ExportRasterToNSIF10 Task

This task exports a raster to NSIF 1.0 file format.

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)

; Get the task from the catalog of ENVITasks

Task = ENVITask('ExportRasterToNSIF10')

; Define inputs

Task.INPUT_RASTER = Raster

; Run the task

Task.Execute

; Get the collection of data objects currently available in the Data Manager

DataColl = e.Data

; Add the output to the Data Manager

DataColl.Add, Task.OUTPUT_RASTER

; Display the result

View = e.GetView()

Layer = View.CreateLayer(Task.OUTPUT_RASTER)

Syntax

Result = ENVITask('ExportRasterToNSIF10')

Input properties (Set, Get): DATA_IGNORE_VALUE, INPUT_RASTER, NITF_COMPRESSION, OUTPUT_RASTER_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.

Methods

This task inherits the following methods from ENVITask:

Properties

This task inherits the following properties from ENVITask:

COMMUTE_ON_DOWNSAMPLE

DATA_IGNORE_VALUE (optional)

Specify a unique data value for pixels in the output raster that have a non-zero pixel state value. See Raster Pixel State for more information.

INPUT_RASTER (required)

Specify a raster to export to NSIF 1.0 format.

NITF_COMPRESSION(optional)

Specifies the NITF compression type. The choices are as follows:

If the data type is byte, integer, unsigned integer, long integer, or unsigned long integer, the following options will work:

EPJE Num Lossless
EPJE Vis Lossless
NPJE Num Lossless
NPJE Vis Lossless
Transcode EPJE to NPJE: Only works for NITF files that are C8-compressed and are not spatially subsetted
Transcode NPJE to EPJE: Only works for NITF files that are C8-compressed and are not spatially subsetted

The following options work for rasters that have one or three bands, and the data type is byte:

JPEG DCT (High)
JPEG DCT (Low)
JPEG DCT (Medium)

The default value is No Compression.

OUTPUT_RASTER

This is an object reference to the output raster, of filetype NITF.

OUTPUT_RASTER_URI (required)

Specify a string with the fully qualified filename and path of the associated OUTPUT_RASTER. If you do not specify this property, or set it to an exclamation symbol (!), a temporary file will be created.
