Displace

Settings

The following settings can be adjusted on the vertical slider:

• Strength—sets the intensity of pixel displacement. Negative values shift pixels upwards, positive values shift pixels downwards.
• Opacity—sets how visible the filter is, e.g. at 1% opacity the filter effect is almost transparent whilst at 100%, it is fully opaque.

The following settings can be adjusted on the context toolbar:

• Beneath—determines the displacement map using layers beneath the selected layer.
• Load Map from file—allows for using one own's images as the basis for pixel mapping.
• Scale To Fit—when enabled, the displacement map stretches or shrinks to fit the document size. If disabled, the displacement map retains its native dimensions.
• Method
  • Red/Green—edge detection based on pixel values and the amount of specified color.
  • Sobel 3x3—edge detection based on 3 by 3 kernel convolution. This method is preferable if you would like to maintain the effect's position. Apply this method before loading the displacement map image.
• Split—when toggled, it allows for a before and after preview mode.
• Merge—applies modifications set by parameters and settings to layers below.
• Reset—rejects and resets filter adjustments to their starting position.
• Protect alpha —allows to control how the edges of a filter behave, e.g. they can be hard, to separate the effect from another object or background. Soft edges, on the other hand, would give a more calmer and stable transition.
