I've uploaded the files from usenet to the Mac. You must save them to a unix machine, manually strip out the header and footer, give them a name _different_ from the name in the "begin xxx.gif" line, run uuexpand on them. Take the resulting .gif files, and send them to the Mac using some binary file transfer. I use "macput -d xxx.gif" to talk to MacTerminal set up for Mac-to-mac communication. (Macput is available in C source from the machine sumex-aim.stanford.edu login: anonymous password: anonymous cd <info-mac> (the angle brackets are part of the name.) I got the GIF reader from the same source, and the archived GIF pictures. The StarTrek images are really disappointing: grainy, redish tinged, and only 16 shades. It is kind of amusing to take these, which were obviously full-screen images on the machine for which they were originally intended, but only postcard size on a MacII, and put them all on your screen at once. The images archived with GIF are slightly better: 256 colors, only a very slight reddish tinge. They are all faces from playboy centerfolds. (Not the good bits.) With a 19" display, you can get all 1 of these on your screen at once. Fun to watch the palette manager at work, as each time you click on a new window its palette takes over, and all the other windows get redrawn, with color quickdraw doing its best with the new palette. I wrote the scanner software that produced the color image of a red flower in the April issue of MacWorld. Our scanner produces 6Meg of data for each image: 1500x1024x24bits_per_pixel. I may post a GIF image of that, but it sort of blows GIF out of the water. The scanner costs $8.5k.

The scanner costs >$8.5k. ^^^^^ Probably most of the 256 color images you currently find in GIF format are images that were originally digitized in 640 x 480 x 21 bits_per_pixel on a Commodore Amiga and run through a special program to map the 21 bit color images to 8 bit color images. Cost of DigiView for the Amiga? $149.95 (list). So, divide the image dimensions and colors per gun by 2 (approximately) and save a few bucks. :-) -Fred ><> -- # Fred Fish hao!noao!mcdsun!fishpond!fnf (602) 921-1113 # Ye Olde Fishpond, 1346 West 10th Place, Tempe, AZ 85281 USA
