Embed a png in svg using Batik
I'm completely new to Batik. I need to know how to refer to an png file
through an svg file using Batik.
Please help me on this case.

I think my problem is solved. I can use
import org.apache.batik.dom.svg.SVGDOMImplementation;
import org.w3c.dom.DOMImplementation;
and manage my program.
Thank You.

So you are drawing the diagram using Java
Graphics2D and displaying that in the Canvas?
You can always use Java2D to fetch an decode the PNG image
using java.awt.Toolkit.createImage(URL) (make sure the image
is fully loaded before you draw it to the SVGGraphics2D).

Alternately if you are already manipulating the SVG
document after SVGGraphics2D has generated most of it you
can use Document.createElementNS to create an SVG image element
and the Element.setAttributeNS to set the xlink:href attribute
(to either a URL for the PNG, or base64 data - which you
can get from the Batik.util.Base64EncoderStream). I suspect
just drawing the Image to the Graphics2D will be your
best bet.

Thank you again you support.
I use
import org.apache.batik.dom.svg.SVGDOMImplementation;import
org.apache.batik.svggen.SVGGraphics2D;
import org.apache.batik.swing.JSVGCanvas;
import org.w3c.dom.DOMImplementation;
import org.w3c.dom.Element;
import org.w3c.dom.svg.SVGDocument;
above set of classes for my program. I have some data from a DB and based on
those data I need to generate a flow diagram using SVG.
For some components in that flow diagram I need to display png images.

Batik is a large package without knowing how or what you
are using from Batik I don't know what you mean by using Batik
to specify the parameters.
Can you give a little more background on what you are doing
and how you are using Batik?

or you could remove the base64 aspect of it and use
xlink:href="file:///mypath/myfile.png"
