\t: Local time 10:10:10

\D: Local date  30-12-2003

  • We should input the color like this: pdfstamp.exe -PDF "example.pdf" -o "16.pdf" -AT "\d\n\t" -p7 -c255 -mlr70 -mtb-50

-AT: the order for creating a Text Stamp

\n: New line. Use for multi-line stamps like,

Sample stamp, line1

Sample stamp, line2

Sample stamp, line3

-P7:Stamps on the Left-Bottom of the page. This is for the stamp position. You can also put it on the center, Top-Center of the page, Right-Bottom of the page or others according to your needs.

-c255: For the stamp color, red. If you like to use other colors, please use other parameters,like ,Green Color: –C65280, Blue Color: –C16711680 or others.

[-MLRn]:Offset from current position, n is an offset value, default n equal zero.
