Thanks for finding this. Fixed in r8917/r8918.

It's not obvious to me that this is wrong. The path has a MOVETO 
command (1) in the middle, and thus should require the creation of two 
polygons. Can you provide some code or pictures that demonstrate the 
problem?

Hello,
I run the test.py example from the folder mplh5canvas/test. This example
generated in the output folder 2 html pages (test.html and
test_rendered.html) and also 2 images (filename.png and filename.svg). The
test.html page is displayed ok, but when I open the test_rendered.html page
the images from the column "H5 Canvas (PNG from Chrome 4.0 OSX)" are not
displayed.
After I studied the source code of the test.py example I saw the following
line:
(line 85) thtml += "<td><img src='%s' width='%dpx' height='%dpx' />" %
("h5canvas_" + png_filename, w, h)
Now the question is: What is supposed to be "h5canvas_" + png_filename?
There is no image generated with this name in the output folder.
The HTML 5 Canvas Backend was downloaded from here:
http://code.google.com/p/mplh5canvas/downloads/list
Thanks!
