BuildRasterPyramids Task
This task creates pyramid files for rasters. Pyramids are copies of the data at various reduced resolutions, used to speed image display.
Example
; Start the application
e = ENVI()
; Open an input file
File = Filepath('qb_boulder_msi', Subdir=['data'], $
Root_Dir=e.Root_Dir)
Raster = e.OpenRaster(File)
; Get the task from the catalog of ENVITasks
Task = ENVITask('BuildRasterPyramids')
; Define inputs
Task.INPUT_RASTER = Raster
; Run the task
Task.Execute
; Verify that the pyramid exists
Print, Raster.PYRAMID_EXISTS
