) : PdfOcgState;
'Declaration
Public Function GetOCGPrintState( _
ByVal As Integer _
) As PdfOcgState
Parameters
- OCGId
- The unique identifier of the required OCG entry. You can obtain this identifier using the GdPicturePDF.GetOCG method.
Return Value
A member of the PdfOcgState enumeration. The value of the Print state setting. The
GdPicturePDF.GetStat method can be subsequently used to determine if this method has been successful.
How to find out the Print state of the specified layer and some other layer's properties.
