Subject RE: Modifying path elements.
Date Tue, 07 Dec 2004 18:37:18 GMT

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 
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 

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 

Sorry if this is alot of information you already know, hopefully some of it 
is helpful.

Good luck,
TJ Teegan
