[mapserver-users] Symbols for railroad rendering in svg

[TMa Teng]

Thanks for sharing your method.

However that is still brush line for the railway symbol which is not supported when using SVG format, isn’t it? Could you verify if a wms getmap call which contains the railway layer and in the getmap request set the output format=SVG to see if that works at your side?

Thanks again,
Teng

Without seeing the "tie" symbol, its hard to say if mine is different. 
Here's how I draw mine:

SYMBOL
	NAME "railway"
	TYPE truetype
	FONT "Vera"
	CHARACTER "|"
END

CLASS
	NAME 'Railroad'
	STYLE
		SYMBOL 0
		COLOR 0 0 0
		SIZE 1
	END
	STYLE
		SYMBOL 'railway'
		COLOR 0 0 0
		SIZE 7
		GAP -10
	END
END
