Still I'm left with a "chicken and egg" problem.
All I need to do is to create an SVG document with a piece of text at a specific position and followed by a vertical separation line. Problem is that I need to know the width of the text before I can place the vertical seperation line.
It seems wierd to me, if I'm supposed to first add the separation line at some random position, then fire up the DOM, and then calculate the desired position of the separation line.
- Is there another method of inquiring on the length of a certain string of characters?
- When the sole purpose is to generate an on-disk document, would it be a resonable approach to actually fire up the DOM with an empty document then construct the SVG elements as needed. I assume that in this case it is legal to call getComputedTextLength() immediately after constructing the SVGTextElement.

Hi
According to the SVG conformance page, the following method is supported by Batik:
SVGTextElement.getComputedTextLength()
Yet I have problems with it. I would appreciate if someone could point out for me what I'm doing wrong.
I'm using Batik 1.5.1.
The Code: ----------------------------------------------------------------------
import org.w3c.dom.svg.*; import org.apache.batik.dom.*; import org.apache.batik.dom.svg.*;
public class Test
{
public static void main(String[] args)
{
SVGOMDocument doc = (SVGOMDocument)SVGDOMImplementation.getDOMImplementation().createDocument(SVGDOMImplementation.SVG_NAMESPACE_URI, "svg", null);
SVGTextElement text = (SVGTextElement)doc.createElementNS(SVGDOMImplementation.SVG_NAMESPACE_URI, "text");
text.appendChild(doc.createTextNode("foo"));
System.err.println(text.getComputedTextLength()); } }
----------------------------------------------------------------------
I get this error:
----------------------------------------------------------------------
Exception in thread "main" java.lang.NullPointerException
