What is the difference between .otb and .dib?

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.; Generic Windows or OS/2 bitmap graphic; similar to a .BMP file, but has different header information; supports 1, 4, 8, and 24 bits per pixel if the image is uncompressed and 4 and 8 bits per pixel if the image uses RLE compression; a 24-bit DIB image contains 8 bits, or 1 byte for each RGB color.
