I am using pdftron WebViewer latest version. we needs to functionality Save and delete rubberstamp in database .
we are using below Event
instance.Core.documentViewer.getToolModeMap().AnnotationCreateRubberStamp.addEventListener(‘stampsUpdated’, customStamps ,False));
But we are facing issue getting Id which we need to deleted base on delete icon click by user.
I have investigated into the source code but I found that it’s currently not possible right now. You need to track the all the custom stamps yourself so that you can know which one was delete.
I have added the requirement for better API to our backlog and our product will review it later.
