High-Performance HMI image libraries use flat, 2D, grayscale designs.
An HMI image library is a collection of pre-designed, high-quality images and graphics specifically created for use in HMI applications. These libraries typically contain a wide range of images, including icons, symbols, charts, and other graphical elements that can be used to represent various industrial control and automation concepts. The images in an HMI image library are usually designed to be easily recognizable, scalable, and compatible with various HMI software platforms.
| Format | Best for | Transparency | Scalability | |--------|----------|--------------|--------------| | | Icons, symbols, buttons | Yes | Infinite (vector) | | PNG | Complex graphics, photos | Yes | Fixed (raster) | | BMP | Legacy HMIs | No | Fixed | | EMF/WMF | Windows-based HMIs | Yes | Good | hmi image library
An excellent HMI image library includes multi-state variants of the same asset. Ensure your library integrates cleanly with your software's tag linking so that: Dark gray icon Tag = 1 (Running): Light gray/muted green icon Tag = 2 (Faulted): Flashing red border or symbol overlay 5.

Many modern libraries, such as the Opto22 Free Image Library , offer scalable vector graphics (SVGs), which can be resized, animated, or modified without losing clarity. Key Considerations for Choosing an HMI Image Library The images in an HMI image library are
At its core, an is a database of vector and raster graphics tailored for specific industrial use. But modern libraries are dynamic. They include:
To get the most out of an HMI image library, follow these best practices:
Elements must have clean transparent layers so they blend seamlessly over your chosen background color. Best Practices for Implementing HMI Graphics
