Displacement Map (PB only)


    This effect distorts a layer by displacing pixels horizontally and vertically based on the color values of pixels in a second layer, called the displacement map. The type of distortion created by the Displacement Map effect can vary greatly, depending on the displacement map and options you select. Maximum displacement occurs only when the value of the specified color property is either 0 or 255. Values between 0 and 255 produce displacements calculated using the equation below. Negative values reverse the direction of displacement.

    Displacement amount = maximum_displacement * (2 * (color value - 128)/256)
