The Distortion effects can help you to bloat, squeeze, bend, pull up, or twist the shape of an object or a group of objects.
There are four Distortion effects to choose from:
The Bulge effect creates a bump on an object or photo.
You can control the size of the bump with the Radius (3) slider.
The Strength (4) slider controls the intensity and direction of the effect.
A positive strength value projects outward.
A negative strength value projects inward.
You can move the bump horizontally by dragging the Center X (1) slider.
The Center Y (2) slider moves the bumb vertically.
The Fisheye effect creates a curved distortion of the object. It simulates the fisheye lens warping the photo as if you are looking into googles while diving into underwater deep.
The Strength slider controls the intensity and direction of the effect.
As with the bulge effect, it has a positive and negative value to direct the effect outward or inward respectively.
The Bend effect allows you to curve the object into the arc.
You may choose to protrude the image to the left or right depending on the value of the Strength X slider.
The Strength Y slider controls the vertical protrusion of the image. A positive value bends upward; a negative value bends downward.
The Swirl effect twists an image creating the whirl inside of an object.
You can control the horizontal position of the whirl by dragging the Center X (1) slider.
The Center Y (2) slider controls the vertical position of the whirl.
The Radius (3) slider controls the whirl size and intensity of the whirl.
You can also control the direction and intensity of the effect by dragging the Angle (4) slider.
Set the negative value to twist clockwise; set the positive slider to twist counterclockwise.
