Zoom interval
Sets the zoom value, i.e. the upper limit for the graduated
scale. The zoom value is linked to the depth value.
The upper limit value = the lower limit value for depth -
the zoom value. If the lower limit value for depth is less
than the zoom value the upper limit value will be 0. If zoom
is disabled the upper limit value is 0. If the zoom value is
between 1–45 the following applies: the upper limit value =
the lower limit value for depth - the zoom value; the shown
area is then the same as the zoom value. If for example the
depth interval is set to 15 m and the zoom value is set to
10 m, then the lower limit value on the graduated scale is
15 m. The upper limit value is 5 m, which is the difference
between 15 and 10. In other words the image shows a
depth of 5 to 15 metres, and nothing outside of this interval
is shown.
