Saves to j2k codestream format - bare bones as that’s all I need for now. Openjpeg supports writing a jp2 container around that to support to support colour profiles, etc. That can be added pretty easily. not by me as in crunch, sorry. Saves rgb(a) & mono(a) codestream.
Dynamic real-time quality tune, similar to jpeg save as that’s where the code came from.
j2k format & openjpeg have loads of tuning parameters that can be experimented with. Right now its super simple 0-100 which is effective but could be taken further.
Enjoy !
No time to push a merge to GIMP trunk, but that’d be cool as it’s better than current GIMP j2k plugin, compatible license & ready to roll.
If anyone available to do this, please take it from here.
To avoid duplication of work, this might already be in process.
Licensing would be the least problematic part here.
The plugin makes zero use of babl/GEGL. There is no support for metadata and color profiles. There are code style issues.
I mean, yeah, it’s nice that someone wrote this code. But without a crapton of further work, it’s basically useless and can’t be included. Nice potential of growing into another ‘GIMP developers reject patches!’ showcase though
