[mapserver-dev] Question on SVG symbol sizes

[Stephen Woodbridge]

Hi SVG devs,

I have a question on SVG symbols in mapserver and how do you change the 
size of the rendered symbol.

For example I have an SVG symbol for a US hwy shield that was built 
600x600 pixels.

I want it to render 20x20 pixels in my map image output. I have a LAYER 
definition like the following. I just added a patch to #4247 to get this 
to render at all, but the symbol is rendered very large.

Since this is a lot of new code all getting dumped into trunk, I don't 
know if I am looking at a bug or user error or what?

Any thoughts on this?

Thanks,
