Color Equalizer - hue curve slider

I have a couple of questions about this slider:

  • What is the reason for the “Hue curve” slider not being available in the Saturation and Brightness tabs? It seems like it would be a nice addition to restrict the hue affected.

  • If you choose to show all the colour sliders and move the Options to a 4th tab, the Hue Curve slider is then nowhere to be found. Is this by design because it can’t be used with the Saturation and Brightness controls? It seems less than optimal to hide a useful slider in a specific view.

@hannoschwalm , I believe you worked on this module. Do you have any insight to the questions I had? Many thanks!

Yes by design as the resulting curve might be unstable leading to lots of artifacts and i simply didn’t want to discuss bad results from bad settings :slight_smile:

Ok, thanks for your answer! It’s a shame that the slider is hidden in the “alternative” view, but I understand your reasons.
