## Discussion

Discussion This method generates a text image. The effect takes the input string property and the scale factor to scale up the text. You commonly combine this filter with other filters to create a watermark on images. The text image generator filter uses the following properties: The following code creates a filter that generates a string of text as a grayscale image: func textImage(inputText: String) -> CIImage {     let textImageGenerator = CIFilter.textImageGenerator()     textImageGenerator.text = inputText     textImageGenerator.fontName = "Helvetica"     textImageGenerator.fontSize = 25     textImageGenerator.scaleFactor = 4     return textImageGenerator.outputImage! }
