Hello,
I am pretty sure you have to set the path's entire "d" attribute, even if you only want to change one point.
The only way I know how to do this in Batik looks something like this:
//Get the element to modify, there are a number of ways to do this, here is one
SVGDocument svgDoc = svgCanvas.getSVGDocument();
Element myPath = svgDoc.getElementById("myPath");
//Get the attribute to modify String currentD = myPath.getAttributeNS(null, "d");
/* *Provide some code to change the point, store the result in String newD */
//Set the new attribute myPath.setAttributeNS(null, "d", newD);
I am not sure if this is the most efficient way to set an attribute, but it works.
Depending on what you are doing you may have to do this through your canvas' update thread to see the results. For more information on that see http://xml.apache.org/batik/javaScripting.html#Threads
Sorry if this is alot of information you already know, hopefully some of it is helpful.
Good luck, TJ Teegan

Hello,
I am trying to modify path elements, and now, in order to modify a single point I rewrite the whole d attribute for the path. Is there a way to modify only one point in the path without having to rewrite it completely?
Thanks in advance for all your help and attention. Fernando MENDEZ. ENST - PARIS
