Save the JPEG as 4:4:4 chroma?

Hey guys. Is there any way to save the JPEG with 4:4:4 chroma for better quality in iOS interface? Or just a third party library?


Thank you.

If you mean how to control chroma subsampling/decimation, coreimage framework docs has an article on applying a chroma key effect that might lead to something you can use?
