    Is there a 'doit' routine for rotating images by a specific angle? I know the capability exists through the 'Rotate/Flip Data' tool. (Basic Tools -> Rotate/Flip Data). This tool allows the user to input an angle that the image should be rotated. However, the 'ROTATE_DOIT' routine does not take an angle as an input. It looks like the only options for rotation here is to use the ROT_TYPE keyword which only allows for rotations that are multiples of 90 degrees, not any other angles. Is there another 'doit' that allows for this?

    I'm afraid that there is not another DOIT routine that allows users to specify any rotation angle. I also checked the newer ENVI API. DOIT routines are part of the ENVI Classic API and there is a newer API that uses the concept of ENVI Tasks instead of DOIT routines. But I don't see a routine in that API that allows for image rotation. - Peg Exelis VIS
