37. Stamping form over
documents
• pdftk is an open-
source pdf utility that
works on the command
$ for file in `ls
line.
*_0??.pdf`; do
> pdftk form.pdf
• The pdftk invocation
makes the test file a
multibackground $file
output `basename
background for the
$file .pdf`_form.pdf; form and creates a new
> done file
• The for loop in the
bash shell cycles over
all pdfs sequentially
numbered

38. Other methods for
stamping
documentclass{article}
usepackage{tikz}
usepackage[pdftex]{eforms}
• Use TikZ to include the
scanned page and
begin{document}
begin{tikzpicture} form elements
[remember picture,overlay]
node at (current
page.center) { • Do this once per page
includegraphics[page=1]
{scanned_quiz}
};
• scriptable
% ... form stuff ...
end{tikzpicture} • Can also do a
clearpage watermark in Acrobat
