  * SVG to raster conversion example using ImageMagick

+ * Please note that conversion via ImageMagick may not always produce ideal results,
+ * especially when using CSS styling (external or via <defs>), also it depends on OS and Imagick version.
+ *
+ * Using the Inkscape command line may be the better option:
