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 parameters (Set, Get): DATA_IGNORE_VALUE, INPUT_RASTER, NITF_COMPRESSION, OUTPUT_RASTER_URI

Output parameters (Get only): OUTPUT_RASTER

Parameters marked as "Set" are those that you can set to specific values. You can also retrieve their current values any time. Parameters marked as "Get" are those whose values you can retrieve but not set.

Input Parameters

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_URI (optional)

Specify a string with the fully qualified filename and path of the associated OUTPUT_RASTER.

If you do not specify this parameter, or set it to an exclamation symbol (!), ENVI creates a temporary file.
If you set it to the hash symbol (#), ENVI creates a file in the temporary directory, but this file will not be deleted when ENVI closes.
