Discussion

This method applies the hue-adjust filter to an image. The effect changes the hue or color of the pixels by using the angle to modify the image’s color data.

The hue-adjust filter uses the following properties:

angle

A float representing the angle in radians to adjust the current hue of the image as an NSNumber.

inputImage

An image with the type CIImage.

The following code creates a filter that shifts the hue of the image by 5 radians.

func hueAdjust(inputImage: CIImage) -> CIImage {
    let hueAdjustFilter = CIFilter.hueAdjust()
    hueAdjustFilter.inputImage = inputImage
    hueAdjustFilter.angle = 5
    return hueAdjustFilter.outputImage!
}
