Hi Tilo,
perhaps this one can help:
// shape is your clipping shape, so for example a polygon and
// svgDocument the document you want to clip
public void clipMap(SVGDocument svgDocument, java.awt.Shape shape)
{
// first clone the document
SVGDocument doc = (SVGDocument) svgDocument.cloneNode(true);
// create an svg element from the clipping shape with the cloned
document
SVGGraphics2D svgGenerator = new SVGGraphics2D(doc);
Element svgShape = svgGenerator.getShapeConverter().toSVG(shape);
// add the clipping element to the <defs> tag of the document
NodeList n1 = doc.getRootElement().getElementsByTagName(
SVGConstants.SVG_DEFS_TAG);
Element defs = (Element) n1.item(0);
// create the <clip-path> tag
Element clip = doc.createElementNS(svgNS,
SVGConstants.SVG_CLIP_PATH_TAG);
clip.setAttributeNS(null, SVGConstants.SVG_ID_ATTRIBUTE, "clipmap");
// append the clip shape to the clip path and the <defs> tag
clip.appendChild(svgShape);
defs.appendChild(clip);
// reference the clipping from the element you want to clip
Element el = doc.getElementById("myelement");
el.setAttributeNS(null, SVGConstants.SVG_CLIP_PATH_ATTRIBUTE,
"url(#clipmap)");
}

Betreff: Clipping SVG documents
Hi all,
I have an SVG document and I want to generate an SVG document that contains
only a smaller part of this document - just cut a rectangle from the
original image. Does anyone have an idea about how to do this using the
Batik toolkit ?
MfG
Tilo
