If one of the formats you want is SVG, you presumably don't wan't to
generate a raster image as the master output. So why not generate SVG
directly? Using xmerl and the "simple" xml representation, the following
<rect width="300" height="100"
Then export this via xmerl to an XML file "foo.svg",
and if you want a bitmap, run os:cmd("convert foo.svg foo.png")
where 'convert' is the ImageMagick convert command. Just install the
imagemagick package if you don' have it already.
