複数のアンカーポイントのハンドルをリセットする方法

Question

選択した複数のアンカーポイントのハンドルをすべてリセットする方法を探しています。

図形画像を選択範囲からパス化をして図形のシェイプをつくった時、

アンカーポイントのハンドルが変な状態で入っていたりして選択元の図形画像の

形に添っていないときがあります。

ですので、すべてのアンカーポイントを「アンカーポイント切り替えツール」で

選択してハンドルのリセットをして形状を整えているのですが、アンカーポイントが多いととても手間です。

複数のアンカーポイントのハンドルをリセットする方法はありますか？

PhotoshopのJavaScriptは一般的なWebのそれとはかなり毛色の違うものであり、ECMA 3相当の骨董品でもあります。

DOMもかなり違いますから、まずはリファレンスに目を通しましょう。Photoshop JavaScript referenceはありますが、スキルレベルによっては適当な情報をググった方が早いかもしれません。

パスポイントの操作は

app.activeDocument.pathItems[0].pathPoints

の各アンカーポイントのleftDirection及びrightDirectionに対してanchorをループにて適用する処理になります。
