Opto 22 offers a comprehensive image library specifically designed for their groov View HMI project platform, though many assets can be used elsewhere.

is an open‑source HMI framework built with C++ and QML, using Qt libraries as its foundation. It is cross‑platform, graphics API agnostic, and designed to integrate with automation projects. While it is a full HMI development environment rather than just a graphics library, its modern UI capabilities make it a strong option for projects already using Qt.

Free HMI graphics libraries can save development time and costs while providing a head start on creating visually appealing and user-friendly interfaces. When choosing a library, consider features such as cross-platform compatibility, customizability, ease of use, and community support. Some popular free HMI graphics libraries include Qt for Automation, FLTK, GTK+, wxWidgets, and Scada-LTS.
