symmetric_peg_shape — DRIVE pegtactile op

• Data kinds: text → image2d

• Call: import fullseye as fs; fs.ledger.symmetric_peg_shape(name: 'str', size: 'int' = 160, radius: 'float' = 50.0, angle: 'float' = 0.0, centre=None, ss: 'int' = 8) -> 'np.ndarray' (to call the implementation directly, import pegtactile; pegtactile.symmetric_peg_shape(name: 'str', size: 'int' = 160, radius: 'float' = 50.0, angle: 'float' = 0.0, centre=None, ss: 'int' = 8) -> 'np.ndarray'; from the registry, opsdrive.get("symmetric_peg_shape"))

Usage

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

ペグの断面(真値つきの合成、反エイリアスの被覆率 0..1、(size, size)): 円・正三角形・正方形・正六角形(外接円半径 `radius`

[px])・キー付きの円(D カット: 円の一部を弦で切る、n = 1)。`angle` [rad] だけ形を回して描く(画像を回すと補間が入る)。

`centre = (col, row)、ss` = 画素あたりの副標本の 1 辺。Raises ValueError: 未知の形、size < 16、radius ≤ 0、ss < 1。
