DocumentPageFitType Enumeration

Summary

Specifies how to fit the page when an internal link is invoked.

Syntax

C++/CLI

Java

Python

[SerializableAttribute()] 
[DataContractAttribute()] 
public enum DocumentPageFitType

public [SerializableAttribute,  
   DataContractAttribute] 
   enum class DocumentPageFitType sealed

public enum DocumentPageFitType

class DocumentPageFitType(Enum): 
   None = 0 
   Fit = 1 
   FitAlways = 2 
   FitWidth = 3 
   FitHeight = 4

Members

0	None	No fitting. Use Position and ZoomPercent if they have valid values.
1	Fit	Show the whole page in the view. If the page is smaller, do not zoom in.
2	FitAlways	Show the whole page in the view. If the page is smaller, zoom in to fit.
3	FitWidth	Fit the view so the whole width of the page is visible.
4	FitHeight	Fit the view so the whole height of the page is visible.

Remarks

DocumentPageFitType is used as the value for DocumentLinkTarget.PageFitType.
