SVG support

[ananthrk]

I am using the play-pdf module with play-1.2.3 to generate PDF from template html files. My approach is to send the html source (using document.documentElement.innerHTML) to the server and temporarily storing the html source to a ".html" file and use renderPDF function to generate the PDF. This works fine for normal pages. However, if my pages contain charts (either Google charts or jqplot), then I get the following exception:

Oops: CConvertException

Is this due to the charts being SVG? If yes, how can I make play-pdf handle SVG content? If not, what could be source of this error? Thanks.
