can I place Overlapping images in fo

Hi ,
I would like to place one image (jpeg-CMYK) over a another like a pack of
cards spread. Or do we have anything like the layers of Netscape in fo.

Using SVG like this 	<image xlink:href="image_cmyk.jpg" x="0.1in" y="0.1in"
width="1.1in" height="1.1in"/>  gives
sun.awt.image.ImageFormatException: Unsupported color conversion request
        at sun.awt.image.JPEGImageDecoder.readImage(Native Method)
        at sun.awt.image.JPEGImageDecoder.produceImage(Unknown Source)
        at sun.awt.image.InputStreamImageSource.doFetch(Unknown Source)
        at sun.awt.image.ImageFetcher.fetchloop(Unknown Source)
        at sun.awt.image.ImageFetcher.run(Unknown Source)

S i need a way to make layers using
<fo:external-graphic src="image_cmyk.jpg" width="0.37in" height="0.37in"/>

Thanks In advance.

Regards/Naveen

There is z-index in XSL-FO, but this is not implemented in FOP. You can 
set the background image for a region and overlay an image on top. But I 
dont think you can achieve what you want using FOP 0.20.5.

If the SVG fails then you need to ask why it doesnt work on the Batik 
list. I suspect it has something to do with CMYK images. If you can 
solve this issue, then SVG may be the best approach to get what you want.
