GradientFade
class GradientFade extends StrengthEffectAction
Class GradientFade
Applies a gradient fade effect from one edge of the image.
Use ->horizontalStartPoint() for x or ->verticalStartPoint() for y to indicate from which edge to fade and how much of the image should be faded. Values of x and y can be specified as a percentage (Range: 0.0 to 1.0), or in pixels (integer values). Positive values fade from the top (y) or left (x). Negative values fade from the bottom (y) or right (x). By default, the gradient is applied to the top 50% of the image (y = 0.5). Only one direction can be specified but the fade can be applied symmetrically using the mode qualifier. To apply different amounts of fade to multiple edges, use chained fade effects.
