Hello Logan,
Thank you for the response.
When I try and call that method it seems to return a value only sometimes, where most of the times it returns null. I am on the latest version of PDFExpress, and if I call console.log(instance.docViewer) I can see its initialized as I can get the current page.
The top is logging the docViewer itself, the middle is the current page number called by docViewer.getCurrentPage() and the buttom is logging the docViewer.getExactViewportRegionRect()
I can see this is something that was just added in the new version. Let me know if there is anything I can do to test / get this working.
Thanks,
Eric Greavette
