[mapserver-dev] Question on SVG symbol sizes

[thomas bonfort]

Steve,
I haven't experimented with svg symbols extensively. I did add some
autotests that use scaling and rotating, and it would seem to work:

http://trac.osgeo.org/mapserver/browser/trunk/msautotest/renderers/point_svg.map
http://trac.osgeo.org/mapserver/browser/trunk/msautotest/renderers/expected/point_svg.png.png

ps: looking at the link you sent, the symbols seem correct to me. is
this still an issue ?
