Ranger Studio
The Levels sliders to the left in each tab can be used for visualizing only a certain range of
measurement values. The right slider sets the highest value to visualize, and the left slider
the lowest value. Measurement values within the range will be translated to the 255
available grayscale values, and the values outside the range will be displayed as black (1)
or white (255).
This can be useful for example when studying small range variations on a part of an object
that varies a lot in height. By adjusting the levels, the variations can be easier to view in
the visualization image, while parts higher or lower than the selected range are ignored.

Levels settings.
