tb_lf_to_mla — 2D typed op

• 資料種類:lightfield → image

• 呼叫:fullseye.apply(img, "tb_lf_to_mla", a=0.5, b=0.5)(2-D 的模型是一張圖 + 兩個純量旋鈕 a,b∈[0,1])

用法

將光場重新交織為微透鏡陣列原始影格（精確逆變換）。

> 以下的詳細說明為原文 —— 摘要與標題已翻譯。

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`.

Typed bridge of the lightfield op `lf_to_mla into the 2-D evolution registry: the same implementation, called under the op(v, a, b) convention. This op has no tunable parameter; a and b` are unused.
