For the Amiga, I use WhirlGIF which is a command line routine with lots of options. I think the palette options are detailed in the manual. You can apparently select any colour as transparent, but I only managed it with white. Maybe I haven't read the manual properly. If you have a very large number of frames, the 256 character command line will fill very quickly and you run out of space. However, it will also accept an ascii term for the frame listing (I simply use 'list' following the input switch (-i), then I include a text doc called 'list' in the WhirlGIF directory. This doc is just a listing of all the frame filenames (one per line). I found WhirlGIF almost bombproof except for transparency, which is probably my fault anyway. All the animGIFs on my website were created with it (click link at bottom). Info on WhirGIF can be found
HEREOn the PeeCee, I've tried several freeware GIF animators and found them somewhat lacking and nowhere near as good as WhirlGIF. There are some good cheap ones with 1 month free trials. Tried EasyGIF amongst many others and Microsoft also do a freebee but it's quite basic.
GIF anims can only have 256 colours of course. I really needed 24-bit and PNG format could be a way to go. If you're not using them for web pages, there's an excellent PNG (24-bit) animator, which I've lost details of but a bit of Googling should find it. 24-bit PNG-anims are very nice but not a single mainstream browser supports the format. Stupid I reckon and plenty others think so too. There's even a web petition going on around it.
Cheers,
