Convert rle to otb

What is the difference between .rle and .otb?

Description: The RLE (Run Length Encoded Bitmap) file type is a bitmap image format that employs run-length encoding, a simple compression technique to minimize file size without losing image quality. This method works by compressing sequences of identical pixels (runs) into a single value and count, rather than storing each pixel individually. RLE is particularly effective for images with large areas of uniform color, such as icons, line drawings, and simple graphics. It can significantly reduce file sizes, making it beneficial for storage.; 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.
