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 PC1 file type is associated with Degas & Degas Elite, which are graphics programs designed for use on the Atari ST series of computers in the 1980s. These applications were popular for their ability to create detailed digital art and illustrations, leveraging the advanced graphical capabilities of the Atari ST. PC1 files specifically contain image data saved in a format native to these programs, supporting various resolutions and color palettes available on the Atari platform. Due to the specialized nature of the PC1 format, opening or editing these files requires specific software or emulators capable of emulating the Atari ST environment.
