Determines the amount of wind lines to place in the image.
Edge

used to detect the edges and the direction of the edge indicators.

image colors, or click the color picker to select a different color.
Wind color Specifies the color of the wind lines. Select the Image check box to use the

Random Seed Indicates the random placement of the wind lines. When you apply the Wind

wind lines different every time you apply the filter. You can define a specific
random seed to generate identical wind lines. To generate a new random seed,
click Random Seed.
