I'm looking for an app which would allow me to dither 8 bit color picts into 1 bit B/W picts . I'm using an SE/30 and need to be able to view color picts and print them on my deskwriter. Any program which allows me to dither should do the trick. Shareware would be preferred, but any pointers to commercial software would also be appreciated. Karl

It's main function is a GIF viewer/editor, but it does an excellent job with PICT/PICT2/TIFF images as well. It has adjustable dithering. Shareware $40. There was also a recent blurb in MacWeek for a new RDEV (printer driver) that will dither color images for printing on the ImageWriter II. There is a demo version floating around the BBS systems here in the Twin Cities, and (of course) I can't remember it's name! It worked adequately well on my IW II, and if you have a color ribbon, it is supposed to allow 32,000 colors via dithering. I don't know if it would work on the DeskWriter or not. -- .--------------------------------------------------------------------. | Paul Jacoby, 3M Company | Parachuting?

The only one I'm aware of if the software which comes with the MacVision Video Digitizer. It offers lots of options for dithering and can open/save PICT, TIFF, MacPaint and RIFF files. Only problem is I don't know if they sell it separately from the digitizer.... |||| Boyd Ostroff / Tech Director / SUNY Oswego Dept of Theatre / 315-341-2987 |||| Sys Admin at cboard.UUCP / Serving the Performing Arts / 315-947-6414/8N1 |||| ostroff@oswego.oswego.edu / cboard!ostroff@natasha.oswego.edu

If you are working with GIF files, you can use QuickGIF by AmariliSoft (sp?), which is shareware. You should find it at most FTP sites - it was at sumex last time I looked. Is has three different dithering methods, which seem to be quite good. Of course, if you have absolutely nothing to do with GIFs, then you can ignore me completely :-) -- See ya Nigel. ---------------------------------------------------------------------- Nigel Stanger, Internet: stanger@otago.ac.nz c/o University of Otago, P.O.

Well, since the poster said that he's using PICT files, I don't think QuickGIF is going to do the job. However, GIFConverter (current version is 2.2.6) will dither 8-bit color PICTS (and is supposed to do 24-bit, although I haven't tried it). GIFConverter is available from Sumex, and is $40 shareware. Hope this helps, --Mike
