Stamp (not watermark) PDF file

lukinbg · May 15, 2013

This script "watermark.ps" creates a watermark (=text in background) on each PDF page:

'<<
/BeginPage
{ gsave
/Helvetica_Bold findfont 72 scalefont setfont
.75 setgray 130 70 moveto 50 rotate Watermark show
grestore
} bind
>> setpagedevice

gs -q -dNOPAUSE -dSAFER -dBATCH -sOutputFile=output.pdf -sDEVICE=pdfwrite watermark.ps -f myfile.pdf

Any idea how to rewrite it to create a stamp (=text in foreground) on each PDF page?

Hi,

I dont know if it's late, but you could use /EndPage instead of /BeginPage to achieve that.

Something like this:

Code:

/watermarkText { (WATERMARK TEXT) } def
/watermarkFont { /Helvetica-Bold 72 selectfont } def
/watermarkColor { .75 setgray } def
/watermarkAngle { 45 } def

/pageWidth { currentpagedevice /PageSize get 0 get } def
/pageHeight { currentpagedevice /PageSize get 1 get } def
			
<<
	/EndPage {
		2 eq { pop false } 
		{
			gsave
			watermarkFont
			watermarkColor
			pageWidth .5 mul pageHeight .5 mul translate
			0 0 moveto
			watermarkText false charpath flattenpath pathbbox
			4 2 roll pop pop
			0 0 moveto
			watermarkAngle rotate
			-.5 mul exch -.5 mul exch
			rmoveto
			watermarkText show
			grestore 
			true 
		} ifelse
	} bind
>> setpagedevice
