Defines two public classes: - SFNTReader - SFNTWriter (Normally you don't have to use these classes explicitly; they are used automatically by ttLib.TTFont.) The reading and writing of sfnt files is separated in two distinct classes, since whenever the number of tables changes or whenever a table's length changes you need to rewrite the whole file anyway. ) annotations)KeysView)BytesIO)SimpleNamespace)Tag)sstruct) TTLibErrorTTLibFileIsCollectionErrorN) OrderedDictcTeZdZdZddZdd ZeZdd Zdd ZddZ ddZ dZ dZ dS) SFNTReaderc@|r|turz|d}|dt|d}|d|dkr ddlm}t |St |S)zmReturn an instance of the SFNTReader sub-class which is compatible with the input file type. rwOF2) WOFF2Reader)r seekrreadfontTools.ttLib.woff2robject__new__)clsargskwargsinfile sfntVersionrs y/home/lighthouse/badge-speaker-benchmark/.benchmark-venv-community/lib64/python3.11/site-packages/fontTools/ttLib/sfnt.pyrzSFNTReader.__new__ s  3C:%%!WF KKNNNfkk!nn--K KKNNNf$$======~~k222~~c"""rc>||_||_d|_d|_t|_|jd|jd|_|jd|jdkrt|j}|j }d|cxkr|ksntd|dz z||_ |j|j ||jt}t|tkrtdt!jt$||n|jdkrud|_t&|_|jt(}t|t(krtd t!jt*||na|jt}t|tkrtd t!jt$||t-|j|_|jd vrtd i}t/|jD]I}|} | |jt-| j} | || <Jt7t9|d |_|jdkrt?||_dSdS)Nrrsttcfz2specify a font number between 0 and %d (inclusive)'Not a Font Collection (not enough data)wOFFwoffz!Not a WOFF font (not enough data)z1Not a TrueType or OpenType font (not enough data))OTTOtruez1Not a TrueType or OpenType font (bad sfntVersion)c|djS)Nr )offset)is rz%SFNTReader.__init__.._s qt{r)key) filecheckChecksumsflavor flavorDataSFNTDirectoryEntryDirectoryEntryrrr readTTCHeadernumFontsr offsetTablesfntDirectorySizelenr runpacksfntDirectoryFormatWOFFDirectoryEntrywoffDirectorySizewoffDirectoryFormatrrange numTablesfromFiletagr sorteditemstablesWOFFFlavorData) selfr,r- fontNumberheaderr3datarBr)entryr?s r__init__zSFNTReader.__init__1s , 0 q9>>!,, q  w & &"49--FH ----X----0H!|%%DM INN6-j9 : : :9>>"344D4yy--- !JKKK N.d ; ; ; ;   ( ( DK"4D 9>>"344D4yy--- !DEEE N.d ; ; ; ;9>>"344D4yy--- !TUUU N.d ; ; ;t/00  #G G GPQQ Q,.t~&&  A''))E NN49 % % %ei..CF3KK!&=R=R"S"S"STT  ;& ,T22DOOO ! rr? str | bytesreturnboolc||jvSNrBrDr?s rhas_keyzSFNTReader.has_keyesdk!!r KeysView[Tag]c4|jSrN)rBkeysrDs rrTzSFNTReader.keysjs{!!!rbytesc|jt|}||j}|jr|dkr&t |dddz|ddz}nt |}|jdkr||jks Jd|zn&||jkrtd||S)zFetch the raw table data.headN r zbad checksum for '%s' table) rBrloadDatar,r- calcChecksumcheckSumlogwarning)rDr?rHrGchecksums r __getitem__zSFNTReader.__getitem__ms CHH%~~di((   @f}}'RaR;(>bcc(JKK'--"Q&&5>1113PSV3V1111U^++ 93??? rNonec0|jt|=dSrN)rBrrPs r __delitem__zSFNTReader.__delitem__s KC ! ! !rc8|jdSrN)r,closerUs rrgzSFNTReader.closes rct|jtr|jS|j}|d=|jj|d<|j|d<|S)Nr, _filename_filepos) isinstancer,r__dict__copynametellrDstates r __getstate__zSFNTReader.__getstate__sc di ) ) !=  ""$$ &M!Y^k INN,,j rcd|vrUt|dd|_|j|d|j|dS)Nr,rirbrj)openpopr,rrlupdaterps r __setstate__zSFNTReader.__setstate__sf   UYY{33T::DI INN599Z00 1 1 1 U#####rN)rr)r?rJrKrL)rKrR)r?rJrKrV)r?rJrKrc)rKrc) __name__ __module__ __qualname__rrIrQ __contains__rTrbrergrrrxrrr r s###"23232323h""""L""""$""""   $$$$$rr Fr rY 2d) r rrrr~rY cd|cxkrdksntd|ztr|dkrddlm}|||Sddlm}||t |S)aECompress 'data' to Zlib format.
