Hi,
i just implement a java tool to generating an image map from a svg.
At first i get my map.svg file over an InputStream and parst it to an
Document.
String parser = XMLResourceDescriptor.getXMLParserClassName();
SAXSVGDocumentFactory f = new SAXSVGDocumentFactory(parser);
Document doc = f.createDocument(null, input);
With this document I get the dom element by id and the attribute "d" as
a String.
For example:

Now i parse this string with a PathParser and PathHandler. This works
nice and i get an output like this:
movetoRel: 479.231, 243.809
linetoRel: 0.545, 0.476
linetoRel: 1.067, 0.581
linetoRel: 0.587, -0.18
linetoRel: 0.434, -1.184
linetoRel: 0.607, -1.417
linetoRel: 0.581, -0.793
linetoRel: 0.8, -0.613
.....
The problem, which I have is, that i need absolute coordinates for the
image map and i don't know how to convert
these relative coordinates to absolute.
Maybe someone have a solution for me :)
Thanks for help ;)
