All,
I was hoping for a quick sanity check here. I've got my code working, but I
want to make sure I haven't missed an optimizations.
Quick Description:
I have an existing PDF form with named fields. The form does have a
watermark that I added, but the rest of it was created in Acrobat. (i think)
The users of my app select one to N number of items.
For each item selected, a form is filled out and merged with the other to
result in an N length pdf.
Concerns:
I've got this working but the file seems a little large ~5 megs for 50
items. It makes me think that somehow I should be able to have a single
"form", and each page would just exist as a collection of form values. Not
being a PDF expert though, my expectations might be too high.
That being said, is there any way I could improve the final size of this
file? Speed up the process? Make it more efficient? (Part the test has been
removed, assume everything needed is there. I was throwing Exception just to
get this code tested, the production version should be more appropriately
laid out.)
@Test
public void createPdfs() throws Exception {
InputStream is = new FileInputStream(FILE_PATH);
PdfReader original = new PdfReader(is);
PdfCopyFields allDocs = new PdfCopyFields(new
FileOutputStream("C:\\pdftest\\testCONCAT.pdf"));
ByteArrayOutputStream baos = new ByteArrayOutputStream();
for (Items dd : list) {
// do the following for each target
PdfReader readerCopy = new PdfReader(original);
readerCopy.removeUsageRights();
baos.reset();
PdfStamper stamper = new PdfStamper(readerCopy, baos);
AcroFields form = stamper.getAcroFields();
form.setField("docNumberAndSuffix", dd.getMessage());
stamper.setFormFlattening(true);
stamper.close();
allDocs.addDocument(new PdfReader(baos.toByteArray()));
}
allDocs.setFullCompression();
allDocs.close();
}
Thanks in advance all.
