Re: [mapserver-users] Symbols for railroad rendering in svg

Seems to work fine:

http://maps.camavision.com/map/jasperia?LAYERS=railroad&TRANSPARENT=TRUE&SERVICE=WMS&VERSION=1.1.1&REQUEST=GetMap&STYLES=&FORMAT=svg&SRS=EPSG%3A3857&BBOX=-10383282.7081,5105096.2257452,-10333332.7081,5127296.2257452&WIDTH=1998&HEIGHT=888

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

Hi all,

I am working on a project to export the wms to SVG format, it is the from the 
requirement of the features to be in vector format. And I am facing trouble to 
use the render engine to render the railroad symbol as a brush line.

RailRoad Symbol I am using is as follow:

        CLASS
                NAME "MD_Railroad"

                STYLE
                   SYMBOL "line_solid"
                   SIZE 2
                   COLOR 0 0 0
                END
                STYLE
                   SYMBOL "tie"
                   SIZE 6
                   COLOR 0 0 0
                   GAP -10
                END
        END

It works as expect when the return image in raster format such as PNG, but when 
using SVG it shows error:

"msDrawLineSymbol(): Renderer error. renderer does not support brushed lines"

Does anyone have any suggestion about how to design a vector-enabled symbol for 
railways please? I am using MapServer 7.0, data is in SQL Server Spatial.

Best regards,

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
