The JBG file extension stands for Joint Bi-level Image Group, a format developed for efficient lossless compression of binary images, primarily used in fax transmissions. Introduced by the Joint Bi-level Image Experts Group, JBG files store 1-bit raster images and offer superior compression compared to older standards like CCITT Group 3 and 4. Although initially popular for fax machines, the format has largely been superseded by JBIG2, which provides even better compression.
The RGF (LEGO Mindstorms EV3 Robot Graphics File) is a proprietary raster image format used by the LEGO Mindstorms EV3 software to create and edit images for programming LEGO robots. These files, which include text boxes, shapes, and drawings, are designed to be displayed on the EV3 robot's screen or within the programming environment. The format was developed by LEGO to facilitate the integration of visual elements into robot design and programming tasks.
