C# Example
// Create a CIImage from a file. CIImage flower = CIImage.FromCGImage (UIImage.FromFile ("flower.png").CGImage); // Construct the WhitePointAdjust filter var whitePointAdjust = new CIWhitePointAdjust() { Image = flower, Color = new CIColor(new CGColor(255F, 0, 187F)) // A Magenta Color }; // Get the adjusted image from the filter. var output = whitePointAdjust.OutputImage; // To render the results, we need to create a context, and then // use one of the context rendering APIs, in this case, we render the // result into a CoreGraphics image, which is merely a useful representation // var context = CIContext.FromOptions (null); var cgimage = context.CreateCGImage (output, output.Extent); // The above cgimage can be added to a screen view, for example, this // would add it to a UIImageView on the screen: myImageView.Image = UIImage.FromImage (cgimage);
