- 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.
- Format used for saving large Photoshop documents over 30,000 by 30,000 pixels in size; supports images up to 300,000 by 300,000 pixels; to enable .psb support, check the "Enable Large Document Format" within the File Handling pane of the Photoshop Preferences window
