ExportRasterToPNG Task
This task exports a full-resolution raster to a PNG file.
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)
; Process a spectral subset
Subset = ENVISubsetRaster(Raster, BANDS=[0])
; Get the task from the catalog of ENVITasks
Task = ENVITask('ExportRasterToPNG')
; Define inputs
Task.INPUT_RASTER = Subset
; Run the task
Task.Execute
; Display the result
View = e.GetView()
Layer = View.CreateLayer(Task.OUTPUT_RASTER)
Syntax
Result = ENVITask('ExportRasterToPNG')
Input properties (Set, Get): INPUT_RASTER, OUTPUT_URI
Output properties (Get only): OUTPUT_RASTER
Properties marked as "Set" are those that you can set to specific values. You can also retrieve their current values any time. Properties marked as "Get" are those whose values you can retrieve but not set.

This task inherits the following methods from ENVITask:
Properties
This task inherits the following properties from ENVITask:
This task also contains the following properties:
INPUT_RASTER (required)
Specify a raster to export to PNG. Since a PNG file can only have one or three bands, you must define a spectral subset of one or three bands from the input raster before running the task. See the code example above.
OUTPUT_RASTER
This is an object reference to the output raster, of filetype PNG.
OUTPUT_URI (required)
Specify a string with the fully qualified path and filename for the exported PNG file.
