PDF: zoom with scroll wheel and pan


Is it possible to set a PDF document using Adobe Acrobat 9 or 10 so that:

  • Using the mouse's scroll wheel will zoom
  • Holding left-click will pan

It's an intuitive interface, kind of like Google Maps, that I would use with some PDFs...

Accepted Answer

Acrobat has similar behavior built in. If you scroll mousewheel while holding Ctrl (on Windows, not sure the Mac key), you will zoom in and out. If you hold Space while click-dragging, you will pan around the document.

(This is how it behaves in Acrobat X. I believe the behavior is the same in older versions though I don't have any present to test.)

If I'm understanding the question correctly, you want to know if it's possible to set this as a document behavior. Zoom and pan behaviors are controlled by the reader (whether Adobe Reader or Acrobat or some 3rd party solution), so in a regular PDF that would not be possible.

You could embed a SWF that had this capability, though. You would have to create it with Flash Professional and include it in the PDF either via InDesign or directly in Acrobat. If you have access to a good javascript coder, that might be another approach. It's not something you can do natively in the Acrobat UI.

Always be aware, though, that very few PDF readers implement all of the PDF specification, so your results are likely to be unpredictable at best and most likely would work only in Adobe Reader.
