I recently ftped pbmplus for my amiga and I would like to use it to convert a couple gifs into ilbms. Unfortunately, the documentation that came with pbmplus seems rather incomplete, and I am not sure if I am running it properly. From what I understand, you first run giftoppm and then run ppmtoilbm correct? I tried running giftoppm as follows: giftoppm filename.gif unfortunately, all it seemed to do is suck up most of my ram and then, after a period of thought, dump a lot of garbled stuff onto the screen. I thought perhaps that the output had to be redirected to a file, and the garbled stuff was actually supposed to be the output, so then I ran it like this: giftoppm filename.gif >filename.ppm but all it did was create a file called ">filename.ppm" and continue to dump all the garbled characters onto the screen. I haven't been able to find anywhere in any of the documentation what the command line is supposed to look like for this program. Also, I've never let it run to the end - the garbled character printing seems to go on forever. Should I just be more patient? Does it come out right in the end? Can someone please help me on how to use this program, or possibly direct me to an amiga GIF viewer/converter that is easier to use? (I have already seen GIFMachine, but its docs say it requires WB2.0 which I don't have). E-mail responses would be preferred. Ken Huisman c315-25@cs.ualberta.ca

You almost had it! The standard AmigaDOS Shell/CLI requires the i/o redirection to immediately follow the command name (under SKsh you would have been ok). Try this: giftoppm >filename.ppm filename.gif ; GIF --> PPM ppmquant <filename.ppm >filename2.ppm 32 ; reduce 256 to 32 colors ppmtoilbm <filename2.ppm >filename.iff ; PPM --> ILBM (IFF) If you're converting a 16 color GIF you can skip the "ppmquant" step. If "ppmtoilbm" finds more than 32 colors in the PPM file it will write a HAM file, which may ore may not be what you want. If you have a shell that handles pipes the way they work under Unix (SKsh and the ARP shell do), try this: giftoppm filename.gif | ppmquant 32 | ppmtoilbm >filename.iff Write yourself a script for often-used conversion to save yourself the typing! >the garbled character printing seems to go on >forever. Should I just be more patient? Does it come out right in the >end? The garbled characters are the PPM file! Try printing a .gif or an .iff file to the screen. Same thing. What PBMPLUS does is convert everything into the PPM format, manipulate that, and from there convert it to some other format. The programs are ports from Unix software and tend to be fairly memory hungry. They do a very good job, though! I hope this clarifies things and is of help to anybody else who is interested or has problems with the PBMPLUS programs. Enjoy! ._.

It's a silly feature of AmigaOS. I get around it by using Matt Dillon's CSH unix-like shell (I think v2.06). It works so well with my limited resources -- 2 FD and 1MB RAM -- that I can't give it up. Does WB2.0 improve on the redirection and pipe handler of AmigaOS at all?
