SVGOMTextElement

[ananth balasubramanyam <ab...@cs.odu.edu>]

Hi,

I have an SVGDocument created from a SVG file. I am trying to
find all the <text> elements and determine their text length and other
properties. Here is my code and it does not seem to work. Am i doing
something wrong :

NodeList textElements = doc.getElementsByTagName("text");
for (int i=0 ; i < textElements.getLength() ; ++i) {
  SVGOMTextElement textElement = (SVGOMTextElement) textElements.item(i);
  SVGOMRect rect = (SVGOMRect) textElement.getBBox();
  System.out.println(rect.getHeight());
  System.out.println(rect.getWidth());
}

thanks in advance,
Ananth

   use getElementsByTagNameNS("http://www.w3.org/2000/svg", "text");

   Otherwise you are asking for text elements in the 'no name'
namespace.

    I will also mention that you can only get the BBOX if the
associated 'rendering tree' for the elements has been constructed
See: batik.bridge.GVTBuilder.
