You can set the value of the property 'contentsGravity' to
kCAGravityResizeAspect.

Hi,
I provide a CGImageRef as the layer content. When the bounds of layer
is changed, the image seems to be scaled to fit the bounds.
Is there an option to keep the image aspect ratio? what possible
key-value can I set for the layer's style property?
Thanks,
