I works for all PDF files in the sense that it adds new content under the existing content. That doesn't necessarily mean yo will actually see this content. For instance: - the new content is added outside the page area that is visible in your PDF viewer - the new content is hidden by some opaque objects (a rectangle filled with color, an image,...) > I tried on several PDF files, > one downloaded from Adobe, > one generated by myself using Distiller, > and one generated by myself using Bullzip > PDF print driver. > The "over" part works fine. > But watermark graphic that is put > on the "under" content does not show. > It is obscured by the original content.

This has been discussed before. One of the best answers was to add the image on top of the existing content, but use transparency to make the image transparent (so that the content underneath the image is still visible). This is explained in chapter 11 of the book. br, Bruno ------------------------------------------------------------------------- Take Surveys. Earn Cash.
