Regarding APNG, Mozilla developers proposed it for inclusion in libpng, but got laughed out of the PNG group. The sole maintainer of the libpng APNG patches decided to stop working on it last year. Browser support for APNG is limited to Opera and Mozilla based browsers (except Debian Iceweasel and other Linux distros that build against system libpng instead of the Mozilla internal one).
Application support for MNG seems more widespread than APNG. Browser support is worse, although contrary to what has been claimed, Konqueror is a modern browser which supports MNG.
Probably because those patents expired before Firefox had its first release.
Tell me.. Why bother having a Jpeg 2000 format if no one uses it? This should have been done AGES ago...
I thought the image format wars were over about 10 years ago...
and what advantages does it have over PNG?
just use konqueror people. Firefox is badly ported windows software anyway.
About patents: submarine patents are a problem everywhere. This can only be changed, if the us patent office would finally wake up and ban/nullify all software related patents.
everywhere corrupt politicians try to introduce software patents - despite the fact that it is toxic for all and every kind of advancement![]()
Yes, I know what Mozilla is, but I assumed he was only talking about Firefox, since back in the Netscape days, they could have easily had a license for GIF, and not enough people used vanilla Mozilla back in the day to make it a worthwhile target to sue. Plus, GIF was a lot more widespread back then than JPEG2000 is now, making it more important to support.
Or maybe the guy who developed JPEG2000 drove over one of the Mozilla developer's cats, who knows?
Firefox 2 with its weird slow GTK emulation sucked harder than Konqueror did. It's a shame Konqueror hasn't done much since then, if it had an extension API (preferably not limited to JS) I'd use it.
