Extract embedded ICC color profiles from files.
If you have the GUI version just launch the application, select input and output. The commandline version takes input filename and optional output filename.
The commandline version has no dependencies and is easy to build, see Makefile.unix, or just make -f Makefile.unix. The GUI (primarily made for use in Windows) version can be built using CMake, note that FLTK is required (you can also build using FLTK directly fltk-config --compile geticc.cxx).
