This task exports raster color slices to a density slice range (DSR) file.
Example
e = ENVI()
File = FILEPATH('AVIRISReflectanceSubset.dat', $
ROOT_DIR=e.ROOT_DIR, $
SUBDIRECTORY=['data', 'hyperspectral'])
Raster = e.OpenRaster(File)
SITask = ENVITask('SpectralIndex')
SITask.INPUT_RASTER = Raster
SITask.INDEX = 'Red Edge Normalized Difference Vegetation Index'
SITask.Execute
DataColl = e.Data
DataColl.Add, SITask.OUTPUT_RASTER

Syntax
Result = ENVITask('ExportColorSlices')
Input parameters (Set, Get): COLORS, OUTPUT_DSR_URI, RANGES
Output parameters (Get only): None
Parameters marked as "Set" are those that you can set to specific values. You can also retrieve their current values any time. Parameters marked as "Get" are those whose values you can retrieve but not set.
Input Parameters
COLORS (required)
Specify a (3 x n) byte array of RGB color triplets, where n is the number of ranges set in the RANGES parameter.
OUTPUT_DSR_URI (required)
Specify a string with the fully qualified path and filename for the exported DSR file.
RANGES (required)
Specify a (2 x n) double-precision array of color slice ranges, where n is the number of colors set in the COLORS parameter.
