I am combining 50+ different single page PDF files together that have
been produced from various places (Excel, acrobat, word, etc). The
files combine together no problem, the only issue is that the filesize
is 10-11mb while if I combine the same set of files together using the
acrobat tool the end result is only 1mb.
Am I missing some sort of optimization method within iText to produce
a smaller PDF?
Here is a rough outline of the method I am using that I got out of
examples from the iText in action book:
writer = new PdfWriter.getInstance();
foreach (page) {
PdfReader reader = new new PdfReader(page.getContentsByteArray());
PdfImportedPage importedPage = writer.getImportedPage(reader, 1);
PdfContentByte cb = writer.getDirectContent();
cb.saveState();
cb.doSomeScalingAndAffineTransForms();
cb.addTemplate(importedPage,0,0);
cb.restore();
writer.freeReader(reader);
}
Is the large file size due to the fact I am freeing the reader after I
read each page so the writer is unable to re-use resources like
embedded fonts? Or are there other ways I can optimize the final
output file size?
Thanks.
