CSharp-Mapscript: setSymbolSet doesn't work?!

Hi,
thanks for your quick response Tamas, but the symbols don't work up to now.
Normaly it should work with the gif-File in the parameterlist too, the gif-File exists on my System. But I tested it with your code for the symbolObj a lot of times, because that seems to be more simple. Directly before and after calling mapObj.draw() I saved the mapfile build by my Application. I tested both mapfiles in my Browser and both of them are working correct. I will insert the two mapfiles in this email.
Here is my original code I use with some expressions:
public class Controller
{
//myMapHandler is a type of the class MapHandler which handels Objects of the class Map. Map is a Subclass of mapObj
private MapHandler myMapHandler = new MapHandler();
public void InitializeLayers()
{
//PipelineLayer is a Subclass from layerObj
//The first parameter in the Constructor is the mapObj, the second one the status of the Layer, the third one is the Connectionstring to my WFS-Server
//I've got good reasons for giving null in the parameterlist for the mapObj and using the InsertLayer-Method later.
//I tested it with giving directly the mapObj in the constructor, it also doesn't work
PipelineLayer trajektorie = new PipelineLayer(null, true, "http://localhost/cgi-bin/mapserv.exe?");
//Building the Symbol:
symbolObj symbol = new symbolObj("mySymbol", null);
symbol.type = (int)MS_SYMBOL_TYPE.MS_SYMBOL_VECTOR;
symbol.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));
symbol.setPoints(line);
´ myMapHandler.Map.SymbolSet.appendSymbol(symbol);
classObj classtest = new classObj(trajektorie);
classtest.name = "test";
styleObj myStyle = new styleObj(classtest);
myStyle.symbolname = "mySymbol";
myStyle.size = 150;
myStyle.color = new colorObj(255, 0, 0, -1);
myMapHandler.Map.SymbolSet.save(Environment.CurrentDirectory + @"\test.sym");
myMapHandler.Map.InsertLayer(trajektorie, -1);
// the Method Refresh Map is displayed above
myMapHandler.Map.RefreshMap();
}
}
public class Map : mapObj
{
:
:
public void RefreshMap()
{
Cursor.Current = Cursors.WaitCursor;
try
{
lock (this)
{
this.Save(Environment.CurrentDirectory + @"\testBefore.map");
using (imageObj image = this.draw())
{
this.Save(Environment.CurrentDirectory + @"\testAfter.map");
byte[] img = image.getBytes();
using (MemoryStream ms = new MemoryStream(img))
{
myImageHandler.ImageMap = Image.FromStream(ms);
}
}
}
}
catch (Exception ex)
{
MessageBox.Show(ex.Message + "\n" + (ex.InnerException != null ? ex.InnerException.Message : "")
, "Error", MessageBoxButtons.OK, MessageBoxIcon.Error);
}
finally
{
Cursor.Current = Cursors.Default;
}
}
:
:
}
I've got no idea where else I have to search the mistake, or is it even possible that there is a another Bug in the mapscript who is responsible for that?
Best Regards
Christian
