Why would it change? The content of the layer is what it displays, the rotation is part of the overall transform which is how it displays. The latter won't influence the former. Think of it like a photo on your desk. (A real physical paper one, mind.) Now turn it sideways. Did the photo change in any way? No, just how you see it. Now hold a magnifying glass in front. Still no change. CALayer is the same. You can move it around and turn it and blow it up and do various other transformations to it but this all simply modifies how it is displayed. Its content remains unchanged. > So, having different images facing different coordinates is the real fix to > this issue,? Im starting to believe that it is. Not knowing what the issue is, I couldn't say what the fix is. You don't describe why the above behavior is actually a problem for you, and I have a hard time seeing why it would be. If you want the images to point in different directions then just rotate the layer. Who cares if the image itself isn't changed?
