Is there a way to compose two of these to plot the Riemann map between two different arbitrary domains?

https://ask.sagemath.org/question/44684/riemann-map-between-two-different-domains/?answer=44687#post-id-44687If you have two RiemannMap objects A and B, then at least you have easy access to the point-wise map via composing one with the inverse of the other:
BtoA = lambda(z): B.riemann_map(A.inverse_riemann_map(z))
be careful, though: the computation of these maps only seem to have a few digits of precision, so you'll quickly see numerical artifacts.Mon, 17 Dec 2018 02:16:19 +0100https://ask.sagemath.org/question/44684/riemann-map-between-two-different-domains/?answer=44687#post-id-44687
