I am scanning a SVG file (polo_text.svg attached to this mail) with the following Java
code. I am trying to get the bbox size of a text element and I receive an exception on
the getWidth() call.
Any help would be kind, thank you,
Charles.
---------------------------------------------------------------
Java code:
while (node != null) {
if (node instanceof SVGLocatable){
System.out.println("node name = " + node.getNodeName());
SVGLocatable svgLoc = (SVGLocatable)node;
System.out.println("SVGLocatable = " + svgLoc);
SVGRect rect = svgLoc.getBBox();
System.out.println("BBox = " + rect);
float width = rect.getWidth(); <-- Exception raised here
}
}
---------------------------------------------------------------
Output:
node name = g
SVGLocatable = org.apache.batik.dom.svg.SVGOMGElement@d6747b
BBox = org.apache.batik.dom.svg.SVGLocatableSupport$1@2e7c6a
