Distortion
The Distortion palette allows you to control the distortion view. When enabled, it shows the compensated image based on the current settings in the Distortion palette.
You can toggle between the distorted and not-distorted views. To view the distortion, you must zoom in higher resolutions.
NOTE: This option is only available for Security jobs and requires a special license.
