PDF autozoom 作者： thmeier

When studying with PDFs for university I found myself constantly adjusting the zoom level manually depending on the page orientation of the PDF, thus this extension!
Vertical orientation as often used for written course notes, the zoom is automatically set to page-width, which facilitates reading text.
Similarly, for horizontal orientation, often used in course slides , zoom is set to page-fit, in order to have the complete overview.
