[Qgis-user] SVG symbols and conversion to PDF

[Andreas Neumann]

 Hi all,

 I'd like to share something I discovered recently, partially with a 
 hint from Marco, when converting SVG symbols to PDF.

 1. SVG symbols in the old symbology are rasterized (that one I knew), 
 but in the new symbology they stay as vectors (that one I didn't know).
 2. There is a major bug in the SVG->PDF conversion of SVG point symbols 
 in the new symbology, due to a bug in the underlying qt-classes: 
 path-elements or other other basic geometries are always stroked in the 
 output PDF, unless one explicitly assigns a stroke-width="0"

 This violates the SVG standard in two ways:
 1. objects aren't stroked in SVG unless explicityl specified with the 
 stroke and stroke-width attributes
 2. if one specifies stroke="none" in SVG qt's SVG->PDF converter still 
 strokes the elements until one explictly sets the stroke-width to zero.

 This is really annoying as it means I have to go over all of my SVG 
 symbols and add the stroke-width="0" for objects I only want to fill and 
 not stroke.

 I just wanted to let you know in case you run into similar issues.

 Andreas
