Transparency depends very much on the output driver and its settings. I have used it successfully with xdvipdfm, by way of the "opacity" optin in TikZ; but the resulting output files are version 1.5 PDFs which not every printer supports. If you're using some other driver (for instance, anything that goes to Postscript instead of PDF), or if your printer doesn't like transparency, there may be problems. It is possible to use Ghostscript to resolve the transparency (convert to a non-transparent PDF or Postscript file that still looks at it should) but it appears to accomplish that by rasterizing the file, which may not be suitable for your purposes. -- Matthew Skala [email protected] People before principles. http://ansuz.sooke.bc.ca/ -------------------------------------------------- Subscriptions, Archive, and List information, etc.: http://tug.org/mailman/listinfo/xetex
