Convert HEIF to UIL

The High Efficiency Image File Format (HEIF) is a modern image format designed for superior compression efficiency and enhanced image quality. Originating in 2015, HEIF was developed by the Moving Picture Experts Group (MPEG) and utilizes the High Efficiency Video Coding (HEVC) codec to store image data. It supports a wide range of multimedia applications, including single images, image sequences, auxiliary image items, and non-image items, making it highly versatile for professional and consumer usage in various devices and platforms. Its ability to maintain high image quality while reducing file size significantly improves storage efficiency and accelerates data transmission.

The UIL file extension stands for User Interface Language and is associated with the X-Motif UIL Table. It is a plain text file format used by the UIL compiler to create user interfaces for the X Window System. UIL files define menus, buttons, dialog boxes, and other graphical user interface components. Introduced by The Open Group, this format allows developers to describe the initial state of a user interface, including widgets, resources, and callbacks. The UIL file is compiled into a UID file, which can be accessed by Motif Resource Management functions within an application.
