public void DrawPolyline(ESRI.ArcGIS.Carto.IActiveView activeView)
{
if(activeView == null) return;
ESRI.ArcGIS.Display.IScreenDisplay screenDisplay = activeView.ScreenDisplay;
screenDisplay.StartDrawing(screenDisplay.hDC, (System.Int16)ESRI.ArcGIS.Display.esriScreenCache.esriNoScreenCache); // Explicit Cast
ESRI.ArcGIS.Display.IRgbColor rgbColor = new ESRI.ArcGIS.Display.RgbColorClass();
rgbColor.Red = 255;
ESRI.ArcGIS.Display.IColor color = rgbColor; // Implicit Cast
ESRI.ArcGIS.Display.ISimpleLineSymbol simpleLineSymbol = new ESRI.ArcGIS.Display.SimpleLineSymbolClass();
simpleLineSymbol.Color = color;
ESRI.ArcGIS.Display.ISymbol symbol = (ESRI.ArcGIS.Display.ISymbol)simpleLineSymbol; // Explicit Cast
ESRI.ArcGIS.Display.IRubberBand rubberBand = new ESRI.ArcGIS.Display.RubberLineClass();
ESRI.ArcGIS.Geometry.IGeometry geometry = rubberBand.TrackNew(screenDisplay, symbol);
screenDisplay.SetSymbol(symbol);
screenDisplay.DrawPolyline(geometry); //I WANT TO CREATE THIS FROM LAT / LONGs!
screenDisplay.FinishDrawing();
}
The above code snippet works but the problem is I want to create the IGeometry from lat \ longs not from clicking the screen. How can I create an polyline IGeometry object for the drawPolyline function using standard lat \ long coordinates?
