Thanks, Thierry. I appreciate your time & help. However, I am still not getting it to work.
I created simple little test program to illustrate my problem. The test program has 2 parts; the first part reads an SVG file from disk(I enclosed the one (test.svg) that I used for testing) & transcodes(this works). The second part uses a method in the class to create a very simple SVG Document & transcodes it(this doesn't work). When you run the code, you will notice that no errors are thrown. However the first part creates a valid jpg whereas the second produces a blank image. So from this I have 2 questions: 1) Why isn't the SVG Document able to be transcoded properly & 2) why isn't the transcoder throwing an exception on the SVG Document?

The following page on our website shows how to use the ImageTranscoder with a Document. http://xml.apache.org/batik/rasterizerTutorial.html --- Things to care about: a. Your Document must have been created using our DOMImplementation (see the documentation on the website). This is due to the fact that we need some special features that are *not* part of the standard DOM api. So the xerces (or others) DOM implementation can *not* be used. If you can not bootstrap your DOM using our DOMImplementation, you can use the DocumentWrapper class (package org.apache.batik.dom) that will wrap your SVG DOM subtree into another identical DOM subtree using our DOMImplementation (xerces -> batik DOM for example). Then, the resulting tree can be sent to the transcoder. b. if your document uses external references (such as external use, image...), you must specify the URL of your document (ie. that will be used to find and load thoses external resources). You can do that using the ((SVGOMDocument)doc).setURLObject(url) Hpoe that helps, Thierry.
