setCustomDrawHandler not firing dynamically unless performing explicit action

Technical Support

Product: PDFTron WebViewer

Product Version: 8.12.0

Please give a brief summary of your issue:
(Think of this as an email subject)

When I set setCustomDrawHandler and place an annotation, the annotation is drawn correctly. When I move/modify the annotation, setCustomDrawHandler does not trigger. If I resize the annotation within the viewer (non programmatically), setCustomDrawHandler fires on movement and modification. I would like to have that happen from the jump.

Please describe your issue and provide steps to reproduce it:
(The more descriptive your answer, the faster we are able to help you)

  1. Set setCustomDrawHandler after initializing webviewer.
  2. Programmatically create an annotation.
  3. Move annotation around. Observe no setCustomDrawHandler being called.
  4. Manually resize the annotation, or change opacity, etc.
  5. Move annotation around. Observe setCustomDrawHandler being called many times.

Please provide a link to a minimal sample where the issue is reproducible:

Hi, I was able to resolve this by using a CustomAnnotation. Thanks!
