Hi,
I need to create an animation from sequence of .jpg images in Globe. When new image is added, old one should be deleted. Images aren't georeferenced, but I have 4 points indicating where they should be placed.
I tried the following:
public partial class ArcGISHostControl : UserControl
{
Dictionary<string, ILayer> _mainElementRepository;
string workspace = "C:\\temp\\";
IWorkspaceFactory wpf;
IRasterWorkspace rasterworkspace;
public ArcGISHostControl()
{
InitializeComponent();
_mainElementRepository = new Dictionary<string, ILayer>();
AddBaseLayer(); //adds base maps
wpf = new RasterWorkspaceFactory();
raswp = wpf.OpenFromFile(workspace, 0) as IRasterWorkspace;
}
private string AddNewImage(IPointCollection sourcePoints, IPointCollection targetPoints, string file, string oldID)
{
string id = generateID();
IRasterLayer layer = GeoreferenceImage(file, sourcePoints, targetPoints);
axGlobeControl.Globe.AddLayerType(layer as ESRI.ArcGIS.Carto.ILayer, esriGlobeLayerType.esriGlobeLayerTypeDraped, true);
_mainElementRepository.Add(id, layer);
DeleteObject(oldID);
return id;
}
private IRasterLayer GeoreferenceImage(string file, IPointCollection sourcePoints, IPointCollection targetPoints)
{
IRasterDataset2 rasterDataset;
rasterDataset = rasterworkspace.OpenRasterDataset(file) as IRasterDataset2;
IRasterGeometryProc rasterPropc = new RasterGeometryProcClass();
IRaster raster = rasterDataset.CreateFullRaster();
rasterPropc.Warp(sourcePoints, targetPoints, esriGeoTransTypeEnum.esriGeoTransProjective, raster);
rasterPropc.Register(raster);
IRasterLayer layer = new RasterLayerClass();
layer.CreateFromRaster(raster);
return layer;
}
public void DeleteImage(string id)
{
ILayer forDeletion;
if (_mainElementRepository.TryGetValue(id, out forDeletion))
{
axGlobeControl.Globe.GlobeDisplay.Scene.DeleteLayer(forDeletion);
_mainElementRepository.Remove(id);
}
}
}
Problem is that this is very slow, and causes GUI to become nonresponive.
Is there a better way to do this?
