QuickDraw

<p>QuickDraw was the 2D <a href="/facts/Computer_graphics/lapBE8wv">graphics</a> library and associated <a href="/facts/Application_programming_interface/GMlN4vUr">application programming interface</a> (API) which is a core part of <a href="/facts/Classic_Mac_OS/I5fQq44K">classic Mac OS</a>. It was initially written by <a href="/facts/Bill_Atkinson/AnN2LdVc">Bill Atkinson</a> and <a href="/facts/Andy_Hertzfeld/4pf6AFpK">Andy Hertzfeld</a>. QuickDraw still existed as part of the libraries of <a href="/facts/Mac_OS_X/Y93vVpTm">Mac OS X</a>, but had been largely superseded by the more modern <a href="/facts/Quartz_(graphics_layer)/FLvFwpYt">Quartz</a> graphics system. In <a href="/facts/Mac_OS_X_Tiger/q6vKCpvq">Mac OS X Tiger</a>, QuickDraw has been officially <a href="/facts/Deprecation/1aQL7rnP">deprecated</a>. In <a href="/facts/Mac_OS_X_Leopard/UmXw4H5x">Mac OS X Leopard</a> applications using QuickDraw cannot make use of the added 64-bit support. In <a href="/facts/OS_X_Mountain_Lion/GIu66667">OS X Mountain Lion</a>, QuickDraw header support was removed from the operating system. Applications using QuickDraw still ran under OS X Mountain Lion to macOS High Sierra; however, the current versions of Xcode and the macOS SDK do not contain the header files to compile such programs.
