Would anyone happen to have a description of the format digiview saves it's pictures in? I'd like to make three primary color scans, each at the 32 level setting, then combine them into an image on a color workstation display using ALL of the information (15bits, 5 per color). If anyone happens to have a Unix program that can read and make sense of a digiview file it would be very helpful. Also, has anyone tried to get a Digiview to work on non-Amiga computers? I suspect it would not be that hard if the computer happened to have a PC compatable parallel port or something like it.

If you have version 2.0 then pages 20-21 will tell you what you need to know. Don't have version 2.0??? GET IT!!! YOU'LL WANT IT!!! I think upgrading used to cost $10 - call NewTek to be sure. With it you can make the three primary color scans and save EACH at 7-bits per pixel per color. Yes, Digi-View internally stores the digitized image at 7-bits per color in RGB mode and converts this to the given display mode depth (number of colors). Now, once you've saved off your 21-bit image you can upload it to your favorite color workstation, filter it with a simple [pick your language] program to get the right # of bit planes, and display it. A friend and I used to do this at SMU with my Digi-View and the university's graphics equipment. If you have Version 2.0 then the file formats are described in the back of the manual. >If anyone happens to have a Unix program that can read and make sense >of a digiview file it would be very helpful. If you can't write one from the manual let me know and I'll see about getting a copy of what we used at SMU. Chuck McManis(sp?) at Sun wrote an article for BYTE a while backa about simple image processing on the Amiga. Check it out!! >Also, has anyone tried to get a Digiview to work on non-Amiga computers? >I suspect it would not be that hard if the computer happened to have a >PC compatable parallel port or something like it. T'would be a bit more difficult than that. You've got timing and other cruft to figure out as well. You need to be able to READ from a parallel port.... that is usually used for WRITING. It would help if the circuit in that little white sealed box was available.... I digress....

Once you have digitized an image, press the F2 key and digiview will save the image in a "dump file", 3 bytes per pixel (one each for RGB), 7 significant bits per byte (LSB undefined). It dumps the entire red plane, then the green plane, and then the blue plane. There are an additional three 32-bit words tacked on to the end of the file that you can ignore. >Also, has anyone tried to get a Digiview to work on non-Amiga computers? >I suspect it would not be that hard if the computer happened to have a >PC compatable parallel port or something like it. I have successfully created RGB dump on the Amiga, transfered them to a Mac-II, and run some appropriate software magic on the Mac-II end to turn them into displayable 256 color pics. I did not write the Mac-II software, but I worked closely with the author while it was developed last year. As far as actually running Digiview on a non-Amiga computer, I don't know of anyone that has done this. By the way, my opinion, and the opinion of everyone that I have shown the pictures to, is that the pictures on the Mac-II look better in 256 colors than the same pictures on the Amiga in 4096 color HAM mode. I can't wait to see the same pictures on the Mac-II in 24-bit color... -Fred -- # Fred Fish hao!noao!mcdsun!fnf (602) 438-3614 # Motorola Computer Division, 2900 S. Diablo Way, Tempe, Az 85282 USA
