QuickDraw is the 2D graphics library and associated Application Programming Interface (API) which is a core part of the classic Mac OS operating system. It was initially written by Bill Atkinson and Andy Hertzfeld. QuickDraw still existed as part of the libraries of Mac OS X, but had been largely superseded by the more modern Quartz graphics system. In Mac OS X v10.4, QuickDraw has been officially deprecated. In Mac OS X v10.5 applications using QuickDraw cannot make use of the added 64-bit support. In Mac OS X v10.8, QuickDraw support was removed from the operating system. Applications using QuickDraw will still run under OS X 10.8; however, the current versions of Xcode and the macOS SDK do not contain the header files to compile such programs.

  • QuickDraw è il motore grafico bidimensionale del sistema operativo Mac OS prodotto da Apple. È stato progettato e realizzato da Andy Hertzfeld e Bill Atkinson. Con l'arrivo del macOS Apple sviluppò un nuovo motore grafico chiamato Quartz. QuickDraw è incluso in Mac OS X per poter mantenere la compatibilità con le applicazioni precedenti, l'emulatore Classic necessità del supporto di QuickDraw per funzionare.
  • QuickDraw (kurz: QD) war die 2D-Bildschirmbeschreibungssprache des Macintosh bis Mac OS 9.2.2 und ein Bestandteil des Macintosh-Baukastens. In Mac OS X wurde sie von Quartz abgelöst, ist jedoch als Bestandteil der Carbon-Programmierschnittstelle noch verfügbar. Der theoretische Ursprung scheint in der Doktorarbeit von Bill Atkinsons Professor Jef Raskin zu liegen: A Hardware-Independent Computer Drawing System Using List-Structured Modeling: The Quick-Draw Graphics System, Pennsylvania State University, 1967.
  • OS Xでは後継のQuartz 2Dを利用することが推奨されているが、従来との互換のためQuickDrawも残されている。 QuickDrawの最初のバージョンはビル・アトキンソンほぼ一人により書かれた。元々は Lisa用の描画関数群としてLisaGrafという名前で開発されていたが、Macintosh にも搭載されることが決まりQuickDrawと改称された。 1979年にアップル社員が XEROXの研究所PARCを見学した際、 Altoで動くSmalltalkシステムを見せられた。当時のSmalltalk GUIでのウインドウは単純な矩形の組み合わせで描画され、また、他のウインドウに隠れて一部分しか見えていないウインドウの表示内容の更新もおこなわれていなかった。しかし、Altoのハードウェア機能(描画に必要なビット転送ルーチンであるBitBLTのマイクロコード化など)を介した比較的高速な描画を見て、不定形クリッピング描画が実現されていると誤った思い込みをしてしまったビル・アトキンソンは、その認識のまま遂に“リージョン”の描画や演算処理を比較的高速に扱えるLisaGrafやQuickDrawを完成させてしまった。後に、 QuickDrawの功績により彼はアップル・フェローの地位を与えられた。
