[Qgis-user] SVG Fill

Fri Aug 17 06:07:45 PDT 2012

 Hi Jonathan,

 no - QGIS cannot embed SVG files in QML files. And it's not very likely 
 that this will get implemented - unless you pay someone to implement it.

 But the solution with the SVG paths isn't bad/complicated anyway. It is 
 not a lot of work to copy a bunch of SVG files to a central place and 
 set it in the global options, is it?

 Just my opinion,
 Andreas
