Syntax
Delphi
function TPDFlib.SetInformation(Key: Integer; Const NewValue: WideString): Integer;ActiveX
Function PDFlib::SetInformation(Key As Long, NewValue As String) As LongDLL
int DLSetInformation(int InstanceID, int Key, wchar_t * NewValue);Parameters
| Key | The property to set: 0 = PDF Version 1 = Author 2 = Title 3 = Subject 4 = Keywords 5 = Creator 6 = Producer 7 = CreationDate 8 = ModDate 9 = XMP dc:subject |
|---|---|
| NewValue | The new value of the specified property. |
When Key is 0, NewValue selects the full-save PDF target version. For PDF 1.3, 1.4, 1.5, 1.6, and 1.7 targets, SaveToFile, SaveToString, and SaveToStream keep the emitted file within that selected version. If the document still contains a feature that requires a newer PDF version, saving fails and LastErrorCode returns 602.
Return values
| 0 | The specified information could not be set. Use the LastErrorCode function to determine the reason for failure. |
|---|---|
| 1 | The specified information was set successfully |
