我喜欢在xcode中使用swift 3拼接两个NSImages。 我能够使用“CIAdditionCompositing”）方法，它可以在彼此内部生成图片集。
现在我试图将两张图片并排放在垂直轴上。
使用UIImage的iphone IOS存在多个示例，这些示例不再适用。有没有人为Maci for NSimage提供一个例子？
这是我的CIAdditionCompositing的代码：
//------- combining images ----
// get images from internet
// webaddress
let filePath2 = "https://www.apple.com/ac/structured-data/images/open_graph_logo.png?201701131218"
let filePath1 = "https://staticdelivery.nexusmods.com/mods/110/images/74627-0-1459502036.jpg"
//create url paths
let url1 = NSURL(string: filePath1)
let url2 = NSURL(string: filePath2)
//retrieve images
let image1 = NSImage(byReferencing: url1! as URL)
let image2 = NSImage(byReferencing: url2! as URL)
// convert images
//read image 1
let imageData1 = image1.tiffRepresentation!
let ciImgage1 = CIImage(data: imageData1)
//read image 2
let imageData2 = image2.tiffRepresentation!
let ciImgage2 = CIImage(data: imageData2)
// filtersetting
let filter = CIFilter(name: "CIAdditionCompositing")!
filter.setDefaults()
filter.setValue(ciImgage2, forKey: "inputImage")
filter.setValue(ciImgage1, forKey: "inputBackgroundImage")
// collect result
let resultCIImage = filter.outputImage
// transfer back to nsimage
let rep = NSCIImageRep(ciImage: resultCIImage!)
let finalResult = NSImage(size: rep.size)
finalResult.addRepresentation(rep)
// display result image....
MyImage.image = finalResult
