Adding raster images

[maria teresa <ma...@isti.cnr.it>]

Hi,
I am developing a Java application that has to meet the following requirements:
1) load and display an SVG image on a JSVGCanvas;
2) when mouse is double clicked, a small jpg image should appear on the 
canvas at
the coordinates  where double click occurs;
3) the SVG file should be modified in order to embed that image in the same 
position.

  Actually, I have no idea about how to achieve requirement 3).

I am quite new to Batik, and  I don't know its API very well,
especially the classes/interfaces that deal with the DOM.
Any suggestion would be really appreciated!!

Thank you,
mt

hi,

you could do something like this:
- since JSVGCanvas is a JComponent, you can add mouse listener
- on the mouse click event
SVDocument doc = canvas.getSVGDocument();
// create the image
SVGImageElement imgElt = (SVGImageElement)doc.createElement("img");
// set the image attribute
imgElt.setAttributeNS(xlinkNs,etc,etc);
imgElement.setAttributeNS(null,xAttr,xCoord);
imgElement.setAttributeNS(null,yAttr,yCoord);
...
// put the image element into svg doc
SVGSVGElement svgElt = doc.getSVGElement();
svgElt.append(imgElt);
// refresh the canvas. sorry forget the syntax :)

The difficult part is matching the screen coordinate with the transform
& viewbox of the svgDoc, including the current zoom stage
