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
