How to add watarmark to pdf ? #240

Closed zsr228 closed 5 years ago

zsr228 commented 5 years ago

As title, In your fpdf_test.go , I can't find a function to add watermark to pdf ?

jung-kurt commented 5 years ago

To make a watermark that repeats on each page, use the SetHeaderFunc() method. This lets you draw anywhere on the page as long as you reset the X and Y values before leaving the header function so that normal content begins where expected.

Adding a watermark to a document is demonstrated in the TransformRotate example.
