Thanks for your suggest Stefan, but I can't get it to work.
This is what i tried:
pdf24-DocTool.exe -applyProfile -profile user/mywm -profileParam pdf-watermarkText "My Watermark custom text" test.pdf -outputFile test_mark.pdf
I also tried with -pdf-watermarkText with no luck.
Sw version 11.1.0
Am i doing something wrong?
Any further suggest?
