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() Nc|||_ng|_d|_|3ddgdgddgdgddggdd}||vrd |d }t||||_yy) 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 !)patternslut Exception)selfrop_nameknown_patternsmsgs L/var/www/urcfiles/bundle/venv/lib/python3.12/site-packages/PIL/ImageMorph.py__init__zLutBuilder.__init__As  $DMDM%)  /1EF2324HI1213GH Nn,( 3n$*73DM# c.|xj|z c_yNr)rrs r add_patternszLutBuilder.add_patterns\s ! r"cbddgdtfdttD|_y)Nrrc34K|]}|zdkDyw)rN).0imsymbolss r z/LutBuilder.build_default_lut..bsK?aWa!eq[1?s) bytearrayrangeLUT_SIZEr)rr-r.s @@r build_default_lutzLutBuilder.build_default_lut_s'a& K5?KKr"c|jSr$r)rs r get_lutzLutBuilder.get_lutds xxr"cXt|dk(sJdjfd|DS)zstring_permute takes a pattern and a permutation and returns the string permuted according to the permutation list. c3(K|] }| ywr$r*)r+ppatterns r r/z-LutBuilder._string_permute..ls7;awqz;s)lenjoin)rr< permutations ` r _string_permutezLutBuilder._string_permutegs-;1$$$ww7;777r"c||fg}d|vrE|dd}tdD]/}|j|j|ddt|f1d|vr?t |}|d|D],\}}|j|j|t |f.d|vrkt |}|d|D]X\}}|j d d j d d j d d }dt|z }|j||fZ|S) zpattern_permute takes a basic pattern and its result and clones the pattern according to the modifications described in the $options parameter.
