- Description
- An ICO file is an image format used to store icons for Windows programs, files, and folders. It contains two bitmaps: 1) the AND bitmap - the image mask (which determines what part of the icon is transparent) and 2) the XOR bitmap - contains the icon which is mapped onto the image mask. ICO files can be modified to create custom icons.
- 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.
