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:
