Adding a text watermark
I've learned how to add a watermark to a pdf.
<cfpdf action="addwatermark" image="NoteToSelf.png"
pages="1"
position="0,0"
showOnPrint="no"
source="my.pdf"
destination="#myDir#\new.pdf"
overwrite="yes"
opacity="10">
The way I read it, the watermark has to be an image. 开发者_开发技巧But NoteToSelf.png needs to be text that I've read from a database.
Q: How can I add text as a watermark?
Q: If I am required to use an image for the watermark, then how do I use the ImageNew tag to create an image of text?
ColdFusion 8.0.1 onwards you can supply text directly to the cfpdf tag:
<cfpdf action="addwatermark" position="10,10" text="I am the watermakr" source="pdfContent" rotation="90" foreground="yes">
If you are not on on 8.0.1 then you would need to use imageNew and the image write text functions and pass that in.
