RasterColormapToRGBConverter A helper class for converting between colormap to RGB raster.

Remarks

IRasterColormapToRGBConversion provides access to methods that convert between a raster datset that has a colormap and a three-band raster dataset. The pOutWorkspace parameter can only be a raster workspace, which means that the output can only be a file-based raster dataset.

The ColormapToRGB method converts a raster dataset that has a colormap to a three-band raster dataset by mapping the color red, green and blue in the colormap table to the red, green and blue bands of the raster dataset.

The CreateRGBRaster method creates a Raster that contains three bands, which can be saved using ISaveAs.

The RGBToColormap method converts a three-band raster dataset to a colormap raster dataset.

The RGBRasterToColormap method takes a Raster as input and coverts to a raster dataset that contains a colormap.
