How to create a Geometry function dataset

Creating a Geometry function dataset

To create a Geometry function dataset, follow these steps:
  1. Create the Function Arguments object.
  2. Create a Raster Function object.
  3. Create a Function Raster Dataset object.
  4. Create a name object for the function raster dataset.
  5. Specify the output file name for the new dataset.
  6. Initialize the new function raster dataset with the raster function and its arguments.
The following code example shows how to create a Geometry function raster dataset by applying the Geometry raster function to an image:
[C#] 
// Create the Function Arguments object.
IGeometricFunctionArguments rasterFunctionArguments = (IGeometricFunctionArguments)
    new GeometricFunctionArguments();
// The input data and DEM data can be of type IRasterDataset, IRasterBand, or IRaster.
rasterFunctionArguments.DEM = demData;
rasterFunctionArguments.Raster = inputData;

// Create the Raster Function object.
IRasterFunction rasterFunction = new GeometricFunction();
// Create the Function Raster Dataset object.
IFunctionRasterDataset functionRasterDataset = new FunctionRasterDataset();
// Create a name object for the Function Raster Dataset.
IFunctionRasterDatasetName functionRasterDatasetName = (IFunctionRasterDatasetName)
    new FunctionRasterDatasetName();
// Specify the output file name for the new dataset (including the .afr extension at the end).
functionRasterDatasetName.FullName = @"c:\temp\Geometry.afr";
functionRasterDataset.FullName = (IName)functionRasterDatasetName;
// Initialize the new Function Raster Dataset with the Raster Function and its arguments.
functionRasterDataset.Init(rasterFunction, rasterFunctionArguments);
[VB.NET] 
' Create the Function Arguments object.
Dim rasterFunctionArguments As IGeometricFunctionArguments
rasterFunctionArguments = New GeometricFunctionArguments()
' The input data and DEM data can be of type IRasterDataset, IRasterBand, or IRaster.
rasterFunctionArguments.DEM = demDataset
rasterFunctionArguments.Raster = inputData

' Create the Raster Function object.
Dim rasterFunction As IRasterFunction
rasterFunction = New GeometricFunction()
' Create the Function Raster Dataset object.
Dim functionRasterDataset As IFunctionRasterDataset
functionRasterDataset = New FunctionRasterDataset()
' Create a name object for the Function Raster Dataset.
Dim functionRasterDatasetName As IFunctionRasterDatasetName
functionRasterDatasetName = New FunctionRasterDatasetName()
' Specify the output file name for the new dataset (including the .afr extension at the end).
functionRasterDatasetName.FullName = "c:\temp\Geometry.afr"
functionRasterDataset.FullName = functionRasterDatasetName
' Initialize the new Function Raster Dataset with the Raster Function and its arguments.
functionRasterDataset.Init(rasterFunction, rasterFunctionArguments)
