Swift Gaussian模糊图像 [英] Swift Gaussian Blur an image

问题描述

我一直在开发应用程序已有一段时间了，很快就会完成。我使用 UIImage + ImageEffects.h 库模糊了一些图像，但现在我想切换到高斯模糊一个 UIImage

I've been developing an app for quite a while now and am soon to finish. I have been blurring some images using the UIImage+ImageEffects.h library, but now I want to switch to Gaussian blurring an UIImage

是否有任何库或类似内容可以让我在应用程序中高亮模糊图像？

Is there any library or something similar that would allow me to gaussian blur an image in my app?

推荐答案

我在我的应用程序中使用了以下内容。

I use following in my app.

 func applyBlurEffect(image: UIImage){
    var imageToBlur = CIImage(image: image)
    var blurfilter = CIFilter(name: "CIGaussianBlur")
    blurfilter.setValue(imageToBlur, forKey: "inputImage")
    var resultImage = blurfilter.valueForKey("outputImage") as CIImage
    var blurredImage = UIImage(CIImage: resultImage)
    self.blurImageView.image = blurredImage

  }
