how can I convert an RGB image to CMYK and vice versa in Java?

Question

our web app let users download dynamically generated images in different formats (bmp, png and jpeg). Some of our users download the images for printing, thus we would like to allow them to choose between RGB or CMYK. Is there a way to specify the color model when creating a RenderedImage/BufferedImage? If not, what is the default color model and how can I change it to another? Code snippets are welcome :)

Thanks,

Olivier.

It appears that it's not simple and you'll have to either load up a color profile to do it or extend the colorspace to support CYMK.
