libXcm

The libXcm library contains the a reference implementation of the X Color Management specification. The X Color Management specification allows to attach colour regions to X windows to communicate with colour servers.

The XcmDDC API can be used to fetch a EDID data block from a monitor over a i2c communication. On Linux typical the i2c-dev module must be loaded to use this hardware data channel. The device nodes must obtain rights accessible to normal users.

The XcmEdidParse API is for parsing EDID data blocks. A small example application is included.

The XcmEvents API allowes to easily observe X11 colour management events. The included xcmsevents makes use of the XcmEvents API.
