I want to convert WKWebView
or UIWebView
to CIImage
. How can I do it?
UIGraphicsBeginImageContext(image.extent.size)
self.webview.layer.render(in:UIGraphicsGetCurrentContext()!)
let result: CIImage = CIImage(image:
UIGraphicsGetImageFromCurrentImageContext()!, options: nil)!
UIGraphicsEndImageContext()
I did it like this, but it does not work.I expect that the contents of UIWebView
will be displayed in CIImage
. Background color has been displayed.
This can be achieved in 2 steps :
Convert WKWebView
(having base class as UIView
) to UIImageView
extension UIImage { convenience init(view: UIView) { UIGraphicsBeginImageContext(view.frame.size) view.layer.render(in:UIGraphicsGetCurrentContext()!) let image = UIGraphicsGetImageFromCurrentImageContext() UIGraphicsEndImageContext() self.init(cgImage: image!.cgImage!) } }
Convert the UIImage
received from step 1 to CIImage
let ciimage = CIImage(image: image)
