[C#]

This example shows how to create an image server layer from a URL, clip a portion of image and save it to a file.

public static void AccessImageServerLayer()
{
//create an image server layer by passing an URL
IImageServerLayer2 imageserverlayer = new ImageServerLayerClass();
string URL = "http://myserver/arcgis/services/amazon/imageserver";
imageserverlayer.Initialize(URL);

//get raster from the image server layer
IRaster raster = imageserverlayer.Raster;

//raster from image server is normally large, you need to
//define the size of the raster
IRasterProps rasterProps = (IRasterProps)raster;
IEnvelope clipEnvelope = new EnvelopeClass();
clipEnvelope.PutCoords(779000, 9628000, 786000, 9634000);
rasterProps.Extent = clipEnvelope;
rasterProps.Width = 256;
rasterProps.Height = 256;

//save the clipped raster to File Geodatabase
ISaveAs saveas = (ISaveAs)raster;
IWorkspaceFactory workspaceFact = new FileGDBWorkspaceFactoryClass();
IWorkspace workspace = workspaceFact.OpenFromFile("c:\temp\fgdb.gdb",0);
saveas.SaveAs("clipfromimageserverlayer", workspace, "gdb");
}
