# LaunchSim - Computes center location and zoom level from current view
# and launches tntsim with the appropriate parameters.
# Requires tntsim built March 20, 2002 or later 
# 
# The following symbols are predefined 
#    class VIEW View      {use to access the view the script is run from} 

# Declare variables
class POINT2D center;
class POINT2D left;
class POINT2D right;
class POINT2D point;
class Raster rast;
class Georef ref;

# Get georeference info from .sim file
OpenRaster(rast,_context.ScriptDir+"Otoe_Sim2.sim","TERRAIN");
ref = GetLastUsedGeorefObject(rast);

# Calculate center location in map coordinates
center.x = View.Width / 2;
center.y = View.Height / 2;
center = TransPoint2D(center, ViewGetTransViewToScreen(View, 1));
center = TransPoint2D(center, ViewGetTransMapToView(View, ref.Projection, 1));
 
# Calculate extent of view
extent = View.Width * View.PixelSizeMillimeters * View.CurrentMapScale / 1000;

# Launch simulator
run(sprintf("tntsim.exe POI=%.2f,%.2f DOV=0.0,-30.0 FOV=%.2f \"%sOtoe_Sim2.sim\"",
				center.x, center.y, extent, _context.ScriptDir), 0);
