I am using Pdf Writer to get the page (PdfImportedPage) and then converting
it to image for scaling. This image is finally added to the PdfContentByte.
But on this process i am missing the Pdf annotations. Please find the
attached input pdf (PdfAnnot.pdf) and generated pdf(final.pdf).
My Code:
--------
PdfReader pdfReader= **
pdfWriter = PdfWriter.getInstance(pdfDocument,new
FileOutputStream("C:/FINAL_Annot.pdf"));
pdfDocument.open();
//Lets consider pageN = 1
pageDic = pdfReader.getPageN(pageN);
pdfWriter.addToBody(pdfReader.getPdfObject(pageDic.get(PdfName.ANNOTS)) );
=> Throws NullPointerException
page = pdfWriter.getImportedPage(pdfReader, pageN);
image = Image.getInstance(page);
image.scalePercent(50);
image.setAbsolutePosition(0, 0);
pdfDirectContent.addImage(image);
