Hi,
Recently I’d migrated to MapSuiteWPFDesktop Ver 10. The migration process was went well except for EcwRasterLayer. Previously in ver 9 all my ECW files can be loaded without any problem. Is there anything that I miss out or any changes that I need to do in ver 10?
Below are the codes that I use:
private void LoadMap_MapInfoECW(string filename, ListecwFiles)
{
try
{
MainMap.MapUnit = GeographyUnit.DecimalDegree;
//World Map Shape
ShapeFileFeatureLayer worldLayer = new ShapeFileFeatureLayer(string.Format(@"{0}\Countries02\{1}", MapDataPath, "Countries02.shp"));
worldLayer.ZoomLevelSet.ZoomLevel01.DefaultAreaStyle = AreaStyles.CreateSimpleAreaStyle(GeoColor.FromArgb(0xFF, 252, 188, 63));
worldLayer.ZoomLevelSet.ZoomLevel01.ApplyUntilZoomLevel = ApplyUntilZoomLevel.Level20;
LayerOverlay baseMapOverlay = (LayerOverlay)MainMap.Overlays["BaseMapOverlay"];
baseMapOverlay.TileType = TileType.MultipleTile;
baseMapOverlay.Layers.Add(new BackgroundLayer(new GeoSolidBrush(GeoColor.GeographicColors.ShallowOcean)));
baseMapOverlay.Layers.Add("WorldLayer", worldLayer);
if (ecwFiles.Count > 0)
{
for (int x = 0; x < ecwFiles.Count; x++)
{
if (File.Exists(string.Format(@"{0}{1}", MapDataPath, ecwFiles[x])))
{
EcwRasterLayer ecwLayer = new EcwRasterLayer();
ecwLayer.DrawingException += new EventHandler<DrawingExceptionLayerEventArgs>(ecwLayer_DrawingException);
ecwLayer.DrawingExceptionMode = DrawingExceptionMode.DrawException;
ecwLayer.PathFilename = string.Format(@"{0}{1}", MapDataPath, ecwFiles[x]);
baseMapOverlay.Layers.Add(string.Format("{0}_{1}", filename, x.ToString()), ecwLayer);
//this.DisplayErrorMessage("LoadMap_MapInfoECW", ecwLayer.PathFilename);
}
}
}
foreach (Layer layer in baseMapOverlay.Layers)
{
layer.Transparency = Convert.ToSingle(layerTransparency.Value);
}
txtSelectedBaseMap.Text = MapInfoGSTFileNameSelected;
//MainMap.Refresh();
}
catch (Exception exception)
{
this.DisplayErrorMessage("LoadMap_MapInfoECW", exception.Message);
}
}
void ecwLayer_DrawingException(object sender, DrawingExceptionLayerEventArgs e)
{
e.Canvas.Clear(new GeoSolidBrush(GeoColor.FromArgb(128, 255, 192, 203)));
System.Drawing.Bitmap tempImage = new System.Drawing.Bitmap(string.Format("{0}\\ErrorImage.png", MapDataPath));
MemoryStream stream = new MemoryStream();
tempImage.Save(stream, System.Drawing.Imaging.ImageFormat.Png);
stream.Seek(0, SeekOrigin.Begin);
tempImage.Dispose();
e.Canvas.DrawScreenImageWithoutScaling(new GeoImage(stream), e.Canvas.Width / 2, e.Canvas.Height / 2, DrawingLevel.LabelLevel, 0, 0, 0);
e.Cancel = true;
}
Attached are the ecw files sample. I can’t upload all files due to upload size limitation.
