   FitWidth = 1 
   FitHeight = 2 
   FitWidthBounds = 3 
   FitHeightBounds = 4 
   FitBounds = 5

Members

1	FitWidth	Fit the page width into the window.
2	FitHeight	Fit the page height into the window.
3	FitWidthBounds	Fit the window into the page width.
4	FitHeightBounds	Fit the window into the page height.

Remarks

The PDFPageFitType structure is used as the type for the PDFBookmark.TargetPageFitType, PDFInternalLink.TargetPageFitType and PDFInitialViewOptions.PageFitType properties. It is used to instruct external viewers on how to fit the page in the viewer window when this bookmark or internal link is activated or clicked.
