Hi As discussed with Karl (below), I felt the "PNG vs GIF" tip on the W3C site was missing a mention of animation. After scratching my head about how to work that into the existing text structure, I eventually decided that a separate subsection might work best: Animation If you require simple animated images, then GIF is currently the best choice. MNG is the multi-image variant of PNG which provides the same functionality as animated GIFs. Unfortunately none of the mainstream browsers currently support the MNG format. History has now overtaken the paragraph on the LZW patent. Perhaps it could be replaced with something like this: One of the issues surrounding the GIF format is that the LZW algorithm was protected by patents held by the company Unisys. This page (http://www.unisys.com/about__unisys/lzw) on the Unisys web site confirms that their LZW patent expired in the USA on June 20, 2003 and their patents in Canada, France, Italy, Germany, the United Kingdom, and Japan, expired in July 2004. Finally, I notice that there is a 'mailto' link for www-qa@w3.org on this page ... http://www.w3.org/QA/Tips/ ... which uses a broken HREF of: maitl:www-qa@w3.org Regards Grant On Tue, 2004-05-25 at 07:04, Karl Dubost wrote: > Hi Grant, > > Le 20 mai 2004, à 21:53, Grant McLean a écrit : >> I've just read your PNG vs GIF analysis: >> >> http://www.w3.org/QA/Tips/png-gif >> >> I can't help thinking 'animation' deserves a mention :-) > > Please do send your comment to www-qa@w3.org about it and try to > develop a bit more writing a small paragraph for it.
