/**
* 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:
