I'm apparently doing something wrong. I'm trying to append some content
directly to the page's existing content-stream (it's already formatted
with the correct operators & operands, because I removed it previously).
Not only is the updated content not being written, but my simple removal
of one docInfo property is also ineffective. However, a PDF [copy] is
being written, and no exceptions are being thrown.
Here's a snippet of the java method:
if (docinfo.containsKey("IP_Text")) {
String ipText = docinfo.get("IP_Text");
docinfo.remove("IP_Text");
PdfDictionary page = reader.getPageN(1);
PRStream stream =
(PRStream)page.getAsStream(PdfName.CONTENTS);
byte[] contentBytes = PdfReader.getStreamBytes(stream);
baos = new
ByteArrayOutputStream(contentBytes.length + ipText.length());
baos.write(contentBytes);
baos.write(ipText.getBytes());
baos.flush();
baos.close(); //unnecessary?
stream.setData(baos.toByteArray());
copy = new PdfStamper(reader, new
FileOutputStream(copyFilename));
copy.setMoreInfo(docinfo);
...
copy.close();
