I want to rotate 10 bit/component, 3 component RGB CGImages (or NSImages) by 90 degree angles. The images are loaded from 10 bpc heif files. This is for a Mac app, so I don't have access to UIKit.
My first thought is to use the Accelerate vImage framework. However, vImage does not seem to support 10 bpc images. In fact, I've tried this approach without success.
I know I can do this using the CIImage.oriented() method, but I don't want the substantial overhead of creating a CIImage from a CGImage and then rendering to a CGImage.
Any suggestions? Efficiency/speed are important. Thanks.
