Could we see the stack trace? PS: Your code would be much cleaner if you used PdfDictionary's getAs* methods. They handle the PdfReader.getObject(...) for you as needed.
> > PdfDictionary parent = > (PdfDictionary)reader.getPdfObject(1); Err... bad idea. Never look up objects by Object Number with hard-coded numbers. I realize you may have found the number programmatically, but there's still a better way: PdfDictionary parent = reader.getPageN(1); // for the first page, 1-indexed. > > PdfObject resources = parent.get(PdfName.RESOURCES); > > PdfDictionary resDict = (PdfDictionary) > >PdfReader.getPdfObject(resources); > > PdfObject xobjects = resDict.get(PdfName.XOBJECT); > > PdfDictionary xObjDict = (PdfDictionary) > >PdfReader.getPdfObject(xobjects); PdfDictionary restDict = parent.getAsDict(PdfName.RESOURCES); PdfDictionary xObjDict = resDict.getAsDict(PdfName.XOBJECT); The getAs* functions (PdfArray has a matching set) will return a null if the element is missing or if it's the wrong type. If you need to know which, you need extra code (such as the Old Method). And they automagically look up indirect references and check their type too. Not that it helps you with your problem. Err... I cannot find a "NullReferenceException" anywhere within iText. So I'd /really/ like to see that stack trace. --Mark Storer Senior Software Engineer Cardiff.com import legalese.Disclaimer; Disclaimer<Cardiff> DisCard = null; > -----Original Message----- > From: Felipe Roos [mailto:feliper...@yahoo.com] > Sent: Wednesday, July 14, 2010 7:59 AM > To: Post all your questions about iText here > Subject: [iText-questions] Res: Adding a PdfImportedPage into a > xobjectPdfDictionary - is this a good thing to do? > > Any update on this? > > Felipe Roos > http://www.linkedin.com/in/feliperoos > > > Achar desculpas para os nossos > defeitos não nos torna melhores > > > > ----- Mensagem original ---- > > De: Felipe Roos <feliper...@yahoo.com> > > Para: Post all your questions about iText here > ><itext-questions@lists.sourceforge.net> > > Enviadas: Quinta-feira, 10 de Junho de 2010 14:02:56 > > Assunto: Re: [iText-questions] Adding a PdfImportedPage into a xobject > >PdfDictionary - is this a good thing to do? > > > > > > 1T3XT info wrote: > > > Your requirement calls for a Proof of Concept in the form > > of an interesting > > > example on itextpdf.com.
