    Default Ubuntu's Firefox May Gain JPEG 2000 Support

    Phoronix: Ubuntu's Firefox May Gain JPEG 2000 Support

    JPEG 2000, the image file format that has been around for nearly a decade and offers better compression performance and greater flexibility in the code-stream that can allow for higher quality photographs compared to a traditional JPEG, may get a boost on the Linux desktop. JPEG 2000 hasn't seen much adoption in large part because of the lack of web browsers that natively support this JP2 ISO standard, including Firefox...

    Does other OS software like GIMP and co support JPEG 2000 too? Who needs JPEG 2000?

    All major open source image viewers/editors support JPEG 2000. For GIMP there exists a plugin (which will be included by default in GIMP 2.8).

    I hope that Ubuntu will also consider adding MNG support to Firefox, which was removed by Mozilla in favour of their ill-fated APNG standard.

    I can honestly say that this isn't exactly news that gets my heart running a little faster, it simply isn't important enough to me.
    And if it is patent-encumbered (why else would Mozilla be sued if they implemented support for it in FF?), I'm only leaning more towards saying "thanks, but no thanks", especially since it isn't THAT greatly used.

    NASA likes to release big images from Mars in JPEG2000.

    It's worth noting that Konqueror started supporting JPEG2000 in 2006 or even earlier.

    Default obligatory "screw you pavlov" post

    AFAIK, Konqueror supports everything KDE itself does - which includes JPEG2k and MNG.

    Last time I tried the GIMP plugin for MNG it was half-finished and pretty crap. The part I'm more interested in is JNG (JPEG compression + alpha transparency).

    This APNG format is complete and utter garbage. I haven't seen a single app that actually supports reading it besides Firefox, never mind creating them. That makes it about as "Portable" as VML.
    It only exists at all because one particular Mozilla developer is an awful troll, and his plan to kill off MNG in Mozilla - by setting impossibly tight library size requirements - backfired spectacularly; the MNG devs almost managed it before the rug was pulled out from under them. Go check out bug 18574 on bugzilla for the complete circus. It's a glimpse into the infantile politics that go on in Mozilla's inner circles.

    The story of the MNG limbo in Mozilla is indeed a very sad one. It is notable that converting the animated GIFs which Firefox ships (for throbbers etc.) to MNG would actually reduce its size even if you count the additional code for MNG support.

    Regarding JPEG 2000, it has some advantages over JPEG, eg. alpha transparency. The Wikipeda article has all details.

    Wow, I actually had no idea it could do that.

    Kind of funny that Mozilla are worried about patents in JPEG 2000. I don't remember seeing them rushing to remove animated GIF support when Unisys started suing people left and right.

    Probably because those patents expired before Firefox had its first release.
