Raster-Vector Combination

[Riyaz]

Hi,
  I am trying to convert a svg file that has a raster as the background image and other vectors on top of it. I am using batik's transcoder api. Does batik allow this type of conversion? How can I achieve this. Currently  I am getting this run-time error from batik while transcoding:

If I remove the raster(image tag) from the svg file it creates the raster for it. Any tips or hints are greatly appreciated.

Thanks in advance,
