Declaration
var pixelBuffer: CVPixelBuffer? { get }Discussion
If this image was create using the init(cvPixelBuffer:) initializer, this property’s value is the CVPixelBuffer object that provides the image’s underlying image data. Do not modify the contents of this pixel buffer; doing so will cause undefined rendering results.
Otherwise, this property’s value is nil—in this case you can obtain a pixel buffer by rendering the image with the CIContext render(_:to:) method.
