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.

TAGS

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.
