ccss2edr

This tool converts Argyll .ccss (Colorimeter Calibration Spectral Set) files to the X-Rite .edr format.

The motivation is to get more accurate color calibration using the i1Display Pro (i1d3) colorimeter in software that uses the X-Rite SDK, like Calman or X-Rite i1Profiler. The SDK ships with some generic EDRs that may not accurately match the spectral distribution of your display. Converting a .ccss correction file for your specific device (for example, from the DisplayCAL corrections database) and replacing the generic EDR should yield better results.
