I have to apply a very slightly rotation to an image, a rotation of less than 1º. But it looks like all the rotation commands I've found can handle only integer angles: all the non-integer measures are truncated to a whole number. Therefore, it is impossible to get a <1º rotation.
I've tried to do the rotation with the
\rotatebox and the rotating package.
Of course, the problem is not to rotate one image but some hundreds of them. And 1º is quite relevant in a 20x20cm image inside a perfectly square frame.
