Per Wikipedia: DPaint began as an in-house art development tool called Prism. As author Dan Silva added features to Prism, it was developed as a showcase product to coincide with the Amiga's debut in 1985. Upon release, it was quickly embraced by the Amiga community and became the de facto graphics (and later animation) editor for the platform. It was used almost ubiquitously in the making of Amiga games, animation and demoscene productions. Amiga manufacturer Commodore International later commissioned EA to create version 4.5 AGA to bundle with the new Advanced Graphics Architecture chipset (A1200, A4000) capable Amigas. Version 5 was the last release after Commodore's bankruptcy in 1994.

With the development of Deluxe Paint, EA introduced the ILBM and ANIM file format standards for graphics. While widely used on the Amiga, these formats never gained widespread end user acceptance on other platforms, but were heavily used by game development companies. Dpaint was used by Lucasarts to make graphics for their adventure games such as Monkey Island, and is the source of the name of the main character in the Monkey Island series, Guybrush Threepwood[1] - the character's name derived from a particular filename used to store his image data, which was named "guybrush.bbm".[2]
