Hi,

Annotations in PDFJS Express always use Point, which is not the unit that’s being used in the bottom right measurement overlay.

Are you just wanting to get the value that’s shown in the measurement overlay? If this is the case you can just call `tool.annotation.getContents()`.

Best Regards,  
Zhijie
