Public Shared Function GetDefaultPicture( _
   ByVal type As AnnRubberStampType _
) As AnnPicture
Visual Basic (Usage)Copy Code
Dim type As AnnRubberStampType
Dim value As AnnPicture
 
value = AnnRubberStampObject.GetDefaultPicture(type)
C# 
public static AnnPicture GetDefaultPicture( 
   AnnRubberStampType type
)
C++/CLI 
public:
static AnnPicture^ GetDefaultPicture( 
   AnnRubberStampType type
) 

Parameters

type
An AnnRubberStampType value that represents the type of the rubber stamp.

Return Value

An AnnPicture class that defines the picture for the AnnRubberStampType specified by type.

Example

This sample does the following:

  1. displays the default rubberstamp picture and displays it
  2. restores original rubberstamp picture and displays
  3. changes to new style and displays

Remarks

Use the SetDefaultPicture method to change the default picture used by the AnnRubberStampObject objects. Use the GetUseOriginalPicture and SetUseOriginalPicture methods to control whether an AnnRubberStampObject will use the default or original picture for a certain type.

Requirements

Target Platforms: Silverlight 3.0, Windows XP, Windows Server 2003 family, Windows Server 2008 family, Windows Vista, Windows 7, MAC OS/X (Intel Only)
