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 Added on 7/10/98 by Charles T. 'Dr. Tom' Turley 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 JREVDCT2.CC JUTILS.CC JVERSION.H JVIRTMEM.CC JWRGIF.CC JWRJFIF.CC JWRPPM.CC JWRRLE.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.
