If you are going to use such functionality from a higher level programming language a future migration should be easy. At the moment I've been mainly focusing on high quality, rather than high speed and thus implemented most of the image processing only for floating point buffers. The system is designed to allow for optimizations in the form of adding 8bit/16bit versions of operations alongside the floating point versions. My intention is to port my abstractions on top of gggl to GEGL, and thus my tool chain from gggl to GEGL, after that porting the operations is one of my priorities. Depending on how urgent your needs are,. if you have some time to spend helping out with GEGL development in the near future, that would also be greatly appreciated. -- Web : http://pippin.gimp.org/ .--------------------------------- Mobile : (+47) 97 62 81 98 | Software patents hinder progress Office : (+47) 61 13 52 07 | http://swpat.ffii.org/
