Gents,
I use PdfWriter to import pages as such:
PdfImportedPage page = writer.GetImportedPage(reader, pageNumber);
writer.DirectContent.AddTemplate(page, ... );
This wraps the page in an XObject Form that is then referenced by the Page
being generated in the output.
What I would like to do is to add a /Name entry to the XObject Form
dictionary to indicate to a PostScript conversion engine that the Form
should cached as opposed to being replicated each time it's being referenced
by a page. I was hoping to do something like:
PdfStream stream = page.GetFormXObject(-1);
stream.Put(new PdfName("Name"), new PdfName("CacheThisForm"));
but the protection level does not allow that, and even if it did, I would
get a private copy with the Name added but no changes in the actual output.
It's easy adding dictionary entries on the PdfReader side and have them
being preserved, but it escapes me how to do this on a template being added.
Any ideas on how this can be accomplished?
Thanks - Gylfi
