The following example shows this filter in use
C# Example
// Create a CISmoothLinearGradient filter with the input image var point0 = new CIVector(0, 0); // Default [0 0] var point1 = new CIVector(250, 250); // Default [200 200] var smoothLinear_gradient = new CISmoothLinearGradient() { Point0 = point0, Point1 = point1, Color0 = new CIColor (UIColor.Red), Color1 = new CIColor (UIColor.Blue) }; // Get the altered image from the filter var output = new CICrop { Image = smoothLinear_gradient.OutputImage, Rectangle = new CIVector (0, 0, 400, 300) }.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);
Produces the following output:
