How do you access the PDF Document before it is rendered? #73

I have the requirement of updating some annotation fields before the page is rendered in order to prepopulate them with certain values. Using this library, is it possible?

Right now I am using the Viewer component. I assume there is no way as it is now to do that. If that is true, would the best route be to modify the viewer code directly?

@bpetty-formfast You may look into the viewerjs and pdfjs files directly for this. This component is indented for viewer as is. Editing is out of scope.

A search on viewerjs yielded these line

eventBus.on('pagerendered', webViewerPageRendered);
    eventBus.on('textlayerrendered', webViewerTextLayerRendered);

Also I saw beforedraw function.

Hope this helps.
