todays web sites shouldn't use gif images due to patent license. this patch replaces almost all references to gif images by png ones. there's only two gif animated images but I don't know how to replace them. so, I left them intact. of course, references to foreign gif images have been left intact also. in addition to this patch, gif images located in the en/gifs and en/java subdirectories needs to be converted to png ones using the following commands : cd www/en/gifs mv pbfbsd2.gif pbfbsd2.gif.tmp mv powerani.gif powerani.gif.tmp mogrify -format png *.gif rm *.gif mv pbfbsd2.gif.tmp pbfbsd2.gif mv powerani.gif.tmp powerani.gif cd www/en/java convert j2j.gif j2j.png rm j2j.gif mogrify and convert are available from the ImageMagic port.

This looks good to me. Is there any reason not to convert all of our images to PNG? - Murray

I've just seen that this patch set don't apply correctly du to the "\ No newline at end of file" in en/gallery/gallery.xsl. 2 solutions : manually delete the line "\ No newline at end of file" before to apply it or use the following script : sed '/No newline at end of file/d' < gif2png.patch | patch Cyrille. -- Cyrille Lefevre mailto:clefevre@citeweb.net
Given that the GIF patent has expired does this PR still need to be open? -- Joseph Scott http://joseph.randomnetworks.com/

I don't know, but I figured that if it was good enough for gd to bring back gif support things were ok. -- Joseph Scott http://joseph.randomnetworks.com/
State Changed From-To: open->suspended Mark as suspended until someone who really understands the patent status can comment on whether this is still needed or not.
The GNU Project has some nice proze on this topic (last updated 2005/10/31). Why no GIFs: "There are no GIFs on the GNU web site because of the patents (Unisys and IBM) covering the LZW compression algorithm which is used in making GIF files. These patents make it impossible to have free software to generate proper GIFs. [...] For more information about the GIF patent problems, see the League for Programming Freedom GIF page[1]. Through that page you can find more information about the problem of software patents in general." When will creating 'real' GIFs probably be safe: "Of the places whose patent databases we were able to search, the latest expiration date seems to be Friday 11 August 2006. Until then, anyone who releases a free program for making GIF files is likely to be sued. We don't know any reason to think that the patent owners would lose these lawsuits." This issue can be closed on Saturday 12 August 2006. How bad has who been before that?
