Hey,
Just wanted to clarify something. Can you pan around using PDF.js?
For instance the canvas that holds the pdf is inside a div tag that's
say 800x600 and the pdf has been zoomed in to 300% (thus not fitting
in the div), and I wish to pan to different areas of the pdf.
More specifically, there's a javascript that programmatically zooms in/
out and now I'm trying to have it also pan around.
>From the examples, when changing pages, there's a call to getViewport.
var viewport = page.getViewport(zoomLevel);
That got me thinking if it is possible to use that viewport to pan
around since the viewport has offsetCanvasX, offsetCanvasY.
Thanks in advance.
