- 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 Iris Graphics file type, commonly associated with the extension .iris, originates from Silicon Graphics for use on their workstations. It is designed for storing high-quality images, particularly in the field of computer graphics and 3D rendering. This file format is tailored to support complex visual data, accommodating a range of color depths and resolutions suitable for professional graphics work. Despite its specialized use, the Iris Graphics format is less common today, having been superseded by more versatile image formats.
