Hi.

I m using iTEXT.jar for barcode integration.

We have framework through which we generate pdf files.We hv predefined pdf templates and on the fly we add data to it to create the resulted pdf.Now i m adding barcode to this resulted pdf.But the new pdf does not contain the original data,but shows the template with barcode.ie.data is lost.

Can u help me to find out why?

I m attaching my code snippet with comments.

    private String createBarcode()throws PdfException{
        String barcodedPdfName = getFileLocation();
        PdfImportedPage page;
        int rotation;
        int i = 0;

try {
PdfReader reader = new PdfReader(getTempPdfName()); //already created pdf with data

            int n = reader.getNumberOfPages();
            Document document = new Document(reader.getPageSizeWithRotation(1));
            PdfWriter writer = PdfWriter.getInstance(document, new FileOutputStream(barcodedPdfName)); //shld write the contents of the prev generated pdf with barcode

document.open();
PdfContentByte cb1 = writer.getDirectContent();

Image img = barcodeViewDecorator.getBarcode().createImageWithBarcode(cb1,Color.black, Color.blue);
img.setAbsolutePosition(defaultBarcodeView.getX_coordinates(),defaultBarcodeView.getY_coordinates());

            if(defaultBarcodeView.isMultiplePageBarcode()){
                while (i < n) {
                    i++;
                    document.setPageSize(reader.getPageSizeWithRotation(i));
                    document.newPage();
                    page = writer.getImportedPage(reader, i);
                    rotation = reader.getPageRotation(i);
                    if (rotation == 90 || rotation == 270) {
                        cb1.addTemplate(page, 0, -1f, 1f, 0, 0, reader.getPageSizeWithRotation(i).height());

                    }
                    else {
                        cb1.addTemplate(page, 1f, 0, 0, 1f, 0, 0);
                    }
                    document.add(img);

}

            }else{
                page = writer.getImportedPage(reader,1);
                rotation = reader.getPageRotation(1);
                if (rotation == 90 || rotation == 270) {
                    cb1.addTemplate(page, 0, -1f, 1f, 0, 0, reader.getPageSizeWithRotation(i).height());

                }
                else {
                    cb1.addTemplate(page, 1f, 0, 0, 1f, 0, 0);
                }

                document.add(img) ;
            }
            document.close() ;

        } catch (IOException e) {
            throw new PdfException(e.getMessage() );
        } catch (DocumentException e) {
            throw new PdfException(e.getMessage() );
        } finally {
            return barcodedPdfName;
        }
    }

Thanks and Best Regards
