Angle
Specifies the angle of the wave producer area for the Line and Ring types. This control sets the orientation of
the line and thus controls the initial direction of the waves, which emanate from either side of the line, perpendicular
to its length.
Amplitude
Controls the height of the produced wave. Higher values create more dramatic waves but may result in
clipping, which you can repair by using the Brightness and Contrast controls.
Frequency
Controls how many waves are produced per second. A value of 1 has the effect of waves surfacing once
every second.
Phase
Specifies where in the wave phase the wave actually begins. For example, with the default setting of 0˚, the
first disturbance in the liquid is a convex wave (projecting upward from the surface of the water). With Phase set to
180˚, the first disturbance in the liquid is a concave wave.
Stylize effects
Brush Strokes effect
The Brush Strokes effect applies a rough painted look to an image. You can also use this effect to achieve a pointillist
style by setting the length of the brush strokes to 0 and increasing the stroke density. Although you specify the
direction of strokes, they are scattered randomly by a small amount to give a more natural effect. This effect alters
the alpha channel, as well as the color channels; if you have masked out a portion of the image, the brush strokes
paint over the edges of the mask.
This effect works with 8-bpc color.
Original (left), and with effect applied (right)
Adjust the following controls for the Brush Strokes effect:
Stroke Angle
Specifies the direction in which the strokes are made. The image is effectively shifted in this direction,
which may cause some clipping at the layer boundaries. To avoid this, place the layer you want to brush into a larger
composition, and then apply the Brush Strokes effect to the composition.
Brush Size
Specifies the size of the brush in pixels.
Stroke Length
Indicates the maximum length of each stroke, in pixels. If Stroke Randomness is not 0, the actual
length of any given stroke may be slightly less than this maximum length.
Stroke Density
Higher densities result in overlapping brush strokes and interesting visual effects.
Stroke Randomness
Creates non-uniform strokes. The more randomness, the more the strokes vary from the brush
and stroke settings you’ve specified.
Paint Surface
Specifies where brush strokes are applied. Paint on Original Image puts the strokes on top of the
unmodified layer. This is the default setting. Paint on Transparent causes only the strokes themselves to appear,
