Hi, I'm trying to add some transparent text to an existing PDF, but I'm having some difficulty finding out how to add a GraphicsState for the alpha transparency settings. It seems that I need to be able to both add an ExtGraphicsState to the page's GraphicsState directory and then reference this. Does anyone have any examples along these lines that I can look at (e.g. anything involving ExtGraphicsState for writing to a PDF).
Thanks in advance Steve
