Usage

This tool provides two functionalities:

1. PDF Merger merging two PDF files into one,
2. PDF Editor editing a PDF file by adding a watermark and/or timestamp.

PDF Merger

This script merges two PDF files into one single PDF file. To merge two PDF files, run the script from the command line by providing the paths to the two input PDF files and the desired output PDF file name

python3 pdf-tools.py merge input1.pdf input2.pdf output.pdf

Replace input1.pdf and input2.pdf with the filenames of your PDF files you want to merge, and output.pdf with the filename you want the merged PDF to be saved to.

PDF Editor

To edit a PDF file by adding a watermark and/or timestamp, run the script with the following command:

python3 pdf-tools.py edit --watermark "WATERMARK TEXT" --opacity 20 --font_size 38 --timestamp input1.pdf output.pdf

Replace input1.pdf with the filename of your PDF file you want to edit, and output.pdf with the filename you want the edited PDF to be saved to. Adjust the watermark text, opacity, and font size as needed. Add --timestamp if you want to include a timestamp on each page.

Known limitations

The watermark is added at the center of the page rotated anti-clockwise by 90 degrees and shifted down by a static value. The location and font size for timestamp is not configurable.
