Now only a fraction of the original data range is represented by the
total number of colors.
Decreasing the displayed data range produces high contrast.
By holding down the left-right arrows at either end of the Palette Bar you can alter
the minimum and maximum values in the displayed data range independently of
each other, and so adjust the contrast to the level you require. As you hold down the
arrows (place the cursor over an arrow button and hold down the primary mouse
button), observe carefully how the scale changes and how the displayed data range is
affected. If you wish to undo your changes, use Rescale.
Note: When the left-right arrows are held down for a time, you will see the display
flash periodically as the system performs the contrast adjustment. These flashes
occur as the system refreshes the color palette to cover your new displayed data
range. Hold the arrows down until you reach your required contrast level.
You can alter the brightness of the data shown in Image Display Mode by moving
the displayed data range so that it covers higher or lower data values. To move the
displayed data range, place the cursor on or just below the Palette Bar (the cursor
becomes a 'finger') and, holding down the primary mouse button, 'slide' the scale on
the palette to the left or right.
Sliding the scale to the right means that the displayed
data range covers lower data values (the numbers on
the scale decrease). The display becomes brighter.
