The option 4 describes a series of symmetry operations (in this case a 4-rotation), the pattern is described by: - . or X - Ignore - 1 - Pixel is on - 0 - Pixel is off The result of the operation is described after "->" string. The default is to return the current pixel value, which is returned if no other match is found. Operations: - 4 - 4 way rotation - N - Negate - 1 - Dummy op for no other operation (an op must always be given) - M - Mirroring Example:: lb = LutBuilder(patterns = ["4:(... .1. 111)->1"]) lut = lb.build_lut() Npatternslist[str] | Noneop_name str | NonereturnNonecd|_|;ddgdgddgdgddggdd }||vrd |d }t||||_dS| ||_dSg|_dS) a :param patterns: A list of input patterns, or None. :param op_name: The name of a known pattern.
