Hi, It happens that one spends some time to draw a sensor curve and then wants to quickly compare the result with another curve. I think it would be of help if there were 2 copy/paste buttons right next to the sensor curve graph: they would simply copy or paste a copied curve into the graph. - Original forum thread: https://forum.kde.org/viewtopic.php?f=288&t=156122&p=407830#p407830 - Image showing how Rawtherapee has implemented them: http://rawpedia.rawtherapee.com/Exposure#Tone_Curves. Thanks!
Note: the same curve file format (and saving/loading code) should be used for all three suggested options: - curve adjustments (bug 387352) - global pressure curve - brush editor sensor curves (bug 391927, related: bug 401496 (this one))
