Do a full save instead of an incremental one. However, what version of the XMPToolkit are you using? I am quite sure that the current version will scan from the rear and not the front, for exactly this reason...
Leonard From: Ian Ashley [mailto:[email protected]] Sent: Friday, August 13, 2010 6:33 AM To: [email protected] Subject: [Podofo-users] XMP writing Dear all, With Dominik's help I have managed to add/replace XMP in a PDF using the following code // newXMP is a char * pointing to the new XMP, newXMPLen it is the length of the XMP PdfObject *xmpObj = podofoDoc->GetObjects().CreateObject("Metadata"); xmpObj->GetDictionary().AddKey(PdfName("Subtype"), PdfName("XML")); xmpObj->GetStream()->Set(newXMP, newXMPLen, TVecFilters()); // no filters are provided so that the XMP is output unencoded - this is what the Adobe apps do podofoDoc->GetCatalog()->GetDictionary().AddKey(PdfName("Metadata"), xmpObj->Reference()); podofoDoc->Write("aFile.pdf"); I found that this leaves the original XMP in the PDF and adds the new XMP at the end. This isn't a problem based upon the spec, the XMP found is used however the Adobe XMP library handles PDFs very crudely and returns the first XMP it finds. Is there any way to get PoDoFo to only write out the new XMP? Also is it possible to get the new XMP written near the start of the file rather than at the end? Thanks in advance, Ian
