Hi

I have managed to crop our svg map that we have using batik but I have noticed that once I open the cropped image within Inkscape it shows any line, rect etc that may interconnect with the viewable area. So I was wondering is there a better way of doing this in batik or is there something Im missing that somebody could point me towards please.

Here is my code sample of the crop function:

private void crop()throws NullPointerException, IOException{
// Create a rectangle at the position and size we wish to crop to
SVGRect rectangle = this.svgDocument.getRootElement().createSVGRect();
rectangle.setX(new Float(this.topXPosition));
rectangle.setY(new Float(this.topYPosition));
rectangle.setWidth(new Float(this.imageWidth));
rectangle.setHeight(new Float(this.imageHeight));

NodeList croppedNodes = this.svgDocument.getRootElement().getIntersectionList(rectangle, null);

Element g = this.newSVGDocument.createElementNS(this.svgNS, "g");

Element rect = this.newSVGDocument.createElementNS(this.svgNS, "rect");
rect.setAttribute("x", "0px");
rect.setAttribute("y", "0px");
rect.setAttribute("width", "" + this.imageWidth);
rect.setAttribute("height", "" + this.imageHeight);
rect.setAttribute("fill", "#FFFFFF");

g.appendChild(rect);

for(int i = 0; i < croppedNodes.getLength(); i++){


Node childNode = (Node)croppedNodes.item(i);

if(childNode.getNodeType() == Node.ELEMENT_NODE){
Element e = this.newSVGDocument.createElement(childNode.getNodeName());

// Process the attributes
if(childNode.hasAttributes()){
this.addAttributes(e, croppedNodes.item(i).getAttributes());
}

// Process the children
if(childNode.hasChildNodes()){
this.addChildNodes(e, childNode.getChildNodes());
}

g.appendChild(e);

this.newSVGDocument.getDocumentElement().appendChild(g);
}
}

try{
FileWriter fstream = new FileWriter(this.newPath);
DOMUtilities.writeDocument(this.newSVGDocument, fstream);
fstream.flush();
fstream.close();
} catch(IOException ioe){

System.out.println("Unable to write to file in crop: " + ioe.getLocalizedMessage());

}
}

Thanks for every ones help so far.

Barry
