Convert SVG to PDF in python

I am trying to convert an SVG file to PDF in python using the svglib and reportlab packages. Here is the SVG file. Here is the code I am using to convert (got this from svglib webpage). >>> from svglib.svglib import svg2rlg >>> from reportlab.graphics import renderPDF >>> drawing = svg2rlg("file.svg") >>> renderPDF.drawToFile(drawing, "file.pdf") The code runs fine without any error or exception but the file.pdf thus generated is a blank file. I mean that when I open this PDF file I see nothing but only white background page with nothing on it. Where am I going wrong ?
