This method retrieves the current raster so that you can work with it like any other ENVIRaster. Use the Set method to set the current raster.


; Start the application
e = ENVI()
; Locate a raster series file
seriesFile = Filepath('AirTemp.series', Subdir=['data','time_series'], $
  Root_Dir = e.Root_Dir)
; Create a raster series object
series = ENVIRasterSeries(seriesFile)
; Print the contents of the series file
PRINT, series
; Set the current raster to be the beginning 
; of 31 December (Index #8)
series.Set, 8
; Get the current raster
Dec31Raster = series.Raster
; View the current raster
View1 = e.GetView()
Layer1 = View1.CreateLayer(Dec31Raster)


Result = ENVIRasterSeries.Raster



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.
