The GBR file format is associated with GIMP (GNU Image Manipulation Program), a freely distributed image editing software. It is specifically used to store custom brush designs that can be used within the GIMP software for various drawing and painting purposes. These brush files allow users to create and save their own brush patterns, shapes, and textures, enhancing their digital artwork and editing capabilities. The GBR format enables easy sharing and distribution of custom brushes within the GIMP user community.
The PI3 file type is associated with Degas & Degas Elite, which are image editing and drawing applications specifically designed for the Atari ST series of computers. These files contain images created or edited within the Degas or Degas Elite programs, capturing graphics in a format that supports the unique capabilities and limitations of the Atari ST's display. The PI3 format is particularly tailored for high-resolution monochrome images, reflecting the hardware's graphical output options at the time. While now considered a legacy format, PI3 files represent an important part of digital art history, especially within the context of early personal computing.
