The CAL file extension, known as CALS (Continuous Acquisition and Life-cycle Support) Type 1 Image, is a 1-bit black-and-white raster image format developed by the U.S. Department of Defense in the mid-1980s to standardize graphics data interchange for military documentation. It is primarily used for storing and sharing monochrome images while retaining orientation metadata. The format supports both uncompressed and compressed (using CCITT Group 4 compression) images.
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.
