The following SVG is essentially two circles centered on top of each other. It has radial symmetry. However, when I rasterize this to a 16x16 image, I get something quite obviously lacking radial symmetry. It appears as though things are shifted to the upper left toward (0,0), and smells to me like an integer truncation issue. If I increase the raster dimensions, the problem becomes less pronounced, and ultimately unnoticeable at higher resolutions (e.g. 512x512). I can likely work around this by rasterizing at high resolution and then scaling down to my desired resolution.
This was with Batik 1.7, on with Oracle Java 1.6.0_22 and 1.6.0_29 on Windows 7. For reference, Inkscape will export a raster that appears correct.
