[Ipe-discuss] Script to export all views from all pages of the Ipe drawing

[Nathaniel Cunningham]

Wojtek,
Don't forget that Ipe stores its own extra data in PDF files, in order that
they can be opened again by Ipe. From the manual at
http://ipe.otfried.org/manual/manual_2.html:
"[PDF] files created by Ipe contain a special hidden stream that describes
the Ipe objects. (So if you edit your Ipe-generated PDF file in a different
program such as Adobe Acrobat, Ipe will not be able to read the file again
afterwards.)"

I don't know if that accounts for all the size difference you're seeing,
but you can test it by opening and saving the PDF with some other program.
If that takes care of the size difference, maybe you could add a step in
your script where some other program reads and saves the PDF?
