- Description
- It is an icon image file used to show application icons in the macOS Finder and macOS dock. It contains one or several .PNG images and it supports 1bit and 8-bit alpha channels.
- 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.
