He looked back at the screen. He needed to fix the graphics later, make them pretty again, design a new glossy vector shape to replace the ugly relic he had just resurrected.
| Specification | Requirement | Rationale | | :--- | :--- | :--- | | | SVG (Primary), PNG (Fallback) | SVG scales without distortion for multi-resolution displays; PNG ensures compatibility with legacy panels. | | Color Palette | ANSI/ISA-101 Compliant | Red = Alarm/Critical, Yellow = Warning, Green = Running/Auto, Gray = Stopped/Idle, Blue = Acknowledged. | | Resolution | 64x64, 128x128, 256x256 | Provide three raster sizes to optimize memory usage on older panels. | | State Layering | 4 states per asset (Normal, Fault, Acknowledge, Command) | Allows dynamic state changes without loading new images. | hmi image library
A high-quality image library is built on High-Performance HMI principles. It uses shapes and colors deliberately to indicate status without creating visual clutter. A standardized library ensures that every alarm indicator flashes at the same rate and every interlock state is represented identically, allowing operators to scan screens quickly and spot anomalies.
