Why?
I needed to "stamp" quite a bunch of PDF files with a large transparent text mark. The mark content depended on the PDF file name. I looked around and realised that I can't seem to be able to find anything that would help me get it done in Linux without major pain of some sort. So I decided to roll my own
What it does.
pdfwatermark allows you to add an arbitrary text line on the first page of
a given PDF file. You can also make the text of the watermark depend on the file
name.
Usage
$ python pdfwatermark.py [OPTIONS] FILENAME
Use --help to see the detailed list of options
Warning
By default, pdfwatermark watermarks the file in place. No way to
'unwatermark' it is provided.
Example
Example 1, "trivial"
python pdfwatermark.py -w "WATERMARK" file.pdf
Puts a large black text 'WATERMARK' somewhere on the first page of file.pdf
Example 2, "simple"
python pdfwatermark.py -w "WATERMARK" -c "#FF0000" -o 0.3 -x 200 -y 150 file.pdf
Puts a large transparent pink 'WATERMARK' at the given coordinates
on the first page of file.pdf
Example 2, "pdfwatermark in full glory"
python pdfwatermark.py -c "#FF0000" -o 0.3 -x 200 -y 150 -w "({})" -r "^(\d+).+$" -d meaning.pdf 42-file.pdf
Puts a large transparent pink '(42)' at the given coordinates
on the first page of the content of 42-file.pdf and saves the resulting content
as meaning.pdf
Todo
- add a possibility to add watermarks on pages other than first
- make sure it works nicely with paper formats other than DIN A4
- handle (at least some) errors
