CIColorControls Class
Definition
The CIColorControls CoreImage filter
public class CIColorControls : CoreImage.CIFilter
type CIColorControls = class
inherit CIFilter
- Inheritance
Remarks
The following example shows this filter in use
// Load our Image from a file
CIImage flower = CIImage.FromCGImage (UIImage.FromFile ("flower.png").CGImage);
// Create the CIColorControls Filter
var colorCtrls = new CIColorControls ()
{
Image = flower,
Brightness = .5F, // Min: 0 Max: 2
Saturation = 1.2F, // Min: -1 Max: 1
Contrast = 3.1F // Min: 0 Max: 4
};
// Get the Resulting image from the filter
return colorCtrls.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);
