| BITS | Number of bits for the output DN |
Files: FROM
Description
Input filename of a messenger cube file to be exported into a CDR image.
| Type | cube |
|---|---|
| File Mode | input |
| Filter | *.cub |
Files: TO
Description
Output filename, by default the filename will be generated from the input filename.
| Type | filename |

| File Mode | output |
Stretch: TYPE
Description
This parameter is used to select one of two ways to stretch output pixels. They are AUTOMATIC or MANUAL.
| Type | string | |||||||||
|---|---|---|---|---|---|---|---|---|---|---|
| Default | AUTOMATIC | |||||||||
| Option List: |

Stretch: MIN
Description
Lower bound for the manually specified stretch.
| Type | double |
|---|
Stretch: MAX
Description
Upper bound for the manually specified stretch.
| Type | double |
|---|
Stretch: MINPER
Description
The cumulative percentage value to be mapped to the minimum valid pixel for the specified number of bits. For example, with BITS=10 and MINPER=1.0, the DN which corresponds to the cumulative percent of 1.0 will be mapped to 3, where 0 represents NULL, 1 represents LRS and 2 represents LIS.
| Type | double |
|---|---|
| Default | 0.0 |
| Minimum | 0.0 (inclusive) |
| Maximum | 100.0 (inclusive) |
| Less Than or Equal |
|
Stretch: MAXPER
Description
The cumulative percentage value to be mapped to the maximum valid pixel for the specified number of bits. For example, with BITS=10 and MINPER=99.0, the DN which corresponds to the cumulative percent of 99.0 will be mapped to 1021, 1021=(2**bits)-1-2. Where 1023 represents HIS and 1022 represents HRS.
| Type | double |
|---|---|
| Default | 100.0 |
| Minimum | 0.0 (inclusive) |
| Maximum | 100.0 (inclusive) |
| Greater Than or Equal |

Output Controls: BITS
Description
The number of bits to compress the input data to. The valid data as well as the five special pixel values (NULL, LIS, LRS, HIS, HRS) will be compressed to this number of bits. The output data type will be automatically chosen using this value. A value of 8 will create unsigned byte output files. Values from 9 to 16 will create unsigned word output files. Unused bits in the unsigned word output file will be set to zero.
| Type | integer |
|---|---|
| Default | 32 |
| Minimum | 8 (inclusive) |
| Maximum | 32 (inclusive) |
History
| Christopher Austin | 2008-08-12 | Original version |
| Christopher Austin | 2008-08-14 | Shortened and optimized the code handling the histograms. Removed the 32 bit stretch. |
| Christopher Austin | 2008-08-22 | Fixed for correct source. Previously was using incorrect comparison data. |
| Kris Becker | 2008-09-03 | Modified sources of some of the keywords for the translation. Honors existing software name and versions if they exist; only include the High Instrument Saturation count in the SATURATED_PIXEL_COUNT label keyword where before it included all special pixels. |
| Kris Becker | 2008-09-08 | Corrected the determination of minimum/maximum data ranges when using the histogram. The issue involves specifying MAXPER=100.0 and it not producing the entire valid range of data. This may result in HRS pixels. It has been changed to use the full valid data range in as computed from the Histogram. |
| Kris Becker | 2008-09-19 | Fixed N/A quoting, misplaced units and data values that exceeded 20 characters. Also quoted the SOFTWARE_VERSION_ID and FILTER_NUMBER keyword values. Added units to RETICLE_POINT_* keywords were missing. |
| Steven Lambright | 2011-03-31 | The DarkStripMean keyword can now be "N/A" |
| Kris Becker | 2011-06-15 | Added ORBIT_NUMBER to translation table for inclusion in output RDR (CDR) file. |
| Kris Becker | 2011-07-21 | Added quotes to the SITE_ID keyword. |
| Jeannie Backer | 2015-09-01 | Added MESS:EC_FACTOR keyword to output label. Increased software version number to 1.1. Made code more compliant with ISIS coding standards. Added PDS format template for the output CDR product. Fixes #2333 |
