             Summary: org.apache.batik.transcoder.TranscoderException: null
                 Key: BATIK-1122
                 URL: https://issues.apache.org/jira/browse/BATIK-1122
             Project: Batik
          Issue Type: Bug
          Components: SVG Rasterizer
    Affects Versions: 1.6, 1.7
         Environment: Ubuntu 15.04, 64 bit, mostly standard packages
            Reporter: Andreas Schildbach


I have a PNG (see below) that causes this exception when rasterizing. The 
exception is not very helpful and I have no idea why this is. I boiled it down 
to the shadow, if the remove the <feBlend /> line it works, but of course the 
image then doesn't look like I want.
