How to create a ColorspaceConversion function dataset


Creating a ColorspaceConversion function dataset

To create a ColorspaceConversion function dataset, follow these steps:
  1. Create the Function Arguments object.
  2. Set the type of conversion to be performed.
  3. Create a Raster Function object.
  4. Create a Function Raster Dataset object.
  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 ColorspaceConversion function raster dataset by applying the ColorspaceConversion raster function to an image:
[C#]
// Create the Function Arguments object.
IColorspaceConversionFunctionArguments rasterFunctionArguments=
    (IColorspaceConversionFunctionArguments)new
    ColorspaceConversionFunctionArguments();
// The input data can be of type IRasterDataset, IRasterBand, or IRaster.
rasterFunctionArguments.Raster=inputData;
// Set the type of conversion you want to perform.
rasterFunctionArguments.ConversionType =
    esriColorspaceConversionType.esriColorspaceConversionRGBToHSV;

// Create the Raster Function object.
IRasterFunction rasterFunction=new ColorspaceConversionFunction();
// 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\ColorspaceConversion.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 IColorspaceConversionFunctionArguments
rasterFunctionArguments=New ColorspaceConversionFunctionArguments()
' The input data can be of type IRasterDataset, IRasterBand, or IRaster.
rasterFunctionArguments.Raster=inputData
' Set the type of conversion you want to perform.
rasterFunctionArguments.ConversionType=esriColorspaceConversionType.esriColorspaceConversionRGBToHSV

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