问题
I am embedding a PDF using <object> into a page. I want the PDF to display as only a portion of the page, and I would like for the whole first page to show in the visible area (similar to an image snapshot of the first page). I am working with the PDF open parameters and I see various examples for adjusting zoom and view, for example:
http://example.org/doc.pdf#page=3&zoom=200,250,100http://example.org/doc.pdf#page=72&view=fitH,100
I can't get these to work. When I change the page parameter, the page displayed changes, but I cannot figure out how to adjust the view.
JS Fiddle demo showing the issue. And an example of the embed code:
<object width="300" height="375" type="application/pdf" data="file.pdf?#page=2&zoom=100">
<p>Message for non-compatible browsers</p>
</object>
I saw this question: Initial Zoom Parameter for PDF Object in HTML5, but the answers did not help me.
