My project requires our end users to be able to define custom "hot spots" on an image that are then clickable in another area of our application.

To achieve this I'm trying to use the Leadtools annotations SDK (.Net) but I'm running into some difficulties.

I need to be able to do a few things:

- restrict the options on the toolbar so only the free hand hotspot annotation is available
- capture events when an annotation is added or removed
- enumerate all free hand hotspot annotations

I can't quire figure out how to achieve these; I've looked at the AfterObjectChanged event of the AnnAutomation object but it doesn't tell me if an annotation is being deleted, and I still can't figure out where the collection of annotations is.

Help?

Please see this forum post that shows how you can modify the annotation toolbar and remove some of its buttons:
