Writing GIF and/or TIFF files correctly is non-trivial (and we don't need any more badly written files out there). Find some file converter that you like (PBM on a UN*X box works well, there are a couple for PCs and MACs (mail me if you need more specific information)), then find a simple format that the converter supports (PPM for PBM, etc.). Now you can write out files in that format and use the converter to convert to GIF/TIFF and not have to worry about getting everything right. marcos p.s. If you really want a copy of the GIF and/or TIFF specs mail me your US mail address and I will send them to you (they are available via FTP, but since I can't ftp from this site I really don't know where). -- Marcos H. Woehrmann {claris|apple}!netcom!marcos | marcos@netcom.COM Oh, I'm sure you've heard it all before, but remember it's not what you say, it's how you say it, and how much you're paid to do so, and besides who's listening anyway. No one, that's who, because it's all been said and done and done and done and done to death. Let's talk about art, said the fool to the idiot. --Lydia Lunch
