Add chroma subsampling option #266

Closed Doofy420 closed 2 months ago

Doofy420 commented 3 months ago

I'm trying to optimize a lof of images without losing too much quality and the ability to pick or disable chroma subsampling would be really useful. It seems that checking the lossless option is the only way to disable it atm.

In the core library there's an option to set Chroma Subsampling, it's just not exposed in the UI. With release 2.7.0 I'm adding a few "advanced" options for some formats, I might add this one too.
