Package: pdftk
Version: 1.41-3
Severity: wishlist
It would be nice if pdftk would allow to overlay different pages at the
same time, like a stamp but not limited to only one page.
Attached patch for example adds an multistamp command, so that different
pages are stamped with different pages. This is for example very nice
to add page numbers or other "corrections" on top of an existing
document. (getting the different pages out and stamping those and
concatenating everything back is both more complex and generates much
bigger files).
Hochachtungsvoll,
Bernhard R. Link
