Examples
Example 1
Crop NULL pixels
Description
Command Line
GUI Screenshot
cropspecial gui
|
Example GUI Screenshot of GUI with the default parameter settings, ready to perform a crop on the NULL pixels contained within the first band of the input cube. |

Input image for cropspecial
Parameter Name:
FROM The original, 82x361 image. NULL, HRS, LRS, HIS, and LIS pixels are shown in blue, light green, yellow, pink, and light blue, respectively. NULL SPACE is shown here in black. |
Output Image
Output image showing results on the default settings

Output image for cropspecial
Parameter Name:
TO This is the 82x315 output image that results. The NULL pixels at the bottom have been removed, but the NULL pixels surrounded by saturation pixels have not been removed as doing so would result in the loss of pixels not selected for cropping. |
Example 2
Crop all special pixels
Description
Command Line
GUI Screenshot
cropspecial gui
|
Example GUI Screenshot of GUI with parameters filled in to perform a crop on all special pixels contained within the first band of the input cube. |

Output image for cropspecial
Parameter Name:
TO This is the 22x173 output image that results. Some HRS, HIS, and NULL pixels are still present due to the rectangular dimensions of the cube, but their occurence has been minimized. |
History
| Travis Addair | 2009-02-24 | Original version |
| Janet Barrett | 2009-10-22 | Now uses the SubArea class to produce output cube labels with corrected Mapping, Instrument, and AlphaCube groups. |
| Travis Addair | 2010-01-06 | Changed Progress to tell the user when the program is finding the perimeter and when it is removing special pixels from the image. |
