The following example shows this filter in use

C# Example

// Create CIImages from files.
CIImage clouds = CIImage.FromCGImage (UIImage.FromFile ("clouds.jpg").CGImage);
CIImage heron = CIImage.FromCGImage (UIImage.FromFile ("heron.jpg").CGImage);

// Construct the SourceInComposite filter        
var sourceComposite = new CISourceInCompositing()
	Image = clouds, // This image will be Cropped
	BackgroundImage = heron

// Get the composite image from the filter
var output = sourceComposite.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);
