linear color space blending
keszegh
Member
so in my drawing app i encounter regularly the issue that arises from sprites not blending in a linear color space but in a 'usual (visually wrong) way'. see this article here for examples (e.g. antialiasing making dark edges of brush strokes) and an explanation:
https://ninedegreesbelow.com/photography/test-for-linear-processing.html
perhaps i could add shaders that handle this situation but i don't really know how and anyway it would be much more effective if there would be a global way to do it. moreover perhaps QT allows this and so there is no need to reinvent the wheel.
so overall my request is to add a way to make my app blend sprites using a linear gamma color space. or if this seems complicated then let's discuss here how one can do it.
thanks

But I have never used it.
Your Qt link seems indeed legit
