I'm interested in placing a single pixel border around a rotated layer. I know I could do this by setting a border and borderWidth - but when the entire thing is scaled; these borders are also scaled (not ideal)

I can't think of any other way of doing it other than having another layer sitting on top of the rotated layer, being exactly the right size as the rotated layer and with the same rotation (thus it should appear to be the same size position etc). With a scale of 1, it'll draw it's border correctly.

Is there a more sensible way to do this in CoreAnim that anyone knows of?

Regards,
Neil Clayton
