The following example shows this filter in use
C# Example
// Create the CIImage from a file CIImage flower = CIImage.FromCGImage (UIImage.FromFile ("flower.png").CGImage); // Setup the color cube data float [] color_cube_data = { 0, 0, 0, 1, .1f, 0, 1, 1, 0, 1, 0, 1, 1, 1, 0, 1, 0, 0, 1, 1, 1, 0, 1, 1, 0, 1, 1, 1, 1, 1, 1, 1 }; var byteArray = new byte[color_cube_data.Length * 4]; Buffer.BlockCopy(color_cube_data, 0, byteArray, 0, byteArray.Length); var data = NSData.FromArray (byteArray); // Create a CIColorCube filter with the input image var color_cube = new CIColorCube () { Image = flower, CubeDimension = 2, CubeData = data }; // Get the altered image from the filter var output = color_cube.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);
