Display a base image and let the user place markers, annotations, or shapes on it. Useful for fields like "Where on the diagram is the fault?" or "Mark the damage areas on this photo".
Conditional options
None at field level — the base image is supplied by the underlying data.
What gets stored
A JSON structure describing each plotted point or shape with its coordinates and label. The base image is referenced separately so the annotations can be rendered on top of it when the row is viewed.
Common uses
- Field service forms — "plot the damage on this car diagram".
- Construction / surveying — annotate site photos with measurements.
- Medical / dental — mark areas of concern on body or tooth diagrams.
