Hello all,
I'm loading a pdf with a form, filing in the form, and
adding it to my document. To do so, I'm using the
following code (suggested by Bruno):
PdfReader reader;
PdfStamper stamper;
ByteArrayOutputStream baos
RandomAccessFileOrArray model = new
RandomAccessFileOrArray("d:\model.pdf");
// first stamper
reader = new PdfReader(model, null);
baos = new ByteArrayOutputStream();
stamper = new PdfStamper(reader, baos);
form = stamper.getAcroFields();
form.setField("Date", "11/05/2005");
stamper.setFormFlattening(true);
stamper.close();
// copy content of first page
reader = new PdfReader(baos.toByteArray());
Document document = new
Document(reader.getPageSizeWithRotation(1));
PdfCopy writer = new PdfCopy(document, new
FileOutputStream("HelloWorldStampCopy.pdf"));
document.open();
writer.addPage(writer.getImportedPage(reader, 1));
// second stamper
//etc...
I want to add a barcode and to do so I've checked the
examples picked up the one named
AddWatermarkPageNumbers. Here the code I added right
before "stamper.close(); ":
Barcode128 shipBarCode = new Barcode128();
// preparing bar code here
Image imgShipBarCode =
shipBarCode.CreateImageWithBarcode(stamper.GetOverContent(0),
Color.BLACK, Color.BLUE);
imgShipBarCode.SetAbsolutePosition(10, 10);
stamper.GetOverContent(0).AddImage(imgShipBarCode);
stamper.Close();
And it doesn't work because stamper.GetOverContent(0)
returns null. Anyone know what am I doing wrong ?
For the record I've also tried to use the following
code right after "writer.addPage":
Barcode128 shipBarCode = new Barcode128();
// preparing bar code here
Image imgShipBarCode =
shipBarCode.CreateImageWithBarcode(writer.DirectContent,
Color.BLACK, Color.BLUE);
imgShipBarCode.SetAbsolutePosition(10, 10);
writer.Add(imgShipBarCode);
And in this case, it doesnt work either (even if i got
no error): there is no barcode on my pdf.
Thanking you in advance,
Fabio
