How to create a ColormapToRGB function dataset


Creating a ColormapToRGB function dataset

To create a ColormapToRGB function dataset, follow these steps:
  1. Create a Raster Function object.
  2. Create a Function Raster Dataset object.
  3. Create a name object for the function raster dataset.
  4. Specify the output file name for the new dataset.
  5. Initialize the new function raster dataset with the raster function and its input.
The following code example shows how to create a ColormapToRGB function raster dataset by applying the ColormapToRGB raster function to an image:
[C#]
// Create the Raster Function object.
IRasterFunction rasterFunction=new ColormapToRGBFunction();
// 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\ColormapToRGB.afr";
functionRasterDataset.FullName=(IName)functionRasterDatasetName;
// Initialize the new Function Raster Dataset with the Raster Function and its input. 
// The input data can be of type IRasterDataset, IRasterBand, or IRaster.
functionRasterDataset.Init(rasterFunction, inputData);
[VB.NET]
' Create the Raster Function object.
Dim rasterFunction As IRasterFunction
rasterFunction=New ColormapToRGBFunction()
' 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 filename for the new dataset (including the .afr extension at the end).
functionRasterDatasetName.FullName="c:\temp\ColormapToRGB.afr"
functionRasterDataset.FullName=functionRasterDatasetName
' Initialize the new Function Raster Dataset with the Raster Function and its input.
' The input data can be of type IRasterDataset, IRasterBand, or IRaster.
functionRasterDataset.Init(rasterFunction, inputData)
