RGBtoXYZ()

QMatrix4x4 MythColourSpace::RGBtoXYZ ( const MythColourSpace &  Primaries )

static

Create a conversion matrix for RGB to XYZ with the given primaries.

This is a joyous mindbender. There are various explanations on the interweb but this is based on the Kodi implementation - with due credit to Team Kodi.

Invert the result for the XYZ->RGB conversion matrix.

Note

We use QMatrix4x4 because QMatrix3x3 has no inverted method.
