Note on image file formats

This module generates SVG file which is an XML-based vector image format. You can use various libraries and/or utilities to convert it to other vector or bitmap image formats. Below is an example how to use libRSVG to convert SVG images.

libRSVG

libRSVG renders SVG files using cairo and supports many output image formats. It can also be used directly in console with rsvg-convert command.
