GetActionRemotePageDestination Method (GdPicturePDF)

In This Topic

Returns the remote destination information (a file, a page number and a page view with the used coordinates) of the specified GoToR action. This action jumps to a destination in another PDF file according to the defined destination parameters.

Parameters

ActionID: A unique action identifier specifying a required action object. You can obtain this identifier using these methods: GetViewerOpenActionID, GetBookmarkActionID, GetFormFieldActionID, GetAnnotationActionID or NewActionGoToR(PdfDestinationType,String,Boolean,Int32,Single,Single,Single,Single,Single).
Please ensure that the type of the action object specified by this identifier is exactly the PdfActionType.ActionTypeGoToR, otherwise the method will fail. You can check the type of the required action object using the GetActionType method as it is shown in the example below.
DestinationType: Output parameter. A member of the PdfDestinationType enumeration. Sets up a particular view of a destination to jump specified by the this action.
FilePath: Output parameter. The file path in which the destination is located.
NewWindow: Output parameter. Specifies whether to open the destination document in a new window. If the returned value is false, the destination document replaces the current document in the same window.
Page: Output parameter. The destination page number.
Left: Output parameter. The horizontal (left) coordinate of the document window's position according to the used DestinationType mentioned above. The value of this coordinate is expressed in the currently set units according to the currently used coordinate space, see the Remarks section below.
Bottom: Output parameter. The vertical (bottom) coordinate of the document window's position according to the used DestinationType mentioned above. The value of this coordinate is expressed in the currently set units according to the currently used coordinate space, see the Remarks section below.
Right: Output parameter. The horizontal (right) coordinate of the document window's position according to the used DestinationType mentioned above. The value of this coordinate is expressed in the currently set units according to the currently used coordinate space, see the Remarks section below.
Top: Output parameter. The vertical (top) coordinate of the document window's position according to the used DestinationType mentioned above. The value of this coordinate is expressed in the currently set units according to the currently used coordinate space, see the Remarks section below.
Zoom: Output parameter. The zoom factor to use when displaying the destination page according to the DestinationType configuration. The return value of 1 means 100% zoom, 2 means 200%, 0,5 for 50%, etc. The value of 0 means that the current zoom value should remain unchanged.

Return Value

A member of the GdPictureStatus enumeration. If the method has been successfully followed, then the return value is GdPictureStatus.OK. We strongly recommend always checking this status first.

If the action object specified by the action identifier is not of the type PdfActionType.ActionTypeGoToR, the reason for the method's failure is GdPictureStatus.InvalidParameter.

Remarks

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

All values of the coordinates are expressed in the current units defined by the SetMeasurementUnit method according to the current coordinate space defined by the SetOrigin method.
