'''MacPaint''' var et [[bitmap]]-basert tegneprogram utviklet av [[Apple Computer]] og lansert sammen med den opprinnelige [[Macintosh 128K|Macintosh-modellen]] [[24. januar]] [[1984]]. MacPaint var bemerkelsesverdig da det ble lansert fordi det kunne generere grafikk som kunne brukes av andre programmer. Ved å bruke maskinens [[datamus|mus]], utklippsboken og det innebygde grafikkspråket [[QuickDraw]] kunne tegninger klippes ut fra MacPaint og limes inn i dokumenter i tekstbehandlingsprogrammet [[MacWrite]].<ref name="nyt">.{{Kilde www

MacPaint ble utviklet av [[Bill Atkinson]], som var en av medlemmene i gruppa som utviklet Macintosh hos Apple.<ref name="revolution">{{Kilde bok

Den siste versjonen av MacPaint var versjon 2.0 som ble utgitt i 1988. MacPaint ble nedlagt av Claris i 1998 p.g.a. sviktende salg.<ref name="discontinued">{{cite news

=== Development ===
MacPaint was written by [[Bill Atkinson]], a member of Apple's original Macintosh development team.<ref name="time"/> The original MacPaint consisted of 5,804 lines of [[Pascal (programming language)|Pascal]] [[source code|computer code]], augmented by another 2,738 lines of [[Motorola 68000|68000]] [[assembly language]].<ref>Hertzfeld (2005), p. 174</ref> MacPaint's user interface was designed by [[Susan Kare]], also a member of the Macintosh team.<ref name="kare">{{cite news

MacPaint uses two offscreen [[data buffer|memory buffers]] to avoid flicker when dragging shapes or images across the screen.<ref name="buffer">Hertzfeld (2005), p. 171</ref> One of these buffers contained the existing pixels of a document, and the other contained the pixels of its previous state.<ref name="buffer"/> The second buffer was used as the basis of the software's [[undo]] feature.<ref name="buffer"/> In April 1983, the software's name was changed from MacSketch to MacPaint.<ref>Hertzfeld (2005), p. 172</ref> The original MacPaint was programmed as a single-document interface. The palette positions and sizes were unalterable, as was the document window. This was different from other Macintosh software at the time, which allowed the users to move windows and resize them.

The original MacPaint did not incorporate a zoom function. Instead of a zoom function, a special magnification mode called Fat Bits was used. Fat Bits showed each pixel as a clickable rectangle with a white border. The Fat Bits editing mode set the standard for many future editors.<ref>Hertzfeld (2005), p. 147</ref> MacPaint included a "Goodies" menu which included the Fat Bits tool. This menu was named the "Aids" menu in prerelease versions, but was renamed "Goodies" as public awareness of the [[AIDS]] epidemic grew in the summer of 1983.<ref>Hertzfeld (2005), pp. 155-156</ref> -->
