# Calculate Saturation

This plugin calculates the saturation from a picture with four different saturation algorithms:

  1. (max-min)
  2. (max-min) / sum
  3. like HSV: (max-min) / max
  4. like HSL: (max-min) / (max+min)

Build and install it with:

gimptool-2.0 --install elsamuko-saturation.c

Example:
