Adjusting the Brightness
Depending on your data values and the color table chosen, you may want to adjust the brightness of your image for a better view. Brightness refers to the positioning of the center point in the color table relative to the minimum and maximum color indices. The brightness value represents a percentage position (0 to 100%), not a specific color index in the color table.
 
note
The brightness and contrast controls are related; contrast defines the range of available color table values that is centered around the brightness setting.
The brightness is controlled by a slider in the controls area of the WzImage window. The brightness control can be adjusted any of these three ways.
*Click and drag MB1 on the brightness slider.
*Position the pointer in the brightness slider track and click MB1. The slider is adjusted by 10% of the maximum slider value for each MB1 click.
*Double click MB1 in the brightness slider text field and type in the desired brightness value. Press <Return> to apply the new value.
