Posted 2021-05-19

    var newBuffer : CVPixelBuffer? = nil
    CVPixelBufferCreate(kCFAllocatorDefault, 227, 227, kCVPixelFormatType_32BGRA, nil, &newBuffer)

    guard let croppedBuffer = newBuffer else {
        print("___")
        return
    }
    
    let context = CIContext()
    context.render(cropedImage, to: croppedBuffer)
