Hi Charles,
I'm not sure if this helps you, but I've found bbox to be flakey in some
situations when the element you're using is text. Of course, it might've been
how I was doing things (likely), but if you're not after the bbox per se and
just need some width measurement you could try getComputedTextLength().
Cheers,
Andrew

Hello, all.
I'm wondering if anyone could point me in the right direction re: coaxing an
SVGTextElement to return a correct bounding box when the text contains ISO
encoded characters.
SVGDocument doc = makeSvgDocument(svgString);
SVGTextElement svgTextElement = (SVGTextElement) doc.getElementById("textID");
svgTextElement.getFirstChild().setNodeValue("ΑΩ");
float width = svgTextElement.getBBox().getWidth();
My document is created as follows -
protected SVGDocument makeSvgDocument(String svgString) {
SVGDocument svgDoc = null;
@SuppressWarnings("unused")
GraphicsNode rootGN;
UserAgent userAgent = new UserAgentAdapter();
DocumentLoader loader = new DocumentLoader(userAgent);
BridgeContext ctx = new BridgeContext(userAgent, loader);
GVTBuilder builder = new GVTBuilder();
SAXSVGDocumentFactory factory = new
SAXSVGDocumentFactory(SAXParser.class.getCanonicalName(), true);
try {
svgDoc = (SVGDocument) factory.createDocument("file:///dummy/dummy/file.svg",
new StringReader(svgString));
ctx.setDynamicState(BridgeContext.DYNAMIC);
rootGN = builder.build(ctx, svgDoc);
} catch (IOException e) {
e.printStackTrace();
}
return svgDoc;
}
It appears to me that the result (especially evident for width) is calculated
as if the 1 character is actually 6 characters.
Thank you.
Best regards,
Charles Seelig
