It was the wrong size. The aspect ratio was 4:3, but the new widescreen monitors were 16:9. If he imported it, it would stretch. It would look distorted.
You can browse the library through several official NASA and Stanford University portals:

When selecting images for a library, the file format matters significantly.
| Challenge | Description | |-----------|-------------| | | Red “stop” icon from different sources may have different shapes, colors, or animation behaviors. | | Format fragmentation | Projects mix PNG, BMP, SVG, WMF, and proprietary symbol formats (e.g., .sym). | | Poor scalability | No central versioning → multiple outdated copies of the same pump symbol. | | Loss of metadata | Image files lack tags (pressure rating, fluid type, safety class). | | Device constraints | Some HMIs have limited color depth or memory; generic images fail at runtime. | It was the wrong size
The HMI Image Library was a messy place, a graveyard of design trends and forgotten prototypes. But in that mess, Elias had found the one thing that mattered: a working lever in a world of broken buttons.

The library translates raw sensor data into several visual formats:
