Looks like that the openjpeg project is dead upstream, leaving us with no maintained free software JPEG2000 support (Jasper already died much earlier). I hope Artifex (upstream of Ghostscript) will kick in here.
If not, anyone volunteering is welcome. For now we must consider Ghostscript providing its own internal JPEG2000 support. See IRC chat with GS developers: <tkamppeter> chrisl, I switched back to built-in openjpeg, as I did not get it working with the system's library (GS simply built without openjpeg, without reporting any error). <chrisl> tkamppeter: it might fallback to Jasper, or might just disable JPX, I can't remember off the top of my head. <tkamppeter> chrisl, seems that openjpeg is of a rather bad coding quality: https://bugs.launchpad.net/ubuntu/+source/openjpeg/+bug/711061, especially comment #19. Are the enhancements of the GS developers (which upstream is ignoring/rejecting?) fixing these problems? <kens> tkamppeter : the 2.0 patches have not yet been submitted upstream I was incorrect in that. The developer is waiting until we adopt them ourselves I believe (at least the ones relating to GS code anyway) <kens> I think a lot of the criticisms in comment #19 are irrelvant to its use in Ghostscript <chrisl> kens, tkamppeter: actually, he's waiting for responses (of any kind!) from the openjpeg devs..... they've gone dark again :-( <kens> tkamppeter : when it comes to JPEG2000 support we have a choice of JasPer or OpenJPEG. JasPer is terribly badly written, does not support all features, and is no longer maintained. OpenJPEG may not be ideal, but we htink its better than JasPer on all points. <chrisl> tkamppeter: henrys has already suggested we "really" fork openjpeg for our use, since the project seems decidedly moribund now :-( kens is disappointed to hear that <chrisl> Well, I think Shelly's been waiting ~3 weeks for a reply to a simple question, and not even had an acknowledgement from the dev team <kens> Great, 2 open source implementations, both dead :-( <chrisl> I still have the feeling that OPJPG devs had their own requirements, and once those were met, they've backed off. I could wrong though <tkamppeter> chrisl, so I think, to get solid JPEG2000 support into Linux/free software it would be really the best if Artifex forks libopenjpeg and makes it available as separate free software project. <kens> Umm, I'm not sure we have the resources to support a 'proper' OpenJPEG library <chrisl> tkamppeter: the trouble is it's a *lot* of work..... <chrisl> tkamppeter: we might be able to "manage" the project, host the repo etc, but the development load would probably be more that we could handle -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/711061 Title: [MIR] libopenjpeg2 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/openjpeg/+bug/711061/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
