OK, I'm now using PdfSmartCopy. What I'm doing is sending
the output from the original PdfWriter to a ByteArrayOutputStream,
and I then read that using another PdfReader and write it
to a PdfSmartCopy. Works great; the files don't shrink quite
as much as with Acrobat 8, but pretty close.
I have one other question: PdfSmartCopy is a subclass of
PdfWriter, which made me think maybe I can simply replace my
original PdfWriter by a PdfSmartCopy, and thus avoid the
two-stage approach. However, when I do that, the addTemplate()
call does not seem to work (at the end, I get an exception
saying the document has no pages). When I use addPage()
instead, the template pages get copied to the PdfSmartCopy,
but then the text that I'm printing on top of the template
does not show up.
Is it possible to use PdfSmartCopy as a replacement for
PdfWriter somehow, or do I have to use the two-stage
approach?
Thanks for your help. Great product!

Subject: [iText-questions] Duplicated fonts in iText-generated PDF
Hi all,
I'm working on a report generator that uses iText to generate PDF
files. The
content of the individual pages is composed by first printing a
template,
which is read from another PDF using PdfWriter.getImportedPage()
followed by
PdfContentByte.addTemplate(); then, the actual data are printed on top
of
the template using the usual PdfContentByte methods. Repeat for each
page.
All this works fine, except for one thing: the final reports consist of
about 80% font data. Simply opening and then saving them in Acrobat
will
shrink them considerably, sometimes by more than 50%. Apparently, there
are
a lot of duplicated fonts in the generated PDFs, but I don't understand
how
they get there.
The templates I use for the individual pages do not contain any
embedded
fonts; when I use a font in the code that populates the data, I'll
create it
with the BaseFont.EMBEDDED flag, but from the Javadocs, it is my
understanding that those fonts should only get embedded once. Could it
be
the process of reading the templates that is causing the same set of
fonts
to be embedded over and over?
Thanks for any insights!
