After a year of work new versions of GEGL<\/span>, new non-destructive image processing core, and babl, a bitmap format conversion library, are out with several major changes.<\/p>\n

The new version of GEGL<\/span> features code created during Google Summer of Code 2010 by Danny Robson and Michael Mur\u00e9. Danny Robson created GEGL<\/span> operations for loading and saving RGBE<\/span> images (HDR<\/span>), merging exposure brackets into HDR<\/span> and three tonemapping operations, as well as a matting operation. You can read more about his project here<\/a>. Michael Mur\u00e9 created a new map-absolute operations that provides pixel mapping render capability for new Cage transform tool, expected in upcoming GIMP<\/span> 2.8.<\/p>\n

Another major change is support for pluggable buffers that will assist transition of GIMP<\/span> to using GEGL<\/span> buffers directly, as well as provide means of using arbitrary buffers (think Google Maps).<\/p>\n

JPEG2000<\/span> and PPM<\/span> loaders and savers for GEGL<\/span> were contributed by Mukund Sivaraman, and some existing GIMP<\/span> filters were ported to GEGL<\/span> operations by Alexia Death, Barak Itkin and Andy Gill.<\/p>\n

The babl library has less changes, but one of the important ones is support for n-component formats.<\/p>\n

There’s still a lot of work to be done on GEGL<\/span>. \u00d8yvind Kol\u00e5s created a list of high priority tasks<\/a> that need solving. If you wish to contribute, don’t hesitate to join gegl-developer<\/a> mailing list and\/or IRC<\/span><\/a> (#gegl on irc.gimp.org) and ask around.<\/p>\n","protected":false},"excerpt":{"rendered":"
