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 | NonereturnNonec|||_ng|_d|_|;ddgdgddgdgddggdd}||vrd |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_patternsmsgs Q/var/www/api.educacionweb.es/myenv/lib/python3.11/site-packages/PIL/ImageMorph.py__init__zLutBuilder.__init__As  $DMMDM%)  /1EF2324HI1213GH  Nn,,3333nn$*73DMMM#   list[str]c&|xj|z c_dSNr)r!rs r$ add_patternszLutBuilder.add_patterns\s ! r&c|ddgdtfdttD|_dS)Nrrc36K|]}|zdkVdS)rN).0imsymbolss r$ z/LutBuilder.build_default_lut..bs0KKaWa!eq[1KKKKKKr&) bytearrayrangeLUT_SIZEr)r!r2r3s @@r$build_default_lutzLutBuilder.build_default_lut_sCa& KKKKK5??KKKKKr&bytearray | Nonec|jSr)r)r!s r$get_lutzLutBuilder.get_lutds xr&patternstr permutation list[int]cpt|dksJdfd|DS)zstring_permute takes a pattern and a permutation and returns the string permuted according to the permutation list. c3(K|] }|V dSr)r/)r0pr=s r$r4z-LutBuilder._string_permute..ls'77awqz777777r&)lenjoin)r!r=r?s ` r$_string_permutezLutBuilder._string_permutegsE;1$$$$ww7777;777777r& basic_patternoptions basic_resultintlist[tuple[str, int]]c||fg}d|vr\|dd}tdD]>}|||ddt|f?d|vrOt |}|d|D]5\}}|||t |f6d|vrt |}|d|D]l\}}|d d d d d d }dt|z }|||fm|S) zpattern_permute takes a basic pattern and its result and clones the pattern according to the modifications described in the $options parameter.
