matplotlib-devel Mailing List for matplotlib (Page 2)

I'd be curious to see a screenshot of what Safari looks like.  It may be a simple fix on our end.

As for file sizes, the SVG spec makes an "informational recommendation" to allow gzip-compressed SVG files.  So some tools support commpression (Inkscape), and others don't (Firefox).  Hopefully more will start supporting that.

As of yesterday, you can save a gzipped SVG file directly from matplotlib by specifying "svgz" as an extension.

Cheers,
Mike

I'm not sure about the cairo backend in matplotlib. But cairo itself
definitely has very good for polygon, (and curve-based path),
clipping. So it should be extremely trivial to add that to the cairo
backend in matplotlib if it's not there already.

And I'd be glad to help anyone doing this if they got stuck.

Is there a URL that describes this in much detail -- a little searching 
turns up the odd tidbit, but nothing I can sink my teeth into. I'm 
interested because my understanding is that different OpenGL 
implementations draw things (slightly) differently, so I'd be curious 
how they deal with that...

A minor correction -- all the backends support rectangular clipping --
but only agg supports polygon clipping currently.  The polar axes uses
a polygon approximation to a circle for the axes border which is used
to clip the lines.  I think this would be fairly easy to add to ps,
pdf, and svg since i think they all have support for polygon clipping.
 I'm not sure what the cairo status is.
