Discussion

This method generates an image with infinite extent. The image pixels values are from one of four independent, uniformly distributed random colors.

The following code creates a filter that generates a random color image:

func random() -> CIImage {
   let randomGenerator = CIFilter.randomGenerator()
   return randomGenerator.outputImage!
}
