should render a blue circle. canvg renders a blue ellipse.

Let's discuss since I believe that I implemented viewBox correctly per the spec
( http://www.w3.org/TR/SVG/coords.html#ViewBoxAttribute ). svg has a "width" and
"height" property which determine the canvas size. if not provided, you can fake them
on the test page (1000,600 by default) using the boxes. if in this example you set the
width/height property to 400,400 then you will get a circle. otherwise it does the
"stretch to fit" described in the spec. so either type width="600" height="600" into
the svg element or put 600,600 into the text boxes and you should see a circle.

p.s. cool android.svg :)

ah, I believe you are right, this is really about preserveAspectRatio, see http://www.w3.org/TR/SVG/coords.html#PreserveAspectRatioAttribute since the default
value for preserveAspectRatio is midXMidY.

Take a look at the image in any browser (other than IE9)

Summary: preserveAspectRatio is not supported

got it, thanks for the clarification! will add matrix transforms first (might refactor
that whole section) then look at this eventually so grab it if you want (set status to
started if you do).

I'm made some decent progress on this yesterday night and today during lunch. I have
to support nested svg's and changing view ports which is taking a while but I'm close
to have the smiley face example working. Should be checked in tonight.

if you see any regressions!

Status: Fixed
