PICT is a graphics file format introduced on the original Apple Macintosh computer as its standard metafile format. It allows the interchange of graphics, and some limited text support, between Mac applications, and was the native graphics format of QuickDraw. The original version, PICT 1, was designed to be as compact as possible while describing vector graphics. To this end, it featured single byte opcodes, many of which embodied operations such as "do the previous operation again".

  • PICT is a graphics file format introduced on the original Apple Macintosh computer as its standard metafile format. It allows the interchange of graphics, and some limited text support, between Mac applications, and was the native graphics format of QuickDraw. The original version, PICT 1, was designed to be as compact as possible while describing vector graphics. To this end, it featured single byte opcodes, many of which embodied operations such as "do the previous operation again". As such it was quite memory efficient, but not very expandable. With the introduction of the Macintosh II and Color QuickDraw, PICT was revised to version 2. This version featured 16-bit opcodes and numerous changes which enhanced its utility. PICT 1 opcodes were supported as a subset for backward compatibility. Within a Mac application, any sequence of drawing operations could be simply recorded/encoded to the PICT format by opening a "Picture", then closing it after issuing the required commands. By saving the resulting byte stream as a resource, a PICT resource resulted, which could be loaded and played back at any time. The same stream could be saved to a data file on disk (with 512 bytes of unused header space added) as a PICT file. With the change to Mac OS X, PICT was dropped in favour of Portable Document Format (PDF) as the native metafile format, though PICT support is retained by many applications as it is so widely supported on the Mac.
  • PICT (als Dateiendung wird auch pct benutzt) ist ein vorwiegend internes Grafikformat (metafile) der Apple-Betriebssysteme bis Mac OS 9. Es gehört zur Bildschirmbeschreibungssprache QuickDraw. Es kann Pixel-, Vektor- und Textinformation enthalten. Unter Mac OS X wurde es von PDF abgelöst. Es entspricht Windows Metafile (WMF bzw. EMF) unter Windows.
  • PICT est un format de fichier graphique créé par Apple comme métafichier standard pour ses premiers Macintosh. Il peut contenir des informations graphiques bitmap ou vectorielles, ainsi que quelques champs de texte. C'est également le format natif de QuickDraw Manager. La première version, PICT 1, a été conçue comme la plus compacte possible pour la description vectorielle, notamment par l'insertion de commande de type "refaire l'opération précédente". Avec le Macintosh II et Colour Quickdraw, PICT passa en version 2, désormais 16 bits, la compatibilité descendante étant assurée. Lors de l'utilisation d'une application Macintosh, toute image peut être convertie en PICT par simple copier/coller, vers une image de destination. Un exemple concret est la personnalisation des icônes du Finder. Avec le passage à MacOS X, le PICT a été remplacé par le pdf en temps que métaformat natif. Cependant la compatibilité avec le PICT est encore largement assurée.
  • Il Macintosh Picture, o brevemente PICT, è un formato di file grafici introdotto nel primo computer Apple Macintosh come formato standard metafile. Esso consente lo scambio di grafica (sia bitmap e vettoriale), e di qualche formato di testo limitato, tra le applicazioni Mac, ed è stato il formato grafico nativo di QuickDraw. La versione originale, PICT 1, è stata progettata per essere il più compatta possibile, nel descrivere la grafica vettoriale. A tal fine, è caratterizzata da un singolo byte di operation codes(opcodes), molte delle quali incorporavano operazioni come "ripeti la precedente azione". Nel progetto di origine, caratteristica portante era la memoria, anche se non molto espandibile. Con l'introduzione del Macintosh II e del Color QuickDraw, PICT è stato revisionato e aggiornato alla versione 2. Questa versione era caratterizzata da opcode a 16 bit e numerosi cambiamenti che rafforzavano la sua utilità. Gli opcode del PICT1 sono stati rivisti come un sottopacchetto per favorire la retrocompatibilità. In ogni applicazione Mac, qualsiasi sequenza di operazioni di disegno può essere semplicemente registrata o codificata nel formato PICT, tramite l'apertura di una "immagine",e la successiva chiusura dopo aver rilasciato i comandi richiesti. Dal salvataggio del derivante flusso di byte come una risorsa, una risorsa PICT, tutto ciò può essere caricato e riprodotto in qualsiasi momento. Lo stesso flusso può essere salvato in un file dati su disco (con 512 byte di spazio inutilizzato aggiuntivi) come un file PICT. Con il cambiamento di Mac OS X, il formato PICT è stato abbandonato a favore del Portable Document Format come formato nativo metafile, sebbene il supporto PICT è supportato da molte applicazioni, così com’è ampiamente supportato su un computer Mac.
  • QuickDraw Picture(PICT(ピクト))は、Appleによる画像描画ルーチン「QuickDraw」の標準的な画像ファイルフォーマット。ラスターイメージの他に、動画やベクターイメージを表現したりすることも可能である。 その内部はQuickDrawが解読していく命令と実際の画像からなる。基本的に、ベクターイメージや画像の付加情報は命令で構成され、ラスターイメージは各ピクセルの情報がそのまま保存されている。また、ビットマップ(ラスターイメージ)は連長圧縮(PackBits)法で、QuickTimeがあればJPEGやPNGなどにより圧縮されることもある。QuickDrawへの命令を含むため、PICTはメタファイルの一種でもある。 Appleの定めにより、画像を扱うほとんどすべてのアプリケーションはこのファイルフォーマットをサポートしている。また、フォーマットは公開されているため、MacでPICTを扱えるようにするのは容易である。ただし、当然のことながら、QuickDrawの描画命令を埋め込んだ形式は、QuickDrawがなければ扱えるようにすることは難しい。ただ、QuickDrawの描画命令も公開されているので、ビットマップ(ラスターイメージ)を開くだけなら簡単なはずである。しかしながら、PICTに関するドキュメントは少なく、Windowsでは対応していないアプリケーションがほとんど。優秀なアプリケーションならQuickTimeにデータを送って描画してもらい、その結果を受け取って表示してくれるものはある。すなわち、QuickDrawがなくてもQuickTimeで表示することは可能である。
