height	0 ... display height (0 = full height)	vertical value for the area to be adjusted

Adjusts the color values of all pixels in the area specified by width and height, beginning from the current cursor position. The value for any selected modification has to be set in advance and the corresponding mode must be set:

mode
ADJUST_BRIGHTNESS (see Attribute.setBrightnessAdjustment(int))
ADJUST_CONTRAST (see Attribute.setContrastAdjustment(int))
ADJUST_HUE (see Attribute.setHueAdjustment(int))
ADJUST_SATURATION (see Attribute.setSaturationAdjustment(int))
ADJUST_INVERT

• All adjustment modifications can be combined and changed simultaneously with this method.
• The modifications are processed in the following order: invert - hue/saturation - brightness/contrast.
• This method can be used to dim or brighten part of the screen by adjusting brightness and contrast of an area.
• If the values for width and/or height exceed the right or bottom margin, the controller corrects the values accordingly without throwing an exception.

Example

Draw.adjustDisplayArea(Draw.ADJUST_HUE |
                       Draw.ADJUST_SATURATION,
                       200, 100);
