以正确的尺寸打印NSImage

Question

我正在尝试打印NSImage，但是无法将其设置为适当的大小。我希望将NSImage作为4“ x6”照片打印在足够大的纸张上。这是我现在拥有的代码。

var printView = NSImageView(frame: NSRect(x: 0, y: 0, width: 72*4, height: 72*6))
var printInfo = NSPrintInfo()

printInfo.paperSize = NSSize(width: 72*4, height: 72*6)
printInfo.bottomMargin = 10
printInfo.topMargin = 10
printInfo.leftMargin = 10
printInfo.rightMargin = 10

printView.image = generateImage()
let printOp = NSPrintOperation(view: printView, printInfo: printInfo)
printOp.run()

Answer 1

这似乎解决了我的问题

var printView = NSImageView(frame: NSRect(x: 0, y: 0, width: 72*4, height: 72*6))
var printInfo = NSPrintInfo()

printInfo.bottomMargin = 0
printInfo.topMargin = 0
printInfo.leftMargin = 0
printInfo.rightMargin = 0

printView.image = generateImage()
let printOp = NSPrintOperation(view: printView, printInfo: printInfo)
printOp.run()
