This attribute enables you to place elements anywhere within a document, not just as descendants of form elements.

While this does output the raw RGBA version of the image that's good enough for what I needed to do. Yes the original answer was also valid but it involved first converting the image to a BufferedImage and I ideally wanted to avoid swing entirely.
