- 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.
- Group 4 (G4) used for black and white lossless compression to maintain high-quality images, commonly used in TIFF format compression by fax machines. A picture is seen as black dots and lines on a blank page; the fewer the dots and lines are, the lesser the file size.
