Nevertheless such a middleware library is a realy missed. So I hoped for it in RGBA, and, as Bob pointed out, a bit blindly.

Someone could contribute such a middleware library to the libtiff project. Probably it should be an extra (optional) library. Development of such a library is quite challenging since it needs to handle unusual (or deep) integer bit-depths, colormaps, JPEG, OJPEG, YCbCr, subsampling, floating point, and exotics like LogLUV. Support for ICC color profiles would be handy. The biggest challenge is with how to provide a useful interface for the user since the end result should be easier than using libtiff itself.

I think that GEGL and Adobe GIL make a step in the right direction. Though, it is not easy to use these software. But presented approach is quite flexible and powerful.
