Hi Tilo,
can you explain what you mean by 'painted the wrong way round'?
Another thing that might interest you is that after I create the svg element
from the shape I set the viewbox on the clipped document so that the clipped
region gets fully display in a SVGCanvas.
Rectangle2D rect = shape.getBounds2D();
int offx = 10;
int offy = 10;
float offsetx = rect.getWidth() / 100 * offx;
float offsety = rect.getHeight() / 100 * offy;
String viewBoxAttr = (rect.getX() - (offsetx / 2)) + " " +
(rect.getY() - (offsety / 2))
+ " " + (rect.getWidth() + offsetx) + " " +
(rect.getHeight() + offsety);
doc.getRootElement().setAttributeNS(null,
SVGConstants.SVG_VIEW_BOX_ATTRIBUTE,
viewBoxAttr);

Hi Tilo,
I have the same problem (big svg map file) and I couldn't come up with any
solution either.
I guess you could probably cut off the non visible parts by hand out of the
document but I haven't any clue if there is a nice solution to that problem.
Perhaps Andreas had a similar issue?

Betreff: AW: Clipping SVG documents
Hi Dominik,
i have found my failure. My next Question is it is possible to generate a
SVG Document that only contains the svg code from the clipping path. The
main Problem is i have tree JSVGCanvas in the first i show the hole map in
the second a part of this map (like a district) and in the last i show only
a special point of the map. The problem is when i have a svg File that is
1Mb big the batik needs 600 Mb Memory and the system works very slow. Have
anybody a idea to solve this problem.

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
