Please refer to this example below:

The goal is rotate the image multiple times to create individual movie frames for an animation effect. The area within the rectangular marquee represents the portion of the image to be cropped for the frames.
Rotating the canvas causes the marquee to disappear. Additionally, “eyeballing” the area to be cropped after successive rotations is not desirable, as all frames need to be exactly the same size, and need to be geometrically consistent.
I know how to rotate the image, but how can I crop out the frames via keeping the marquee “locked” in position?
Any information would be greatly appreciated.
