Does the App Engine Conversion API for HTML to PDF support canvas or SVG?
You could export the canvas to an image (toDataURL) after the user creates or modifies the chart, and swap the two when calling the Conversion API.
I am trying to figure out the best way of allowing my users to create a family tree chart, view it on screen and then to be able to create a PDF of it.
I am considering using ReportLab for the PDF generation, however then I have to have separate display and PDF code.
So I was wondering if the Conversion API would be able to handle HTML with canvas (and therefore Javascript), I am guessing probably not, but I thought I would ask.
I am a little more hopeful about it being able to generate HTML with SVG since it can be rendered without javascript.
