NewActionNamed Method (GdPicturePDF)

In This Topic

Creates a new action of the type Named. A named action is a simple action defined by its name that PDF viewer applications are expected to support. See the PdfActionNamed enumeration for the predefined named actions.

Syntax

Visual Basic
C#
Delphi
JScript
Managed Extensions for C++
C++/CLI

'Declaration
 
Public Function NewActionNamed( _
   ByVal Name As PdfActionNamed _
) As Integer

public int NewActionNamed( 
   PdfActionNamed Name
)

public function NewActionNamed( 
    Name: PdfActionNamed
): Integer;

public function NewActionNamed( 
   Name : PdfActionNamed
) : int;

public: int NewActionNamed( 
   PdfActionNamed Name
)

public:
int NewActionNamed( 
   PdfActionNamed Name
)

Parameters

Name: A member of the PdfActionNamed enumeration. Sets the destination of the action specified by its name.

Return Value

The unique action identifier of the newly created action of the type Named. The GetStat method can be subsequently used to determine if this method has been successful.

You can subsequently apply this identifier when creating actions using these methods: SetViewerOpenAction, SetBookmarkAction, SetAnnotationAction or SetFormFieldAction.

Remarks

This method is only allowed for use with non-encrypted documents.

It is recommend to use the GetStat method to identify the specific reason for the method's failure, if any.

Example

How to create a PDF document of 5 pages with 4 links on each page, while these links are associated with the predefined named actions.
