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. )BytesIO)SimpleNamespace)Tag)sstruct) TTLibErrorTTLibFileIsCollectionErrorN) OrderedDictcHeZdZdZd dZdZeZdZdZdZ dZ dZ d Z y ) SFNTReaderc|ri|tura|d}|jdt|jd}|jd|dk(rddlm}t j|St j|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 O/var/www/html/bid-api/venv/lib/python3.12/site-packages/fontTools/ttLib/sfnt.pyrzSFNTReader.__new__sh C:%!WF KKNfkk!n-K KKNf$=~~k22~~c""c||_||_d|_d|_t|_|jj d|jjd|_|jj d|jdk(rt|j}|j}d|cxkr|ksntd|dz z||_ |jj |j||jjt}t|tk7r tdt!j"t$||n|jdk(rjd|_t&|_|jjt(}t|t(k7r td t!j"t*||nW|jjt}t|tk7r td t!j"t$||t-|j|_|jd vr td i}t/|j0D]G}|j } | j3|jt-| j4} | || <It7t9|j;d |_|jdk(rt?||_yy)Nrr sttcfz2specify a font number between 0 and %d (inclusive)'Not a Font Collection (not enough data)wOFFwoffz!Not a WOFF font (not enough data)z1Not a TrueType or OpenType font (not enough data))OTTOtruez1Not a TrueType or OpenType font (bad sfntVersion)c |djS)Nr)offset)is rz%SFNTReader.__init__..]s qt{{r)key) filecheckChecksumsflavor flavorDataSFNTDirectoryEntryDirectoryEntryrrr readTTCHeadernumFontsr offsetTablesfntDirectorySizelenrrunpacksfntDirectoryFormatWOFFDirectoryEntrywoffDirectorySizewoffDirectoryFormatrrange numTablesfromFiletagr sorteditemstablesWOFFFlavorData) selfr)r* fontNumberheaderr0datar?r&entryr<s r__init__zSFNTReader.__init__/sW , 0 q99>>!, q   w &"499-FH -X-0H!|%%DM IINN6--j9 :99>>"34D4y-- !JKK NN.d ;    ( DK"4D 99>>"34D4y-- !DEE NN.d ;99>>"34D4y-- !TUU NN.d ;t//0   #G GPQ Qt~~&A'')E NN499 %eii.CF3K ' "&=R"ST  ;;& ,T2DO !rc||jvSNr?rAr<s rhas_keyzSFNTReader.has_keycsdkk!!rc6|jjSrH)r?keysrAs rrMzSFNTReader.keyshs{{!!rcr|jt|}|j|j}|jrw|dk(rt |dddz|ddz}n t |}|jdkDr||j k(s Jd|z|S||j k7rtjd||S)zFetch the raw table data.headN rzbad checksum for '%s' table) r?rloadDatar)r* calcChecksumcheckSumlogwarning)rAr<rErDchecksums r __getitem__zSFNTReader.__getitem__ks CH%~~dii(   f}'Ra;(>bc(JK'-""Q&5>>1V3PSV3VV1 U^^+ 93? rc0|jt|=yrH)r?rrJs r __delitem__zSFNTReader.__delitem__}s KKC !rc8|jjyrH)r)closerNs rr^zSFNTReader.closes rct|jtr |jS|jj }|d=|jj |d<|jj |d<|S)Nr) _filename_filepos) isinstancer)r__dict__copynametellrAstates r __getstate__zSFNTReader.__getstate__sa dii )==  ""$ &M!YY^^k IINN,j rcd|vrJt|jdd|_|jj|jd|jj |y)Nr)r`rbra)openpopr)rrcupdatergs r __setstate__zSFNTReader.__setstate__sL  UYY{3T:DI IINN599Z0 1 U#rN)r) __name__ __module__ __qualname__rrFrK __contains__rMrZr\r^rirorrr r s7#"23h"L"$" $rr FrrQ 2d) rrwr rxrvrQ cd|cxkrdksntd|ztr|dk(rddlm}|||Sddlm}||t |S)aECompress 'data' to Zlib format.
