C# Example
// Create the CIImage from a file CIImage xamarinCheck = CIImage.FromCGImage (UIImage.FromFile ("XamarinCheck.png").CGImage); var width = xamarinCheck.Extent.Width; var height = xamarinCheck.Extent.Height; // Create a CIBumpDistortion filter with the input image, center raduis and scale var bump_distortion = new CIBumpDistortion () { Image = xamarinCheck, Center = new CIVector (width/2f, height/2f), Radius = .4f * height, Scale = .5f }; // Get the distorted image from the filter var output = bump_distortion.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);
