Hi all:
I'm having a problem getting an SVG image to work as a PointSymbolizer
when running cascadenik-compile.py.
Here's the CSS I'm using:
.alluncertified
{
point-file:
url('/Users/semchie/Documents/CIR/seismic/mapnik/uncertified/testpoint8.svg');
point-width : 8 ;
point-height : 8 ;
point-allow-overlap : true ;
}
This works fine if I switch to a .png image, but when I run
cascadenik-compile.py with the .svg I get the following error:
raceback (most recent call last):

IOError: cannot identify image file
Is this likely a more general problem with .SVGs in cascadenik, or am I
perhaps having problems because of the way I exported the .SVG? I used
Adobe Illustrator with these settings:
SVG profiles: SVG 1.1
Type: SVG
Images
Location: Embed
This produces this for the SVG body:
<?xml version="1.0" encoding="utf-8"?>
<!-- Generator: Adobe Illustrator 14.0.0, SVG Export Plug-In . SVG
Version: 6.00 Build 43363) -->
<!DOCTYPE svg PUBLIC "-//W3C//DTD SVG 1.1//EN"
"http://www.w3.org/Graphics/SVG/1.1/DTD/svg11.dtd";>
<svg version="1.1" id="Layer_1" xmlns="http://www.w3.org/2000/svg";
xmlns:xlink="http://www.w3.org/1999/xlink"; x="0px" y="0px"
width="800px" height="600px" viewBox="0 0 800 600"
enable-background="new 0 0 800 600" xml:space="preserve">
<circle fill="#C1272D" stroke="#000000" cx="295.643" cy="155.5" r="20.357"/>
</svg>
Thanks much!
