Limitations
Some features that have been often asked for, but aren't currently
implemented are:
- ICC Version 4 profile support
- Monochrome profiling support
- More than 4 colorant printer support
- GUI interface
- Support for all available instruments
Some of these features are being worked upon, and some are beyond the
scope of a non-commercial project. The range of instruments supported
is mainly limited by the availability of information on their
interfaces, as well as the instruments themselves.
The file ttbd.txt in the source distribution has a longer and more
detailed list of feature ideas.
