I have a problem with my PDFs. They have a default font, Helvetica. This font is unused, but I need to develop a script that automatically deletes this font.
After asking two questions:
Unset PDF font with script
xhtml2pdf doesn't embed Helvetica
I finally discover iText. I've been trying to work with this library, and I made a few successful tests with Unembeding Fonts (example). But I can't find anything about deleting a whole font from de PDF.
Thanks a lot
