This specifies if the image will be trimmed based on the photometric angles obtained from the DEM surface or the ellipsoid. If this parameter is set to false, then the photometric angles will be obtained from the ellipsoidal surface.

Trimming an ISIS cube using the ellipsoid model
Example GUI Screenshot of the photrim GUI with a max emission angle of 88. The reset of the parameters are set to the program defaults. |
Input Cube
Parameter Name:
FROM The untrimmed cube. This is an oblique view of the moon acquired by the Apollo Metric camera. |
Output Cube
Parameter Name:
TO The result of trimming the cube using the ellipsoid model and a max emission angle of 88. |
Trimming an ISIS cube using the digital elevation model.
Example Gui Screenshot of the photrim GUI with a max emission angle of 88 degrees and with the option to use the digital elevation model selected. The rest of the parameters are set to the defaults. |

Tammy Becker | 1999-02-11 | Original version |
Stuart Sides | 2003-06-04 | Converted trimandle to Isis 3.0, and made it trim only on phase, incidence and emission angles. |
Stuart Sides | 2003-07-29 | Modified filename parameters to be cube parameters where necessary |
Steven Lambright | 2008-05-13 | Removed references to CubeInfo |
Marjorie Hahn | 2016-08-05 | Added the option to use the digital elevation model when trimming the image. Created examples for using the DEM and not using the DEM. Fixes #4181. |
