Detailed Description
gamma correction
Input is a gamma correction value in the range ]0.0 .. 10.0]; the color values get corrected using
col(r,g,b) = clamp(pow(col(r,g,b), 1.0 / gamma), 0.0, 1.0) Red, Green, Blue, Luminance and Contrast correction
Input are percent values from [-1.0 .. 1-0] which correspond to -100% to 100% correction of Red, Green, Blue, Luminance or Contrast. 0.0 means no change of the corresponding channel. All these are combined (but can be used single) to
- be able to cover a bigger change range utilizing the combination
- allow execution by a small, common, precalculated table mix a part of the original color with randomized color (mainly for debug visualizations)
