C# Example
// Create the CIImage from a file CIImage clouds = CIImage.FromCGImage (UIImage.FromFile ("clouds.jpg").CGImage); CIImage heron = CIImage.FromCGImage (UIImage.FromFile ("heron.jpg").CGImage); // Create a CIBarsSwipeTransition filter with the input image var bars_swipe_transition = new CIBarsSwipeTransition () { Image = heron, TargetImage = clouds, Time = 0.5f }; // Get the transition image from the filter var output = bars_swipe_transition.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);
