What I need is the full extent of both images, placed on the same pixel coordinate system. The problem is that, when the images are not fuly overlapping, the resultant image is cropped to only the common footprint of the two images.
I am already able to calculate the Affine Transformation rotation and offset matrix, which I feed to _transform to recover the dst-aligned src image. I have source ( src) image(s) I wish to align to a destination ( dst) image using an Affine Transformation whilst retaining the full extent of both images during alignment (even the non-overlapping areas).
