The LEGO Mindstorms EV3 Robot Graphics File (RGF) is a proprietary binary file format used by the LEGO Mindstorms EV3 software to store robot graphic models. It is a vector-based file format that stores information such as the robot's 3D geometry, color and other visual properties, as well as the model's connection points, used for connecting with other LEGO elements.
A PJPEG file is a bitmap image created in the Progressive JPEG format (PJPEG). It contains encoded bitmap data so that the downloaded image appears progressively from a blurry picture to the final sharp image. PJPEG files may also fill alternating horizontal lines until the full picture is revealed.
