Thanks Thomas. That was the crucial step I was missing, it works
nicely now. Thanks Cameron and Tonny for the property computation help.

Hi James,
Ahh, you need to boot the CSS DOM:

Thanks for the suggestion. Unfortunately I get identical results
using this method, a null pointer exception on the
getPropertyCSSValue
(). Is there something else I need to do to calculate the stroke?
Perhaps I am missing something in the setup. I am creating the
document from a file stream using the following snippet I found in
the docs somewhere:
String parser =
XMLResourceDescriptor.getXMLParserClassName();
SAXSVGDocumentFactory f = new SAXSVGDocumentFactory
(parser);
SVGDocument doc = (SVGDocument)f.createDocument
("http:internal", is);
After that I use getElementsByTagName() to find the paths, which I am
then using as the element in your example code. Does anything look
out of place?
Thanks, James.

When I try this, the CSSStyleDeclaration ends up containing an
"element" member of type SVGOMPathElement that has attributes
"fill"
and "d", but the CSSStyleDeclaration "values" member HashMap is
empty.
When I call style.getPropertyCSSValue("stroke") I get a null

exception, even though this value exists up in the main svg
element.
How about something like this
ViewCSS viewCSS =
(ViewCSS)element.getOwnerDocument().getDocumentElement();
CSSStyleDeclaration computedStyle =
viewCSS.getComputedStyle(element,null);
SVGPaint svgPaint =
(SVGPaint)computedStyle.getPropertyCSSValue
(SVGConstants.SVG_STROKE_ATTRIBUTE);
Color color = null;

RGBColor rgbColor = svgPaint.getRGBColor();
CSSPrimitiveValue redValue = rgbColor.getRed();
CSSPrimitiveValue blueValue = rgbColor.getBlue();
CSSPrimitiveValue greenValue = rgbColor.getGreen();
float r = redValue.getFloatValue
(CSSPrimitiveValue.CSS_NUMBER);
float g =
greenValue.getFloatValue(CSSPrimitiveValue.CSS_NUMBER);
float b = blueValue.getFloatValue
(CSSPrimitiveValue.CSS_NUMBER);
color = new
Color((int)r,(int)g,(int)b);
} else if (svgPaint.getPaintType() ==
SVGPaint.SVG_PAINTTYPE_CURRENTCOLOR) {
// this is the color keyword eg: black, blue, green,
aliceblue,etc
// please check with the SVG / CSS Dom for the exact RGB value
for
this
color keyword
} else if (svgPaint.getPaintType() ==
SVGPaint....) {
