CSharp-Mapscript: setSymbolSet doesn't work?!

[Tamas Szekeres]

Hi,

Constructing symbolObj you are using:

"symbolObj(string symbolname, string imagefile)"

The second parameter - if exists - point to an image for rendering that symbol.
In your case the followings should work:

symbolObj mySymbol = new symbolObj("mySymbol", null);
mySymbol.type = (int)MS_SYMBOL_TYPE.MS_SYMBOL_VECTOR;
mySymbol.filled = mapscript.MS_TRUE;
lineObj line = new lineObj();
line.add(new pointObj(1, 5, 0, 0));
line.add(new pointObj(1, 3, 0, 0));
line.add(new pointObj(3, 2, 0, 0));
line.add(new pointObj(1, 1, 0, 0));
line.add(new pointObj(1, 3, 0, 0));
mySymbol.setPoints(line);
myMap.symbolset.appendSymbol(mySymbol);

I haven't tested it so additional properties might be set, apologies.

Tamas
