I found that setting the rasterizer "-indexed" parameter to 1 effectively turns off anti-aliasing as it forces there to be only 2^1=2 colors in the result PNG image:
java -jar batik-rasterizer.jar -indexed 1 The indexed parameter is not listed on the rasterizer web docs: http://xml.apache.org/batik/svgrasterizer.html#using But it is listed when running the rasterizer at the command line: "-indexed (1|2|4|8) Reduces the image to given number of bits per pixel using an adaptive pallete, resulting in an Indexed image. This is currently only supported for PNG conversion."
