'Declaration
 
Public Overloads Function SaveToFile( _
   ByVal FilePath As String _
) As GdPictureStatus

public GdPictureStatus SaveToFile( 
   string FilePath
)

public function SaveToFile( 
    FilePath: String
): GdPictureStatus;

public function SaveToFile( 
   FilePath : String
) : GdPictureStatus;

public: GdPictureStatus SaveToFile( 
   string* FilePath
)

public:
GdPictureStatus SaveToFile( 
   String^ FilePath
)

Parameters

FilePath: The file path where the currently loaded PDF document will be saved. If the specified file already exists, it will be overwritten.
You are allowed to overwrite the currently opened PDF document only if the document has been loaded into memory setting the LoadInMemory parameter to true in the previously called GdPicturePDF.LoadFromFile method.

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.

Remarks

You have to specify a full file path with the correct file extension, which is "pdf".

This method requires the PDF Processing component to run.
