- Description
- The OTB (Nokia Over The Air Bitmap Image) file format is a type of image file developed for use on Nokia mobile devices. These files are specifically optimized for efficient transmission and display on Nokia phones, particularly older models. The OTB format is designed to be compact to facilitate over-the-air (OTA) transmission, which was an essential feature in the era of limited bandwidth and data transfer capabilities. The format supports monochrome graphics, making it suitable for simple images like icons and logos.
- Image saved in the native graphics format used by Silicon Graphics workstations; can store 8 to 32 bits per pixel; also supports Run-length encoding (RLE) compression for reducing the image file size.
