Hi,
I am trying to add a annotation in an existing pdfbytearray and then sending
it for download.
Here is what I am doing
try {
ByteArrayOutputStream pdfOut = new
ByteArrayOutputStream();
InputStream pdf = new ByteArrayInputStream(pdfBytes);
PdfReader reader = new PdfReader(pdf);
com.lowagie.text.Document document = new
com.lowagie.text.Document(
reader.getPageSize(1));
PdfWriter writer = PdfWriter.getInstance(document,
pdfOut);
int n = reader.getNumberOfPages();
writer.open();
document.open();
PdfImportedPage page;
PRAcroForm form = reader.getAcroForm();
if (form != null) {
//copy.add(reader);
}
//HASH MAP CONTAINS THE LIST OF ANNOTATIONS WHICH I WANT TO ADD
List<HashMap<Integer, Annotation>> list = new
ArrayList<HashMap<Integer,
Annotation>>();
com.lowagie.text.Annotation a1;
//CURRENTLY I HAVE HARD CODED THE RECTANGLE BOUNDS
for (int i = 1; i <= n; i++) {
page = writer.getImportedPage(reader, i);
list = getAnnotationsPerPage(annotations,
page.getHeight(), i);
for (HashMap<Integer, Annotation> map : list) {
for (Object key : map.keySet()) {
writer.addAnnotation(
PdfAnnotation.createText(writer,
new
Rectangle(200, 280, 220, 300),
"Comment",
StringUtils.deleteHTMLTags(map.get(key).getDescription()), false,
"Comment"));
}
}
Image instance =
Image.getInstance(writer.getImportedPage(reader, i));
document.add(instance);
}
writer.close();
pdfOut.flush();
pdfOut.close();
document.close();
return pdfOut.toByteArray();
} catch (Exception de) {
de.printStackTrace();
}
MY PROBLEM: I am able to add the annotations but a new page is also getting
added in the final PDF after the page where annotation is added also the
document size is getting messed up :|
