The MarkersSymbolizer should draw blue directional arrows *in the direction of the geometry* (for things like one-way streets).
The [[MarkersSymbolizer]] should draw blue directional arrows *in the direction of the geometry* (for things like one-way streets).
In case you notice arrows pointing the wrong direction, this means that the segment has been coded in the wrong way.
The ST_reverse function of Postgis can fix this (The problem will then be to identify the geometries that need to be updated).
### SVG markers
*NEW*: Staring from r1793 MarkersSymbolizer supports [Scalable Vector Graphics (SVG)](http://www.w3.org/TR/SVG/) as input images:
