Should add scale

    func toNativeImage(size: Size, _ scale: CGFloat = UIScreen.main.scale, layout: ContentLayout = .of()) -> MImage {
        let renderer = RenderUtils.createNodeRenderer(self, view: nil)
        let rect = size.rect()

        MGraphicsBeginImageContextWithOptions(size.toCG(), false, scale)
        let ctx = MGraphicsGetCurrentContext()!
        ctx.clear(rect.toCG())

        let transform = LayoutHelper.calcTransform(self, layout, size)
        ctx.concatenate(transform.toCG())
        renderer.render(in: ctx, force: false, opacity: self.opacity)

        let img = MGraphicsGetImageFromCurrentImageContext()
        MGraphicsEndImageContext()
        return img!
    }
