I want to merge 2 pdf documents using iText in java, one of the pdfs is created at runtime while the other is an existing pdf that I read in and using the PdfStamper function stamp an image onto it. I want to then merge these two pdfs and display them using a servlet.
I want to know if this is possible and how to do it.
I have no problem creating or stamping them separately but I just can't seem to figure out how to merge them.
Thanks
I suppose this code can help you. You would have to import IText.Jar for this
public static void doMerge(List<InputStream> list,
OutputStream outputStream) throws DocumentException,
IOException {
Document document = new Document();
PdfWriter writer = PdfWriter.getInstance(document, outputStream);
document.open();
PdfContentByte cb = writer.getDirectContent();
float k = 0;
for (InputStream in : list) {
PdfReader reader = new PdfReader(in);
for (int i = 1; i <= reader.getNumberOfPages(); i++) {
// document.newPage();
//import the page from source pdf
PdfImportedPage page = writer.getImportedPage(reader, i);
//add the page to the destination pdf
cb.addTemplate(page, 0, 0);
System.out.println(page.getHeight());
}
}
outputStream.flush();
document.close();
outputStream.close();
}
