EndPath Method (GdPicturePDF)

In This Topic

Ends the current path object, that means empties the current path, defined within a currently selected page of the loaded PDF document, without filling or stroking it. More precisely, this method sets the path-painting no-op operator "n". If the current sub-path is already closed, any other additional "n" operator does nothing (see PDF Reference, Section "Path Construction Operators"). This operator is mostly used with a clipping path operator.

Syntax

'Declaration
 
Public Function EndPath() As GdPictureStatus

public GdPictureStatus EndPath()

public function EndPath(): GdPictureStatus;

public function EndPath() : GdPictureStatus;

public: GdPictureStatus EndPath();

public:
GdPictureStatus EndPath();

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

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

For further assistance, please see the Path Construction and Painting section of the GdPicturePDF class in the Reference Guide, as well as the Path-painting Operators and the Clipping Path Operators sections in the PDF Reference.
