I need to make a raster from a polyline shapefile. However, when I use gdal_rasterize (either directly or through QGIS), all my lines are drawn one pixel wide, while I need them to be drawn with the stroke weight of 3. I've examined the documentation at http://www.gdal.org/gdal_rasterize.html, but couldn't find a parameter to do so.
I have in mind some workarounds, but is there a simpler way to do so? My workarounds are: - render a raster 9 times smaller and blow it up - write a script that reads the raster and outputs a 3x3 block into another raster whenever it reads a non-zero pixel
