This might indeed be useful at some point, but right now I do not think the GEGL architecture is flexible enough to warrant compilation and installation by default. Thus I will drop this .c file into the workshop directory where various works in progress reside. It is possible to write specialized ops that would read the RGBA u16 and output the required file. (Using R'G'B'A u16) would probably give slightly better results assuming the displays and data involved are roughly sRGB data. A plan for supporting "pallettized" images is forming somwhere on the horizon for GEGL. It would probably involve a specialized babl format and the ability to attache a floating point RGBA pallette to the format. Another similar issue for babl is that it isn't currently capable of generating pixels for formats where the components are not a multiple of 8, it is due to these short comings in GEGL I've placed color-reduction in the workshop for now. For some ramblings about indexed/palettized images take a look at: http://codecave.org/?weblog_id=indexed_metamers /Øyvind K. -- «The future is already here.
