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 iimg file format is associated with Interleaf, a document processing system that was popular for technical publishing in the late 1980s and 1990s. Interleaf files, including those with the iimg extension, were used for creating and managing complex documents that contained text, images, and graphics. These files were part of a sophisticated desktop publishing system that supported advanced layout and formatting options, making it a preferred choice for professional documentation. However, with the decline of Interleaf and the rise of other publishing software, the iimg file type has become less common.
