How can I rotate an image about a specific pixel in Python? I am trying to de-rotate a set of images of the night sky. Since the stars rotate around Polaris, I could define Polaris as the center of rotation and rotate each image to line up the stars.
In phadej’s answer the transformation between the old and new coordinates of a point on the image is an affine transformation.
PIL (Python Imaging Library) has an image method called
transformwhich can perform an affine transformation of an image.The documentation for
transformis near the bottom of this page.
