Is there a way to exclude a type of annotation from history

[lakshan]

In my application, I programmatically generate a text annotation at the bottom of every annotation. Is there anyways to exclude it from annotation history. I don’t want that text to be changed when user click on undo

Hello lakshan,

Currently we dont have a standardized way to do this, however here are the links to the documentation on the AnnotationHistoryManager:

• Annotation History | Documentation
• PDFJS Express WebViewer Class: AnnotationHistoryManager

We have a task in our next sprint’s backlog to create better APIs to interact with the annotation history manager.
