lf_to_mla — LIGHTFIELD `decode` op

• Data kinds: lightfield → image2d

• Call: import lightfield; lightfield.lf_to_mla(lf) (or opslightfield.get("lf_to_mla"))

Usage

Re-interleave a light field into a microlens-array raw frame (exact inverse).

Inverse of :func:lf_from_mla with `offset=(0, 0)`: the returned frame has

shape `(H*V, W*U) and puts L[v, u, t, s]` back at raw pixel

`(t*V + v, s*U + u). lf_from_mla(lf_to_mla(L), (V, U)) returns L`

bit-for-bit (verified with `np.array_equal`), which is the cheapest

possible check that the decode's index arithmetic has no off-by-one.

Raises `ValueError`: *lf* not 4-D / non-finite / over the shape and

element caps (see :func:lf_from_mla), and a raw frame whose side would

exceed `MAX_SPATIAL * MAX_ANGULAR`.
