Q:
How do I set 100% zoom magnification in PDF?
Basically what I need is that a PDF viewer opens my document at 100% zoom magnification.
A:
You can tell the viewer to set the zoom to 100% default by setting document’s ‘OpenAction’:
doc.SetOpenAction(Action.CreateGoto(Destination.CreateXYZ(doc.GetPage(1), 0, 0, 1)));
The last parameter in CreateXYZ is the zoom factor (in rage 0…1). For more info please refer to PDFNet API Ref.
