Ben and Tyson: Callouts on images are very different than image maps. To get image callouts to work with docbook you have to use either Saxon or Xalan as they need extension packages written for the specific processors (the functionality does not work with XSLT 1.0 stylesheets)
These packages come as part of the stylesheet distribution under the extension directory. Pick the one that matches the processor you are using (I strongly suggest Saxon) and make sure that it is in your Java classpath. You can find more and better instructions in Bob's book: http://sagehill.net/docbookxsl/AnnotateListing.html#CalloutsGraphics Carlos On Mon, May 7, 2012 at 7:55 AM, ben.guillon <ben.guil...@gmail.com> wrote: > FYI, dblatex supports callouts on images (see http://dblatex.sourceforge.* > *net/example/dblatex/example.**pdf<http://dblatex.sourceforge.net/example/dblatex/example.pdf>, > section 5.1). > > The only constraint to have relevant coordinates. > > Regards, > BG > > > On Mon, 07 May 2012 16:29:16 +0200, Tyson Marchuk <tmarc...@cdlsystems.com> > wrote: > > Hi Bob, >> >> Thank you.
