ENVIRasterLayer::Close

ENVIRasterLayer::Close

The Close method closes the ENVIRasterLayer.

Example


; Launch the application
e = ENVI()
 
; Open a file
file = FILEPATH('qb_boulder_msi', ROOT_DIR=e.ROOT_DIR, $
  SUBDIRECTORY = ['data'])
raster = e.OpenRaster(file)
 
; Display the data
view = e.GetView()
layer = view.CreateLayer(raster)
 
; Close the layer
layer.Close
 
; Create a new layer from the data
layer = view.CreateLayer(raster,/CIR)

Syntax


ENVIRasterLayer.Close [, ERROR=variable]

Keywords


Keywords are applied only during the initial creation of the object.

ERROR

Set this keyword to a named variable that will contain any error message issued during execution of this routine. If no error occurs, the ERROR variable will be set to a null string (''). If an error occurs and the routine is a function, then the function result will be undefined.

When this keyword is not set and an error occurs, ENVI returns to the caller and execution halts. In this case, the error message is contained within !ERROR_STATE and can be caught using IDL's CATCH routine. See IDL Help for more information on !ERROR_STATE and CATCH.

See Manage Errors for more information on error handling in ENVI programming.
