You need to create a new svg file and save it with the same name. You can use batik.dom.util.DOMUtilities.writeDocument to do this (some people appear to have problems with this, but I don't know why) you can also use the Java XSLT engine to write the document but I'm not familiar with that. > > Thanks in advance > > > thomas.deweese wrote: > > > > Hi Vyang, > > > > vyang <[EMAIL PROTECTED]> wrote on 01/15/2007 10:45:16 AM: > > > >> I also do use getIntersectionList() and it does return the correct > > elements, > >> however, how do I get the element point that is near where I clicked? > > > > One needs to be clear what part of element you are interested in.
