One known issue is that with orientations > 4, the transformed image will have different dimensions from its box so that whitespace might appear on the right and at the bottom of the image.
@JureSotosek you can do it with an additional container that will have the dimensions of your box with overflow hidden. i've done something similar just need to dig up the code, and add it to this package.

:Any known workaround for this?
