isis2raw
Exports a cube to raw format
This program will export an ISIS cube to a grayscale raw formatted file.
The raw image may be output into an 8-bit, 16-bit unsigned, 16-bit signed
or 32-bit raw image. This raw image can be in BSQ, BIL, or BIP format, and
can include or exclude Null, LRS, LIS, HIS, and/or HRS specific DN values.
If no special pixel parameters are selected, then Low Saturation values and
Null values are set to black and High Saturation values are set to white.
To ensure acceptable contrast in the output file, the user may select from
three stretch options are given 1) no stretch 2) linear, and 3) manual.
A custom maximum and minimum DN value can be specified for all output
bittypes. For example, if a range of 0 to 1023 is selected in a 16-bit
unsigned raw image, the DNs are stretched to an effective 10-bit format.

| Drew Davidson | 2005-06-14 | Rewrote to support changes in underlying ProcessExport class |
| Drew Davidson | 2005-06-15 | Added code to export multiple bands |
| Jeff Anderson | 2006-05-15 | Modified to allow histogram percentage to be selected for linear stretch option |
| Steven Lambright | 2007-06-15 | Updated documentation to follow current standards |
| Steven Koechle | 2007-09-18 | Fixed problem where the valid data range overlapped the null value. |
| Christopher Austin | 2007-12-17 | Created options to ouput BIL and BIP formats, making BSQ the default, as well as added preserve special pixel (NULL) option. |
| Christopher Austin | 2008-06-10 | Created the options LRS, LIS, HIS, HRS, as well as OMIN and OMAX. Also remade the GUI, and redid much of the documentation. |
| Christopher Austin | 2008-07-07 | Clarified some documentation and updated comments. |
| Makayla Shepherd | 2015-09-01 | Modified to fix an error when inputing OMIN and OMAX values for a 32-bit output image. OMIN and OMAX are now calculated based on the stretch if 32-bit is chosen and the OMIN and OMAX fields are left blank. Fixes #2194. |
| Adam Paquette | 2020-09-04 | Updated application logic to not generate a histogram if stretch is None and the output bit type is 32-bit. Also removes duplicate calls to checkRange and setRangeAndPixels. Closes #3878 (github). |
