Thank you very much. I just downloaded the book, and will go through Chapter 12. I hope that you don't mind my asking further questions as I get into the OCG example.

Use OCG. There's an example of such a map in chapter 12 of the book "iText in Action". First the map looks like a raster image, when the user zooms in, he says a vector image. There's a "Layers pane" on the left he can use to enable/disable layers. This pane could easily be replaced by links (as described elsewhere in the book). -- This answer is provided by 1T3XT BVBA ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
