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() Núlist[str] | Noneú str | NoneÚNone)ÚpatternsÚop_nameÚreturncCsv|dk r||_ng|_d|_|dk rrddgdgddgdgddgdddgd œ}||krhd |d }t|ƒ‚|||_dS) Nz1:(... ... ...)->0z4:(00. 01. ...)->1z4:(... .0. .1.)->1z4:(... .0. ..1)->1z4:(... .1. .0.)->0z4:(... .1. ..0)->0z4:(.0. .1. ...)->1z4:(01. .1. ...)->1)ZcornerZ dilation4Z dilation8Zerosion4Zerosion8ZedgezUnknown pattern ú!)rÚlutÚ Exception)ÚselfrrZknown_patternsÚmsg©rú2/tmp/pip-unpacked-wheel-ciywl2yd/PIL/ImageMorph.pyÚ__init__As&ýú  zLutBuilder.__init__z list[str])rrcCs|j|7_dS©N©r)rrrrrÚ add_patterns\szLutBuilder.add_patterns)rcs.ddg‰d‰t‡‡fdd„ttƒDƒƒ|_dS)Nrréc3s|]}ˆ|ˆ@dkVqdS)rNr)Ú.0Úi©ÚmÚsymbolsrrÚ bsz/LutBuilder.build_default_lut..)Ú bytearrayÚrangeÚLUT_SIZEr©rrr"rÚbuild_default_lut_szLutBuilder.build_default_lutúbytearray | NonecCs|jSr©rr)rrrÚget_lutdszLutBuilder.get_lutÚstrz list[int])ÚpatternÚ permutationrcs(t|ƒdkst‚d ‡fdd„|Dƒ¡S)z„string_permute takes a pattern and a permutation and returns the string permuted according to the permutation list. é Úc3s|]}ˆ|VqdSrr)r Úp©r/rrr%lsz-LutBuilder._string_permute..)ÚlenÚAssertionErrorÚjoin)rr/r0rr4rÚ_string_permutegszLutBuilder._string_permuteÚintzlist[tuple[str, int]])Ú basic_patternÚoptionsÚ basic_resultrc Csæ||fg}d|krJ|dd}tdƒD]"}| | |ddt¡|f¡q&d|kr†t|ƒ}|d|…D]\}}| | |t¡|f¡qfd|krât|ƒ}|d|…D]>\}}| d d ¡ d d ¡ d d ¡}dt|ƒ}| ||f¡q¢|S) zÉpattern_permute takes a basic pattern and its result and clones the pattern according to the modifications described in the $options parameter.
