PDF is pretty efficient when it comes to reusing objects. If your pages
have many of the same objects that recur from page to page, when you split
the pages up, each one of your new pdfs will have the reused objects.
Depending on the objects that get reused, this can have a dramatic result on
splitting pdfs.

Subject: [iText-questions] Splitting into single pages size problem
Hi,
I am using itext 2.0.4 to split PDFs with multiple pages into single pages.
I am finding that the size of single page PDF is unexpectedly large. The
initial PDF is 50MB, and most of the pages are around 10MB. The PDF has
750 pages, so the resulting size is considerably larger than the
original (7500MB!).
It is only some PDFs that are affected. I was wondering if anyone has
seen similar problems, or has any idea what might be happening.
The code I am using is as follows (error handling ommitted).
...
PdfReader reader = new PdfReader(pdfInputStream);
int endPage = reader.getNumberOfPages();
for (int currentPage = 1; currentPage <= endPage; currentPage++) {
Document document = new
Document(reader.getPageSizeWithRotation(currentPage));
PdfSmartCopy copy = new PdfSmartCopy(document,
getSinglePdfOutputStream(currentPage));
copy.setFullCompression();
document.open();
PdfImportedPage page = copy.getImportedPage(reader, currentPage);
copy.addPage(page);
document.close();
}
...
Regards,
Will.
