Hey anyone got a code snippet to rotate a UIImage in kotlin-wrapped iOS code? The compose imageviewer sample doesn't have this case covered, and trying to translate the common code online doesn't work. For example, this doesn't work:

let rotationTransform = CGAffineTransform(rotationAngle: rotationAngle)

In Kotlin, I can do:

val rotMat = CGAffineTransformMake(0.0, 1.0, -1.0, 0.0, 0.0, 0.0)

but now I need a way to apply it to my UIImage

@Dima Avdeev I see you wrote a lot of the code to do the image manipulation in imageviewer; do you have any tips? I'm just trying to do a simple image rotation

[Dima Avdeev]

Sorry, I wrote it in past. And actually forgot some of this code.
I think you can copy/paste it as is and try to shrink some redundant features.
