Hello, I currently treat images ASAR and I would have to like to know how I could make to turn them of a some angle (36° example). The problem which I meeting is as follows, there is a function well ' rotate_doit' which makes it possible to turn the image but with preset angles and the function ' rotate' of IDL does not function (IDL don't can open an image ASAR). If somebody can help me that too will not be. Thank you in advance.
