Description

We have a process to generate SVG charts using XChart, which are then embedded in an HTML document and rendered as PDFs using Flying Saucer. Batik is plugged into the pipeline to render the SVGs.

We've found that the bar charts created by XChart are not properly rasterized by Batik, even though they can be rendered within Chrome, Firefox, Inkscape, and other SVG-capable software. I was able to duplicate the issue using the standalone Batik Rasterizer program.

The attached svg.zip file contains a sampling of SVGs generated with XChart. The png.zip file contains the results of running java -jar batik-rasterizer-1.17.jar -d ./*.svg. You can see that all of the bar charts are rendered as empty (transparent?) 700x750 PNGs, whereas the line & pie charts are rendered correctly. This seems to be a bug, though it's possible that the SVGs in question use a feature that is not currently supported by Batik.
