   Hi 
I tried to add a water mark to my PDF file using this example:

I am using png file for watermark, and the problem is the white background of png file covers the original contents.

What am I doing wrong?

Thanks

	Hi Ag, so you didn't set a transparency value. If you think "Hey... i'm using a png with transparency" you should read here about what's possible and what not: http://www.quickpdflibrary.com/faq/how-do-i-add-an-image-and-make-it-transparent.php
	Cheers, Ingo
