I think the problem is that you're not using degrees to specify the
rotation.
You should replace:
img.setRotationDegrees((float)Math.PI / 4); //rotate 45 degrees
with:
img.setRotation((float)Math.PI / 4); //rotate 45 degrees
or use 45 in the call to setRotationDegrees() as your existing code will
rotate the text less than one degree.
