Ok everyone....
Why does a GIF File only take a few seconds to pop up on a 286 when
my GS takes up to an hour using SHRConvert?
Is there a faster GIF/converter out there????

There is of course the difference in computational speeds between the 65816 and the 80286 CPU's. I also suspect the '286 having more registers and a 32-bit data path might have something to do with it as well. Maybe the GIF decoding algorithm has been optimized to run on Intel's instruction set. Try Jonah Stich's GIF.3200 converter. It will process a 320x200 GIF in under 30 seconds on an unaccelerated GS. It's much better than SHRConvert, and it is also shareware. You might want to check out SuperConvert, but I have yet to hear anyone's comments on it. > "What do you mean we ran out of gas?" ______-==-______ > ____-------=----------------=-------____ > ________________ _ _- --------________________-------- > (______________(_||_) _______ / > /_____/_____ _- > Capt Ken Haynes \__________- > CO, USS L'Hopital > Taylor Series Class Starship > NCC-x^ln(1701) United Federation of Calculus Haters > haynes@unssun.unr.edu or haynes@tahoe.unr.edu :-) :-) :-) I love your sig!

Ken,
Try using Jonah Stich's GIF3200 program. It is faster and has
several options for converting (ie grey scale, pre or post
decrypt assignment of color table, convertion to 3200 color pics,
and scaling of oversized images. I got my copy from America Online.

Maybe the GIF >decoding algorithm has been optimized to run on Intel's instruction set. First of all, it is fairly likely that these '286 systems are running at 12 mhz or so. Second, the 286 does not have a 32 bit data bus, it has a 16 bit bus, which is still an advantage. The real reason is that there are GIF decoders for the intel CPUs that were written by total assembly jocks and as such scream the picture onto the screen. Over Christmas break I will rewrite my GIF project so that it can be used as a general pupose GIF decoder. We will then see just how fast or slow the //gs can do GIF files. See you then.

Hmmm, I was positive the 80x86 CPU's all had 32-bit data paths... we sure could use a quick GIF decoder (and encoder) for slide shows and other GIF viewers. Jonah's GIF.3200 clocks in at around 15 seconds for a 320x200x256 GIF on an unaccelerated GS. That blows away SHRConvert 2.1, but it can be faster yet. > Over Christmas break I will rewrite my GIF project so that it can be used as > a general pupose GIF decoder.

Jonah's current version of GIF.3200 is really fast, but it will only work with 320x200 pictures. If your GIFs take up to an hour with SHRConvert, I'm pretty sure that they're larger than 320x200 . >\/\/\/\/\/\/\/\/\/ | Brian T.

Just set the x and y offsets correctly.

The current version is 0.2, and it handles bigger than 320x200 fine, but there are restrictions (you can't scroll around in the picture, you have to choose the viewing window in advance).

Could someone post Jonah's GIF 3200 v0.2 to Apple2-L? I v0.1 a couple of months ago from there but have no way of getting it otherwise. Thanks ---------------------------------------- Michael J. Quinn University of Tennessee at Chattanooga BITNET-- mquinn@utcvm pro-line-- mquinn@pro-gsplus.cts.com

Yes, and now GIF3200 v0.2 is up on tybalt.caltech.edu under pub/apple2/*.
