Created attachment 146704 [details] Original gradient with default gamma SUMMARY Gamma applied incorrectly. STEPS TO REPRODUCE 1. Create a gradient (sets gamma by default to 1/2.2): `convert -size 1280x720 -define gradient:vector=32,32,1248,688 gradient:#ff0000-#00ffff gradient.png` 2. Open image `gradient.png` in gwenview OBSERVED RESULT Colors are way too bright. EXPECTED RESULT Colors are correct. SOFTWARE/OS VERSIONS Linux/KDE Plasma: Kubuntu 21.04 KDE Plasma Version: 5.22.5 KDE Frameworks Version: 5.86.0 Qt Version: 5.15.2 ADDITIONAL INFORMATION When inverting the gamma value the image is displayed correctly, but metadata is actually wrong and other programs will make the image look wrong: `convert gradient.png -set gamma 2.2 gradient-inverted-gamma.png`
Just upgraded the system to check if anything has changed, but no. gwenview version: 21.12.2 SOFTWARE/OS VERSIONS Linux/KDE Plasma: Kubuntu 21.10 KDE Plasma Version: 5.24.0 KDE Frameworks Version: 5.91.0 Qt Version: 5.15.2
