Hi, my name is Jan and I am a student of the University of West Bohemia in the Czech Republic. This year I am writing my bachelors work - a program for advanced color correction. GEGL we found very useful library. But our target is a program that will also work with images in color spaces other than RGBA. So I have some questions about color spaces and bit depths: 1) Oftentimes you write that most operations work in the RGBA color space. If I understand correctly, GEGL care about the transfer to the native color space (format) in the "prepare" (such as in operation "brightness-contrast"). In GEGL are some operations that are not limited to RGBA as "invert"(at least contains no "prepare"). Although there is no conversion to native RGBA, but this operation algorithm uses three channels, which inverts and one that is not inverted. So it would work properly with RGBA (but not in CMYK), how to ensure that this format will be the input? (is there any other mechanism which automaticaly converts formats to RGBA than "prepare"?) 2) What color spaces and bit depths GEGL buffer supports? They are all that are defined in the BABL? Thank you in advance for the valuable information!
