The GetView function method returns the ENVIView where the layer resides.


; Launch the application
e = ENVI()
; Open a raster file and create an ENVIRaster
file1 = FILEPATH('qb_boulder_msi', ROOT_DIR=e.ROOT_DIR, $
  SUBDIRECTORY = ['data'])
raster = e.OpenRaster(file1)
; Open a shapefile and create an ENVIVector
file2 = FILEPATH('states.shp', $
  SUBDIRECTORY = ['examples','data'])
vector = e.OpenVector(file2)
; Display the raster and vector in their own
; respective views
view1 = e.GetView()
layer1 = view1.CreateLayer(raster)
view2 = e.CreateView()
layer2 = view2.CreateLayer(vector)
; Show that layer2 resides in view2
PRINT, view2
PRINT, layer2.GetView()


Result = ENVIVectorLayer.GetView([, ERROR=variable])

Return Value

This method returns the ENVIView where the layer resides.


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


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.
