ExtractBandsFromRaster Task

This task extracts individual bands from an ENVI raster.

Example

This example opens a raster from sample data included with your installation of ENVI and then extracts all the individual bands, returning them each as ENVI rasters.

; Start the application

e = ENVI()

File = Filepath('qb_boulder_msi', SUBDIRECTORY=['data'], $

ROOT_DIR = e.Root_Dir)

; Create a raster series object

Raster = e.OpenRaster(File)

; Get the task from the catalog of ENVITasks

Task = ENVITask('ExtractBandsFromRaster')

; Define inputs

Task.INPUT_RASTER = Raster

; Run the task

Task.Execute

; Get the bands of the input raster

RasterBands = Task.OUTPUT_RASTERS
