rounded_rect — ANNOTATE `shape` op

• Data kinds: image2d → image2d

• Call: import fullseye as fs; fs.ledger.rounded_rect(img, rect, radius=8, color='neutral', width=2, fill=False, alpha=1.0, scheme='okabe_ito') (to call the implementation directly, import annotate; annotate.rounded_rect(img, rect, radius=8, color='neutral', width=2, fill=False, alpha=1.0, scheme='okabe_ito'); from the registry, opsannotate.get("rounded_rect"))

Usage

A rounded rectangle (filled with `fill=True`). For backing plates and enclosing boxes.

Raises

------

ValueError

矩形が画像の外、radius が負か辺の半分を超える、alpha が [0,1] の外。

描画: 画素中心から「角を丸めた矩形」までの距離で内側判定し、`fill=False`

なら外周から `max(1, width)` px 幅の帯だけを載せる(距離判定の 1 段階、

アンチエイリアスは無し)。合成は `out = m*color + (1-m)*img に alpha` を

掛けたもの。

• `img: (H, W) / (H, W, 1|3|4)。float64 に変換し [0, 1]` にクリップした

複製を返す(入力は変えない)。NaN/Inf は `ValueError`。

• `rect: (x, y, w, h)、x = 列・y = 行。丸めて整数化し、w, h > 0`、

画像内に完全に収まること(はみ出しは切り詰めず `ValueError`)。

占める画素は `x .. x+w-1、y .. y+h-1`。

• `radius: 角の半径 [px]、0 <= radius <= min(w, h)/2`。0 で普通の矩形。

• `color: palette の役割名("neutral" 等、scheme` で解決)か

`[0, 1]` の RGB。グレー画像には RGB の平均を使う。

• 返り値: 入力と同形の float64。

`text_box の下敷きや annotate_legend` の囲みと同じ見た目を手で組むときに。
