How to rotate an external image in sage
I want to rotate an external image in sage. I know how to rotate a plot created on sage and how to load an external image and view it later, but i cant use de function rotate on an external image. When I try to rotate the image with "rotate" sage says that the object doesnt have such attribute. Does someone know how to do it?
Can you include code for what you know how to do and for what you have tried?
