Amyspark's YCbCr ICC profiles

This project enables the creation of ITU-R BT.601-7 and BT.709-6 ICC profiles.

Characteristics

• Full-range, floating point Y, Cb, and Cr channels
• Supports both the BT.601/709 OETF as well as the BT.1886 EOTF curve
• v2 and v4 profiles
• For the v4 profiles, a DtoB0 tag is included that packs the complete pipeline in floating point precision (see caveat below)

Limitations

• The v2 profiles pack the complete transformation into a single CLUT, due to tag limitations
• The v4 profiles pack the YCbCr <-> RGB step into a CLUT for the same reason; the remaining steps are explicitly saved into the AtoB0 components
• The BT.601/709 curve must be sampled prior to storage in DtoB0 because its parametric shape is not supported by the tag
