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.
Created by Digital Equipment Corporation (DEC), SIXEL is a bitmap image format in an escaped sequence (seen as six pixels high and one pixel wide). You have to convert it into a more accessible format if you don’t have a DEC terminal to view it.
