MapScript SetSymbolSet

[Sean Gillies]

Oh, I see. Yeah, it's possible. Here's an example from one of my  
Python projects:

     circle = mapscript.symbolObj('circle')
     circle.type = mapscript.MS_SYMBOL_ELLIPSE
     circle.filled = mapscript.MS_TRUE
     line = mapscript.lineObj()
     line.add(mapscript.pointObj(1,1))
     circle.setPoints(line)
     circle.sizex = 1
     circle.sizey = 1
     mo.symbolset.appendSymbol(circle)

The "mo" name is bound to a mapObj. It's very important to get sizex  
and sizey right, should be the width and height of the symbol in the  
same units as the point and line coordinates used to construct the  
symbol.

To use this symbol

     style.symbol = mo.symbolset.index('circle')

Translate this into C# and you should be good to go.

cheers,
Sean
