[gdal-dev] Correct sintax for multicommand in FeatureStyle specification

[Even Rouault]

Andrea,

Both work for me.

Tested with :

* foo.csv :

id,WKT,OGR_STYLE
1,"POLYGON((1 1,1 9,4 9,4 1,1 1))","LABEL(f:""Arial"",t:""Blah Blah Blah"",s:3g,c:#0000FF);BRUSH(fc:#FF0000)"
2,"POLYGON((5 1,5 9,9 9,9 1,5 1))","BRUSH(fc:#FF0000);LABEL(f:""Arial"",t:""Blah Blah Blah"",s:3g,c:#0000FF)"

(the repeated "" is due to CSV escaping of double quotes)

* foo.map :

MAP
    NAME test
    EXTENT 0 0 10 10
    SIZE    200 200

    PROJECTION
        "init=epsg:4326"
    END

    WEB
        METADATA
            OWS_ONLINERESOURCE "http://127.0.0.0.1"
            OWS_SRS "EPSG:4326"
            OWS_ENABLE_REQUEST "*"
        END
    END

    LAYER
        NAME foo
        TYPE POLYGON
        STATUS ON
        CONNECTIONTYPE OGR
        CONNECTION "foo.csv"

        STYLEITEM "AUTO"
        CLASS
        END
    END
END

* test command :

shp2img -m foo.map -o foo.png

Attached the resulting foo.png

Best egards,

Evn
