FYI,
The following works fine:
java -jar batik-rasterizer.jar -m image/jpeg -a 0,0,250,250 -d . anne.svg
When I use the sample programs on the Batik website (SaveAsJPEG or
SaveAsJPEGTiles), I get an exception when using the exact same SVG
document. The API program complains about the Batik Logo for some
reason.
The anne.svg (actually most of our samples) contains a
relative reference to the Batik Logo which provides a box and
the Batik 'squiggle' in the lower right hand corner. When you
copied anne.svg to to /tmp/flow/custom you didn't copy
the Batik Logo so the relative reference failed.
