[MapServer-users] setting COLOR of SVG symbol ?

[Seth G]

Hi,

Unfortunately, I don't think this is currently possible, based on a previous reply from Steve Lime [1]:

> I don't believe you can muck with the SVG color since SVG can carry multiple elements and colors. That complexity doesn't map very well to a single color value in a styleObj. It's probably best to consider SVG as immutable, same as an image symbol. You can use truetype fonts (or vector symbols) if you want something scaleable where you can alter color.

I guess if it works in QGIS then it should be possible to implement this in the MapServer codebase too.
