CIPinchDistortion

Creates a rectangular-shaped area that pinches source pixels inward, distorting those pixels closest to the rectangle the most.

• -inputImage <image> : The image to use as an input image. For filters that also use a background image, this is the foreground image.
• -inputScale <number> : The amount of pinching. A value of 0.0 has no effect. A value of 1.0 is the maximum pinch. [Default 0.5]
• -inputRadius <number> : The radius determines how many pixels are used to create the distortion. The larger the radius, wider the extent of the distortion. [Default 300]
• -inputCenter <vector> : The x and y position to use as the center of the distortion. [Default 150,150]
