI2KNR.CC
CJPEG
CONFIG.CC
DJPEG
EGETOPT.CC
How.to.compile
JBSMOOTH.CC
JCARITH.CC
JCCOLOR.CC
JCDEFLTS.CC
JCEXPAND.CC
JCHUFF.CC
JCMAIN.CC
JCMASTER.CC
JCMCU.CC
JCONFIG.H
JCPIPE.CC
JCSAMPLE.CC
JDARITH.CC
JDCOLOR.CC
JDDEFLTS.CC
JDHUFF.CC
JDMAIN.CC
JDMCU.CC
JDPIPE.CC
JDSAMPLE.CC
JERROR.CC
JFWDDCT.CC
JINCLUDE.H
JPEGDATA.H
JQUANT1.CC
JQUANT2.CC
JRDGIF.CC
JRDJFIF.CC
JRDPPM.CC
JRDRLE.CC
JRDTARGA.CC
JREVDCT.CC

JVIRTMEM.CC
JWRGIF.CC

Perhaps, I'm in error with my interpretation of these files.
But, it seems to me conversions could also included for
the following graphic formats to the IIgs' 3200 graphic format;
gif, targa, rle, etc. I beleive Tim Meekins uses this src. and
others to develop his Image Quant program and had plans to include
most of the other graphic formats not implimented into the last
v0.30 of his Image Quant program, before he abandoned any more
updates to it.

I"m going to attempt to obtain Tim's src. code for Image Quant and
then (if I do - with his premission) release it to public review..
Perhaps with this src in this archive, along with others and the 
Image Quant src. (when and if made available) a good programmer
could develop and release as a freeware a multi-format graphics
conversion utility for the IIgs - with improved speed and optimization
that would support many of the currently missing graphic formats
to allow for a conversion to the IIgs' 3200 graphic file format.

Even though Seven Hills offers such with their commercial program:
SHR Convert v4.0, at a very reasonable price - I feel the need for 
a comparative freeware program is in order for the IIgs for those
who simply can't afford the commercial program.
