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.
The OTB (Over The Air Bitmap) file extension, developed by Nokia, is used for transmitting black and white bitmap images between mobile phones, particularly Nokia and Siemens models. These images, with a maximum resolution of 255x255 pixels, are often sent via SMS in either hexadecimal text or binary format. Historically, OTB files were popular in the early days of mobile communication for sending simple graphics, icons, and wallpapers when data transmission speeds were limited.
