ExtractBandsFromRaster Task

This task extracts an array of single-band rasters from an ENVI raster, with each band represented as a separate 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

Syntax

Result = ENVITask('ExtractBandsFromRaster')

Input parameters (Set, Get): INPUT_RASTER

Output parameters (Get only): OUTPUT_RASTERS

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.
