Feature Suggestion: Image Annotations #2586

mispranami commented 2 days ago

I suggest adding image annotation capabilities to OpenSeadragon. This feature would allow users to annotate images directly in the viewer, enhancing usability for applications like education and research.

Suggested Features: Annotation Types: Text, shapes, and freehand drawing. Management: Options to edit, move, or delete annotations. Styling: Customizable appearance (color, opacity). Collaboration: Multi-user annotations and commenting.

These are great features but definitely outside the scope of the core OpenSeadragon. There are already some plugins for some of these features:

Probably the most advanced is Annotorious:

Note that management and collaboration features require server-side technology.
