Hi, I need some new type of annotation, for example, TriangleAnnotation or HexagonalAnnotation. I would rather derive the new type from AnnotationBase than from CustomAnnotation, because I need more control points than one. what shall I do?
The best thing to do is to inherit or use a BoxAnnotation and change the template. We have an example here:
This will give you control points at all four corners.
Let me know if this helps!
