Thanks Xavier. That was it. I had tried 45f as the value earlier but
replaced it with a value from one of the examples.

Much appreciated.

Damian.

-- --BEGIN PGP SIGNED MESSAGE-- -- Hash: SHA1 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. Xavier
