- 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 TN3 file type, associated with the "Tiny" descriptor, is a compressed image file format designed for efficient storage and quick loading of graphics. It is often utilized in applications or environments where memory and storage space are limited, such as older or embedded systems. TN3 files achieve their compact size through compression algorithms that reduce file size without significantly compromising the quality of the image. This format is particularly useful for small icons, thumbnails, or images that need to be loaded quickly on devices with constrained resources.
