I'll take a look at it after work.
I tried the following code:
//A file containing an image xobject named /Im0
PdfReader reader = new PdfReader(/*somefile.pdf*/);
//A 1-page file to be added into the original file
PdfReader fileToAdd = new PdfReader (/*someotherfile.pdf*/);
PdfStamper stamper = new PdfStamper(reader, new
FileOutputStream(args[2]));
//The name of the entry in the xobject dictionary
PdfName name = new PdfName("Im0");
//The page object where that image is
PdfDictionary parent = (PdfDictionary)reader.getPdfObject(1);
PdfObject resources = parent.get(PdfName.RESOURCES);
PdfDictionary resDict = (PdfDictionary)
PdfReader.getPdfObject(resources);
PdfObject xobjects = resDict.get(PdfName.XOBJECT);
PdfDictionary xObjDict = (PdfDictionary)
PdfReader.getPdfObject(xobjects);
//import the first page of the fileToAdd
PdfImportedPage page = stamper.getImportedPage(fileToAdd,1);
//following
http://itextpdf.com/examples/index.php?page=example&id=285 sample
Image img = Image.getInstance(page);
PdfImage pdfImage = new PdfImage(img, "", null);
PdfIndirectObject imgRef = stamper.getWriter().addToBody(pdfImage);
xObjDict.put(name, imgRef.getIndirectReference());
stamper.close();
Using Itext 2.1.7, it crashes in the creation of the PdfImage object with a
NullReferenceException.
BTW, thanks in advance for you support on this.
