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 | NonereturnNonecCsx|dur||_ng|_d|_|dur:ddgdgddgdgddggdd}||vr3d |d }t||||_dSdS) N1:(... ... ...)->0z4:(00. 01. ...)->1z4:(... .0. .1.)->1z4:(... .0. ..1)->1z4:(... .1. .0.)->0z4:(... .1. ..0)->0)rz4:(.0. .1. ...)->1z4:(01. .1. ...)->1)corner dilation4 dilation8erosion4erosion8edgezUnknown pattern !)rlut Exception)selfrrknown_patternsmsgr!]/var/www/html/chefvision.cloud.itp360.com/venv/lib/python3.10/site-packages/PIL/ImageMorph.py__init__As" zLutBuilder.__init__ list[str]cCs|j|7_dSNr)rrr!r!r" add_patterns\szLutBuilder.add_patternscs.ddgdtfddttD|_dS)Nrrc3s |] }|@dkVqdS)rNr!).0imsymbolsr!r" bsz/LutBuilder.build_default_lut..) bytearrayrangeLUT_SIZErrr!r+r"build_default_lut_s"zLutBuilder.build_default_lutbytearray | NonecCs|jSr%rr2r!r!r"get_lutdszLutBuilder.get_lutpatternstr permutation list[int]cs(t|dksJdfdd|DS)zstring_permute takes a pattern and a permutation and returns the string permuted according to the permutation list. c3s|]}|VqdSr%r!)r)pr7r!r"r.lsz-LutBuilder._string_permute..)lenjoin)rr7r9r!r>r"_string_permutegszLutBuilder._string_permute basic_patternoptions basic_resultintlist[tuple[str, int]]c Cs||fg}d|vr%|dd}tdD]}|||ddt|fqd|vrCt|}|d|D]\}}|||t|fq3d|vrqt|}|d|D]\}}|d d d d d d }dt|}|||fqQ|S) zpattern_permute takes a basic pattern and its result and clones the pattern according to the modifications described in the $options parameter.
