[mapserver-users] Symbols for railroad rendering in svg

[TMa Teng]

Thanks Andy,

My 'tie' symbol is same as your 'railway', the actual problem is the track...

My original one is as follow:
	SYMBOL
	  NAME "line_solid"
	  TYPE ellipse
	  POINTS 1 1
	  END
	  FILLED true
	END

I changed it to what you suggested, and it works perfectly for SVG output.

Really appreciate your help.

Best regards,
Teng

Oh, also, my mapserver is:

MapServer version 7.0.2 OUTPUT=PNG OUTPUT=JPEG SUPPORTS=PROJ SUPPORTS=AGG SUPPORTS=FREETYPE SUPPORTS=CAIRO SUPPORTS=ICONV SUPPORTS=WMS_SERVER SUPPORTS=WFS_SERVER SUPPORTS=WCS_SERVER SUPPORTS=FASTCGI SUPPORTS=GEOS INPUT=JPEG INPUT=POSTGIS INPUT=OGR INPUT=GDAL INPUT=SHAPEFILE
