swift - 应用 CIFilter 后图像旋转

Question

我正在将 CIFilter 应用于图像，但在应用滤镜后它会旋转。我找到了解决方案 here在 objective-c 中，我怎么能快速做到这一点？我的代码如下。

let originalImage = CIImage(image: cameraStill.image)

var filter = CIFilter(name: "CIPhotoEffect"+x)
filter.setDefaults()
filter.setValue(originalImage, forKey: kCIInputImageKey)

var outputImage = filter.outputImage
var newImage = UIImage(CIImage: outputImage)
v.setImage(newImage, forState: .Normal)

Answer 1

下面的代码对我来说效果很好:

    var image = UIImage(named: "Turtle")
    let ciImage = CIImage(image: image)
    let filter = CIFilter(name: "CISepiaTone")
    filter.setValue(ciImage, forKey: kCIInputImageKey)
    filter.setValue(1.5, forKey: kCIInputIntensityKey)
    let newImage = UIImage(CIImage: filter.outputImage)
    let imageView = UIImageView(image: newImage)
    self.view.addSubview(imageView)

告诉我你过得怎么样。
