Specifies the PDF page fit type.
public enum PDFPageFitType  
public final class PDFPageFitType 
    extends java.lang.Enum<PDFPageFitType> 
public enum class PDFPageFitType  
class PDFPageFitType(Enum): 
   Default = 0 
   FitWidth = 1 
   FitHeight = 2 
   FitWidthBounds = 3 
   FitHeightBounds = 4 
   FitBounds = 5 
0Default Default mode. Do not change the page fit mode.
1FitWidth Fit the page width into the window.
2FitHeight Fit the page height into the window.
3FitWidthBounds Fit the window into the page width.
4FitHeightBounds Fit the window into the page height.
5FitBounds Fit the window into the page width and height.

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.
