Static Contrast Mode
The static contrast mode maps a fixed range in the 16-bit image to 8-bit values. The
minimum and maximum input values (contrastMinValue and contrastMaxValue features)
specifiy the range of values in the 16-bit image. If the image scene contents are known
to always fall within a specific range, this mode can be used to provide consistent
mapping of values.
Note: If the image pixel data moves outside this range, the information is lost and
rendered as either 0 or 255 (pixel data below the range is mapped to 0, above the
range mapped to 255).
For example, in the following image, the 16-bit histogram shows that the pixel range
between the minimum and maximum values present is 147 DN.
