# Setting Brush Attribute Modes

The value of a brush attribute depends on the selected attribute.

(a) Brush Attribute Mode boxes

Off
  Disables the brush attribute.
Constant
  Keeps the brush attribute values constant.
Pressure
  Uses the pressure exerted on the pen as the reference value. The harder you press on the pen, the greater the brush attribute value. The softer you press, the lower the brush attribute value.
Direction
  Uses the direction of the brush stroke as the reference. When used with the Direction mode, the Direction attribute causes the brush strokes to follow the trajectory of the brush. Increase the value to enhance the effect on brush direction. Drag right to use 100% of the brush attribute value, left to use 0%, up to use 25%, or down to use 75%.

Direction attribute value at 100%, Direction attribute mode | Direction attribute value at 15%, Direction attribute mode

Fade
  Uses the percentage value entered in the Fade field to determine the length of time that elapses before the brush stroke fades. The greater the percentage, the faster the stroke fades. A value of 100 in the Fade field causes the stroke to fade quickly, whereas a value of 1 causes the stroke to last longer. Also, strokes applied quickly will be longer than those applied more slowly.

Pressure attribute value at 100%, Fade attribute mode at 35% | Pressure attribute value at 100%, Fade attribute mode at 85%

Front, Matte, Source Front and Source Matte
  Allows you to use the red channel in a reference image to set brush attributes. Source Front and Source Matte mode use the red channel of the selected source in the Sources list.
