Remarks
The following example shows this filter in use
// Create a CIImage from a file.
CIImage flower = CIImage.FromCGImage (UIImage.FromFile ("flower.png").CGImage);
// Construct the HighlightShadowAdjust filter
var shadowAdjust = new CIHighlightShadowAdjust ()
{
Image = flower,
HighlightAmount = .75F, // Default is 1
ShadowAmount = 1.5F // Default is 0
};
// Get the adjusted image
var output = shadowAdjust.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);
