Averaging by scan lines

The average value of the height along each scan (line along X direction) line is calculated. Then the scan lines are put upper or lower so that in the new image the average height along each scan line is the same. This averaging is performed using Command Adjust Scan or button into two ways: By Selection and In Selection . The difference between these two ways will appear if you select in advance a region on the surface. In Selection option will perform averaging only in the selected region, the outer surface will not be modified. By Selection option will average all the image according to the data which is placed in the column, the width of which is equal to the width of the selected area. The Button on the Tool Bar corresponds to the option By Selection.
