[Qgis-user] inserting symbols into qgis

[sunny74]

Hi Andreas,

Thanks for your reply.

* I am putting the files in the correct installation of QGIS so that is not
a problem.
* The cause that the SVG is an invalid SVG seems to be the problem. The SVG
does not open
   in any of the browsers. Worst is that it is produced by Inkscape. Is
there any other tool which will produce a valid .svg.

* permissions seem to be ok.

Pls suggest a couple of other tools for converting raster to .svg.

Regards.
