CVPixelBufferRef to NSImage
原标题:CVPixelBufferRef to NSImage

我怎么能够把CVPixelBufferRef转换到NSImage或CGImageRef? 我需要能够在一个核心的表层展示六氯缓冲器的内容。

问题回答

为了将缓冲转化为图像,你需要首先将缓冲转换为,然后可以转换为。 NSImage

let ciImage = CIImage(cvImageBuffer: pixelBuffer)

let context = CIContext(options: nil)

从这里看,你可以去到双轨。 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))
