- 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 TG4 file type is associated with Tiled Group 4, a format used primarily for storing black and white (monochrome) images. It utilizes the Group 4 compression method, which is a form of TIFF (Tagged Image File Format) compression that is particularly efficient for scanning and storing documents, blueprints, and detailed line art in a compact file size without loss of quality. TG4 files are suitable for archiving or transmitting detailed images where retaining exact detail is crucial. They are commonly used in industries that require high-quality document imaging and archival, such as legal, engineering, and medical fields.
