i have another question,
i have a scanned document in pdf.
can i do stamp text as "underlay" function? i know it works for the overlay function.
===========================
Scanned document is contain the solid white background, if you use the "underlay" function to stamp your PDF file, the solid white background will cover the stamp, you will not able to see the stamp at all.
However, we suggest you may use -Opacity option to stamp your PDF file Opacity, for example,
//Transparent function
pdfstamp.exe -PDF "example.pdf" -o "opacity.pdf" -AT "VeryPDF Opacity" -FT "Arial" -P9 -FS100 -opacity50 -C#FF0000 -AI logo.jpg -opacity80 -P2 -AL -LW30 -opacity30 -LINEEX 100,100,200,200
