Detailed description of issue
I want to preserve the custom rubber stamps that a user can create using the tool. I have created similar functionality for signatures but I don’t see events corresponding to signatureSaved and signatureDeleted in the documentation

Expected behaviour
I expected an event that I could add a listener to when the user creates a rubber stamp using the tool.

Does your issue happen with every document, or just one?
Every document

Link to document
N/A

Code snippet

const signatureTool = instance.Core.documentViewer.getTool('AnnotationCreateSignature');
signatureTool.addEventListener('signatureSaved', function(annotation){
    // Code for saving signatures
});
signatureTool.addEventListener('signatureDeleted', function(annotation){
    // Code for saving signatures
});

const stampTool = instance.Core.documentViewer.getTool('RubberStampCreateTool');
stampTool.addEventListener('rubberStampSaved', function(annotation){
    console.log('rubberStampSaved event');
});
stampTool.addEventListener('rubberStampDeleted', function(annotation){
    console.log('rubberStampDeleted event');
});

Hi there,

While the rubberStamp tool may not have the same events as the signature tool, you can use the stampsUpdated event which will trigger on custom stamp creation and delete.

For example:

const tool = instance.Core.documentViewer.getTool(
        'AnnotationCreateRubberStamp'
      );
tool.addEventListener('stampsUpdated', (e) => {
        console.log(e, 'stamp updated');
      });

best regards,
Kevin
