self.height = kwargs.get('height', 0)
        self.path = kwargs.get('path', '')

        self.transform = kwargs.get('transform', None)

        self.annotation_styles = kwargs.get('annotation_styles', {})

        self.colorspace = 'BGR'
        if 'colorspace' in kwargs:
            self.colorspace = kwargs['colorspace']
            if self.colorspace not in ('BGR', 'RGB'):
                raise Exception("Parameter colorspace must be either 'RGB' or 'BGR'")

        self.max_repeats = 0

        self.watchlist = WatchList()
