はそれを手に入れました! (このコードは10.7しか働いていません)最終画像がサムネイル画像にレンダリングされる前にアイコンが描画されていたので問題が発生していました。オーバーレイはいつもそこにあった...それは私が間違っていた描画操作の順序だった...!

このコードの影響を確認しましたか?その本当に興味深い...画像を置き換えるように思えるのは、ファインダーが他のオーバーレイをアイコンに書き込むときに奇妙な問題を引き起こすようです...デスクトップ上のアイコンの半分を元のアイコンを適切に描くことができますが、それらは – Orbitus007
どのようにマーベリックスでこれを行うには? – Ali
