オープンソースの「RectangleBinPack」を用いて2D Bin Packagingを解き、Keynote上の汎用オブジェクト(iWork item)を指定矩形内に詰め込むAppleScriptです。
2D Bin Packは、指定のオブジェクトを面積で評価して、ターゲットの領域に「詰め込む」(オブジェクト回転あり)という処理で、ワードクラウドであるとか、記事レイアウト時の最適化配置といった用途に用いられます。
さまざまなアルゴリズムが提唱され、コンピュータの登場初期からどえらい先人たちが攻めまくった分野であるため、ありがたく、その成果をいただいているという用途でもあります。
よく、ゲームのテクスチャ画像を1枚の画像ファイルに詰め込む際に2D Bin Packの処理を用いている例を見かけます。なんでファイルごとに分けないのかはわかりませんけれども(ファイル容量の節約???)。

オープン中のKeynote書類の表示中のスライド(ページ)上にある矩形オブジェクト(Shape)を指定の矩形エリア内に2D Packingします。エリアの大きさが小さすぎると正常にPackingされなかったり、false(エラー)を返したりします。
変更履歴:
v2.1: BinPackTestをIntel x64とARM binaryのそれぞれのバイナリでビルドしてバンドルに入れた(Makeを書き換えて直接Universalバイナリに仕立てられるといいのに)
v2.2: BridgePlusがなくても動くように書き換えた(ないと動かないのはいろいろ運用上問題がある)
v2.3: shapeに対してBinPackしていたのを、Keynote上の汎用オブジェクトへのアクセス予約語iWork itemでアクセスするように変更した
