Collapse All Syntax| HRESULT PDFPAGE_EoClip () |
RemarksThis method sets the current path as the boundary for clipping subsequent drawings. The use of the clip operator may require some care, because clip operators do not use the current path. Also note that there is no practical way of removing a clipping path, except by using PDFPAGE_GStateRestore before clipping. This methods uses an even-odd rule for defining the "path inside".
Equivalent in new interface: IPDFDocument4::AlternateClip.
