How to create a Shaded Relief function dataset (ArcObjects .NET 10.5 SDK)

Creating a Shaded Relief function dataset

To create a Shaded Relief function dataset, follow these steps:

Create the Function Arguments object.
Set the color ramp.
Create a Raster Function object.
Create a Function Raster Dataset object.
Create a name object for the function raster dataset.
Specify the output file name for the new dataset.
Initialize the new function raster dataset with the raster function and its arguments.

The following code example shows how to create a Shaded Relief function raster dataset by applying the Shaded Relief raster function to an image:

[C#]

// Create the Function Arguments object.
IShadedReliefFunctionArguments rasterFunctionArguments=
    (IShadedReliefFunctionArguments)new ShadedReliefFunctionArguments();
// The input data can be of type IRasterDataset, IRasterBand, or IRaster.
rasterFunctionArguments.Raster=inputData;
// The colorRamp object is of type IColorRamp.
rasterFunctionArguments.ColorRamp=colorRamp;

// Create the Raster Function object.
IRasterFunction rasterFunction=new ShadedReliefFunction();
// 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\ShadedRelief.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 IShadedReliefFunctionArguments
rasterFunctionArguments=New ShadedReliefFunctionArguments()
' The input data can be of type IRasterDataset, IRasterBand, or IRaster.
rasterFunctionArguments.Raster=inputData
' The colorRamp object is of type IColorRamp.
rasterFunctionArguments.ColorRamp=colorRamp

' Create the Raster Function object.
Dim rasterFunction As IRasterFunction
rasterFunction=New ShadedReliefFunction()
' 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\ShadedRelief.afr"
functionRasterDataset.FullName=functionRasterDatasetName
' Initialize the new Function Raster Dataset with the Raster Function and its arguments.
functionRasterDataset.Init(rasterFunction, rasterFunctionArguments)
