Macos CVPixelBufferRef到NSImage
如何将CVPixelBufferRef转换为NSImage或CGImageRef?我需要能够在核心动画层中显示像素缓冲区的内容。要将缓冲区转换为图像,首先需要将缓冲区转换为Macos CVPixelBufferRef到NSImage,macos,cocoa,osx-lion,nsimage,Macos,Cocoa,Osx Lion,Nsimage,如何将CVPixelBufferRef转换为NSImage或CGImageRef?我需要能够在核心动画层中显示像素缓冲区的内容。要将缓冲区转换为图像,首先需要将缓冲区转换为CIImage,然后可以将其转换为NSImage let ciImage = CIImage(cvImageBuffer: pixelBuffer) let context = CIContext(options: nil) 从这里可以转到GCImage和NSImage: let width = CVPixelBuffer
CIImage
,然后可以将其转换为NSImage
let ciImage = CIImage(cvImageBuffer: pixelBuffer)
let context = CIContext(options: nil)
从这里可以转到GCImage
和NSImage
:
let width = CVPixelBufferGetWidth(pixelBuffer)
let height = CVPixelBufferGetHeight(pixelBuffer)
let cgImage = context.createCGImage(ciImage, from: CGRect(x: 0, y: 0, width: width, height: height))
let nsImage = NSImage(cgImage: cgImage, size: CGSize(width: width, height: height))
