In case the PDF is nothing more than a compilation of images,
there's a way to deal with it for editing:
step 1: disassemble
step 2: edit images
step 3: reassemble
The disassembling can be done with
% pdfimages source.pdf .
Then the files can be edited whatever tool you like, e. g. Gimp.
They often come out in PBM format.
Finally the images can be re-converted to PDF and combined to one
PDF file:
for IMG in .*.pbm; do
convert ${IMG} ${IMG}.pdf
done
pdftk .*.pdf output target.pdf
Note the ".*" prefix for the file specification: The images extracted
by pdfimages match that pattern (at least in the case I tested it for).
If they get other names than .0000001.pbm, change the approach
accordingly.
