vol_label_slice_rgb — VOLCOLOR `slice` op

• Data kinds: rgbvolume → rgbimage

• Call: import volcolor; volcolor.vol_label_slice_rgb(rgbvol, index: 'int', axis='z') (or opsvolcolor.get("vol_label_slice_rgb"))

Usage

Take one RGB cross-section out of a coloured volume (axial / coronal / sagittal).

*axis* は `"z"/"axial"/0((H, W, 3) が返る)、"y"/"coronal"`/1

(`(D, W, 3))、"x"/"sagittal"/2((D, H, 3)`)。**返る 2 軸が

軸ごとに違う**のは `(D, H, W) から 1 軸抜くのだから当然だが、(H, W)` を

期待して受けると縦横が入れ替わった絵が例外なしに出る。3 通りの形は

`tests/test_volcolor.py::test_slice_axes_shapes_and_content` が固定している。

*index* は非負でなければならない。`-1` を「最後の断面」として黙って

受けると、範囲外の指定が最後の断面として通ってしまう(切り出す位置が

1 箇所ずれた図は、機械にも目にも「壊れている」と見えない)。

Returns a contiguous float64 `(..., 3) copy. Raises ValueError` for a bad

volume, an unknown *axis*, or an out-of-range / negative *index*.
