That’s most definitely not what Graham is looking for. He’s looking for a way to convert colours programatically, and cross-platform iOS and OSX (no colorsync on iOS).
I just looked in my library of bits and pieces and found some code which write into a bitmap and reads it out again. I don’t even know when I wrote that, and it’s not used in any of my projects, but I believe that was me converting colours at low-level.
Surely there’s a better way (but then again I said ‘surely there is a better way’ when I saw the discussion on whitespace in swift and there hasn’t been one yet).
