In [[computing]], a '''bitmap''' (also called '''raster''') graphic is an image formed from rows of different colored [[pixel]]s.<ref>{{cite web |dateurl=September 22, 2023 https://kb.iu.edu/d/afmr|title=ARCHIVED: What are bitmap and vector graphics, and how are they different |urlpublisher=https://kb.iu.edu/d/afmrUniversity Information Technology Servivces|language=en-US|url-status=live |archive-urldate=https://alightmotionproapks.comSeptember 22, 2023|archiveaccess-date=April 21, 2024 |accessarchive-date=April 21, 2024 |publisher=University Information Technology Servivces |language=enarchive-USurl=https://archive.today/20240421071909/https://kb.iu.edu/d/afmr}}</ref> A [[GIF]] is an example of a graphics image file that uses a bitmap.<ref>{{cite encyclopedia|url=https://www.britannica.com/technology/bitmap|title=bitmap|encyclopedia=[[Encyclopædia Britannica]]|author=Gregersen, Erik|language=en-GB|url-status=live|date=January 26, 2022|access-date=April 21, 2024|archive-date=April 21, 2024 |archive-url=https://archive.today/20240421072042/https://www.britannica.com/technology/bitmap}}</ref>

As a noun, the term "bitmap" is very often used to refer to a particular bitmapping application: the '''pix-map''', which refers to a map of [[pixel]]s, where each pixel may store more than two colors, thus using more than one bit per pixel. In such a case, the ___domain in question is the array of pixels which constitute a digital graphic output device (a screen or monitor). In some contexts, the term ''bitmap'' implies one bit per pixel, whereas ''pixmap'' is used for images with multiple bits per pixel.<ref>{{cite book |author=James D.
