rotate_image — 2D `geometry` op

• Data kinds: image → image

• Call: fullseye.apply(img, "rotate_image", a=0.5, b=0.5) (the 2-D model is one image plus two scalar knobs a,b∈[0,1])

• HALCON equivalent: rotate_image (the HALCON reference is a useful guide to its meaning and parameters)

Usage

> This operator's description has not been translated yet. The original text follows as it is.

画像を中心を軸に `-45°〜+45°(a` で決まる)回転する

(`scipy.ndimage.rotate、reshape=False` でキャンバスサイズを維持)。

枠外にはみ出す部分は反射(`mode="reflect"`)で埋めるため、四隅には元画像が

折り返して写り込む(帳票の傾き補正のように「枠外を背景色で埋めたい」用途

にはそのままでは向かない、既知の設計上の制約)。HALCON の

`rotate_image`（Rotate an image about its center.）に相当。

`a が回転角を -45°〜+45° の範囲で振る。b` は未使用。
