i need some help. i heard somewhere that .gif files can be viewed on an apple if the right software is used if this is true can someone tell me what or where this software is? i know .gif files are mainly (or all) ibm pictures, but is there truth in any of what i have heard? adios page@pro-party ---- ProLine: page@pro-party Internet: page@pro-party.cts.com UUCP: crash!pro-party!page ARPA: crash!pro-party!page@nosc.mil

Actually, .gif files are for any computer, as the name implies (graphics *interchange* format). The file you need is "//gif", and I believe is a public domain program. Check local bulletin boards.

On an apple//e you need IIGIF to view .gif files. There are several programs that allow .gif viewing on a IIgs (which someone else will have to tell you about because I use a //e). You can probably get IIGIF and its dox from apple2.archive.umich.edu. If you have problems let me know and I will send it to you. You need binscii and shrinkit. -- Bill Carss bill@braille.uwo.ca

No, the GIF file format is supposed to be the same across systems. What you probably encountered was a stupid "MacBinary" header that people often add when uploading Macintosh files to other systems, on the assumption that it is important to restore the file attributes when the file is downloaded to another Macintosh. They really ought not to do this when uploading GIF files.

(heh) I believe only MAC GIFs have a special header (128 byte?) on them.. And I would bet that there are some Mac GIF creators that don't have the header, but the header is associated with Macs, not all Apples in general (i.e. Apple // and Mac). -- /unknown@ucscb.ucsc.edu Apple IIGS Forever! unknown@cats.ucsc.edu\ |WANT to help get ULTIMA VI //e or GS written?-mail me.

So you are able to view GIF files that you can view in a PC/Unix/Amiga (eg. from wuarchive)(biggests gif site I've ever found) in IIGIF? When I tried doing that, I get garbage. But when I view GIF files I grab from Apple sites, it works. In fact, I remember now. There was a program I had to use (STRIPGIF, you can download it from the msdos/gif directory in Simtel20 or Wuarchive) to strip the extra header off of Apple gif files before you can view it on a PC/Unix. It worked too but since it was such a hassle, I just ended up having two sets of gif files. Maybe that was the Mac gif format, but I had to use this "Apple" gif format before IIGIF can read it. PC gif files displays garbage. Is there a new version of IIGIF out that can accept non "apple" gif files nowadays? Grab a gif file from wuarchive.wustl.edu in the directory graphics/gif. It has so many files that they're separated by the first letter of their filename in separate directories. So directory a/ contains files starting with 'a' and b/ with 'b'....etc. Just grab any file and see if you can view it under IIGIF. Or if you already have a gif from a PC hanging around somewhere, see if you can view it under IIGIF. Maybe I don't have the latest version. Thomas.

It was around $20 I'm not trying to knock SuperConvert, but if you don't want to wait EONS for your GIF files to be shown, get Jonah Stitch's GIF3200 or wait {hopefully not long --TODD?} for LordHighGiffer. Both are HELLA fast, and I would say they come close to being as fast as IBM or Mac GIF viewers. They have varying qualities to select from to convert with, and obviously the higher quality the less time, but even on the BEST quality on both, they are possibly ORDERS OF MAGNITUDE faster than SuperConvert.

Sorry - I have well over 60 double-sided 5.25" disks full of GIFs that disagree with you. Admitted, they don't always come out well - but that's more a function of the limited colors and resolution of the II than anything else. ---- ProLine: rhood@pro-gsplus | "Wherever you go...there you are."

I tend to think Jonah's program is a bit slow without an accelerator (for a decent convert). I hear there is an accessory disk which you use with SuperConvert which speeds up the conversion and/or has better color optimization. These may not necesarily be written by Jason Harper. Another good program to use (judging by the results) is a program called Prizm. > Both are HELLA fast, and I would say they come close to being as >fast as IBM or Mac GIF viewers.

BTW, I have found a few GIFs where Median Cut 3200 produces much WORSE ouput than "normal" conversions. These are few, but I am curious as to why this would happen at all. Also I have a couple of GIFs that are not as good on the IBM VGA as the Apple 3200 mode, weird but true. UUCP: bkj386!pnet91!ericmcg INET: ericmcg@pnet91.cts.com

Does anyone know how the median-cut algorithm for color selection works? _Please_ tell me; I've looked through Wilson Disc at the library and it did not come up with anything. I can understand, pseudo-code, C, Pascal, Basic, Fortran, even assembly if you have source code. I've been wondering how it works & can't figure it out.
