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() NcCsp|dur||_ng|_d|_|durlddgdgddgdgddggd¢dœ}||vrbtd |d ƒ‚|||_dS) Nú1:(... ... ...)->0z4:(00. 01. ...)->1z4:(... .0. .1.)->1z4:(... .0. ..1)->1z4:(... .1. .0.)->0z4:(... .1. ..0)->0)r z4:(.0. .1. ...)->1z4:(01. .1. ...)->1)ZcornerZ dilation4Z dilation8Zerosion4Zerosion8ÚedgezUnknown pattern ú!)ÚpatternsÚlutÚ Exception)ÚselfrÚop_nameZknown_patterns©rú_/home/droni/.local/share/virtualenvs/DPS-5Je3_V2c/lib/python3.9/site-packages/PIL/ImageMorph.pyÚ__init__@sú zLutBuilder.__init__cCs|j|7_dS©N©r)rrrrrÚ add_patternsXszLutBuilder.add_patternscs.ddg‰d‰t‡‡fdd„ttƒDƒƒ|_dS)Nrréc3s|]}ˆ|ˆ@dkVqdS)rNr)Ú.0Úi©ÚmÚsymbolsrrÚ ^óz/LutBuilder.build_default_lut..)Ú bytearrayÚrangeÚLUT_SIZEr©rrrrÚbuild_default_lut[szLutBuilder.build_default_lutcCs|jSr©rr&rrrÚget_lut`szLutBuilder.get_lutcs(t|ƒdksJ‚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)rÚp©Úpatternrrr!hr"z-LutBuilder._string_permute..)ÚlenÚjoin)rr.Z permutationrr-rÚ_string_permutecszLutBuilder._string_permutec Csæ||fg}d|vrJ|dd}tdƒD]"}| | |ddt¡|f¡q&d|vr†t|ƒ}|d|…D]\}}| | |t¡|f¡qfd|vrât|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.
