I'm using arcgis 10.2 Java SDK (I'm using ArcObjects NOT the Runtime SDK) try to do a IDW interpolation and I'm following the instruction from
but I got a ClassCastException when I deal with the returned object from IDW operation.
my code is like this:
IInterpolationOp interpolationOP = new RasterInterpolationOp();
IRasterAnalysisEnvironment interpolationEnv = (IRasterAnalysisEnvironment)interpolationOP;
interpolationEnv .setCellSize(esriRasterEnvSettingEnum.esriRasterEnvValue, cellsize);
IRasterRadius radius = new RasterRadius();
radius .setFixed(10, new Integer(0));
IGeoDataset outGeo = interpolationOP.iDW(inputData, power, radius, null);
IRaster raster = (IRaster)outGeo;
RasterLayer rasterLayer = new RasterLayer();
the emphasized line is where the exception occurred. from the help document, it doesn't mention how to convert the geoDataset to a Raster so in my understanding it's a normal Java cast, but I'm wrong.
I also tried the deprecated method :
IRaster raster = new Raster(outGeo);
doesn't work either.
I googled, there are a lot of c# sample code, just using a geoDataset as IRaster will do the trick, but i couldn't find a java sample.
Any idea will be appreciated.
