I want to have a stamp brought to the front of PDF documents but still be able to read the document behind it. I have tried altering Opacity but no matter what I do the image is still not see through. I want to have the same effect as if I was in Acrobat and set Transparency to 35%. Is this possible?
In Stamp class there is a property named Opacity, using which you can set a float value to indicate the stamp object opacity. The value is from 0.0f and 1.0f, by default, the value is 1.0f. For more information please visit Opacity
