vol_label_mpr_rgb — VOLCOLOR slice op

Data kinds: rgbvolumergbimage

Call: import volcolor; volcolor.vol_label_mpr_rgb(rgbvol, center=None, gap: 'int' = 4, background=(0.05, 0.05, 0.07)) (or opsvolcolor.get("vol_label_mpr_rgb"))

Usage

The three orthogonal cuts of a coloured volume, laid out as one RGB image.

> The detailed description below is the original text — the summary and the headings are translated.

左から axial `(H, W) / coronal (D, W) / sagittal (D, H)`。*center* は

`(z, y, x)` の交点(既定は各軸の中央)。パネルの高さは最大値へ *background*

で下詰めパディングし、間に *gap* 画素の隙間を空ける。

ラベル色がボリューム由来であることがこの図の意味である ―― 3 面で同じ部品が

同じ色に見えることが、3 断面が同じラベリングから来ている証拠になる

(断面ごとに色を付け直した図では 3 面の色は一致しない)。

Returns float64 `(H_out, W_out, 3). Raises ValueError` for a bad volume,

a *center* outside the volume, or a negative *gap*.
