HCG support

Open ghost opened this issue 9 years ago • 0 comments

Hello. Can you implement HCG? I can help by tips.

  • Chroma (C value) is second channel of HCG (i.e. chroma, C_hcg), without any operation.
  • m (min of RGB) value can be calculated by G_hcg * (1 - C).
  • G_hcg can be calculated by m / (1 - C) if you convert from RGB
