Thanks Koen I've read your pdf file you presented in eclipsecon 2006, very helpful to me. I want to record all info (lines,nodes,..) of "processimage.jpg" in another xml file, in order to be monitoring the processses status when it's in running state using SVG. below is a sample : <?xml version="1.0" encoding="UTF-8"?> We currently record this stuff using Picture manupulated program to measure this out. super ineffective. Can u give me some ideas on how to work this out. Does info stored in gbd.xml I can use to caculated this out. Many thanks!! --Michael View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4158568#...
