Inverse image transform
Does Sage have an inverse image transform?
By that, I mean is there a function where, given an image X, and function f, it generates an image Y, such that pixel p of Y is assigned the color of f(p)∈X?
Note that for convenience, you can also say what rectangle the input and output image represent. (I.e. you could say that pixels in Y correspond to points in [−1,1]×[−1,1].
For reference, here is mathematica's version is called ImageTransformation
