PDFViewCtrl's page view mode controls the default zoom level of pages and documents. New documents will automatically open at the zoom level specified by the mode.
PTPDFViewCtrl supports the following page view modes:
|Page view mode||Description||Screenshot-portrait||Screenshot-landscape|
|The zoom is set so that the entire page is visible without scrolling.|
|The zoom is set so that the page's width matches the viewer's width.|
|The zoom is set so that the page's height matches the viewer's height.|
|The viewer's zoom is not adjusted based on the page. (Unavailable in non-coninuous page presentation modes.)|
