After the vector contour lines are created, you can turn off the image display to see the lines more clearly.
To hide the image display:
Open the Data Manager if it is not already open by selecting View | Toolbars/Managers | Data Manager. The Data Manager is open if it has a check mark next to it. The Data Manager is typically displayed at the bottom of the Didger window.
Images are displayed in the Data Manager with this symbol: . The image should be at the bottom of the Object Type list.
The light bulb symbol is yellow, indicating the image is displayed. Click on the light bulb so that it changes to gray. This turns off the image so the vector contour lines can be seen easily.
Click on the light bulb next to the image to turn the image display off.
