@Justin I looked into using Imagemagick, but I cannot seem to find if it supports converting/exporting from svg by object ID, which is needed. Do you know anything about that?
I know Imagemagick supports rsvg and rsvg-convert has export by ID (--export-id) as an option, but the rsvg-convert command returns "command not found." Another issue discussed on the forums said that lbrsvg 2.40 doesn't include rsvg-convert, but we are on 2.45 now so it should work I thought. Any ideas?
