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) OrderedDictcR\rSrSrSrS SjrSr\rSrSr Sr Sr S r S r S rg ) SFNTReadercU(akU[LabUSnURS5 [URS55nURS5 US:XaSSKJn [ RU5$[ RU5$)z]Return an instance of the SFNTReader sub-class which is compatible with the input file type. rwOF2) WOFF2Reader)r seekrreadfontTools.ttLib.woff2robject__new__)clsargskwargsinfile sfntVersionrs W/srv/projetos/modelo_ml_acdoc/venv/lib/python3.13/site-packages/fontTools/ttLib/sfnt.pyrSFNTReader.__new__sh C:%!WF KKNfkk!n-K KKNf$=~~k22~~c""cXlX lSUlSUl[UlURR S5 URRS5UlURR S5 URS:Xa[UR5nURnSUs=::aU:dO [SUS- -5eXPl URR URU5 URR[5n[U5[:wa [S5e[ R""[$X`5 OURS:XakSUl[&UlURR[(5n[U5[(:wa [S 5e[ R""[*X`5 OXURR[5n[U5[:wa [S 5e[ R""[$X`5 [-UR5UlURS ;a [S 5e0n[/UR05HGnUR 5n U R3UR5 [-U R45n XU 'MI [7[9UR;5S S95UlURS:Xa[?U5Ulgg)Nrrsttcfz2specify a font number between 0 and %d (inclusive)'Not a Font Collection (not enough data)wOFFwoffz!Not a WOFF font (not enough data)z1Not a TrueType or OpenType font (not enough data))OTTOtruez1Not a TrueType or OpenType font (bad sfntVersion)c USR$)Nr)offset)is r%SFNTReader.__init__..]s qt{{r)key) filecheckChecksumsflavor flavorDataSFNTDirectoryEntryDirectoryEntryrrr readTTCHeadernumFontsr offsetTablesfntDirectorySizelenrrunpacksfntDirectoryFormatWOFFDirectoryEntrywoffDirectorySizewoffDirectoryFormatrrange numTablesfromFiletagr sorteditemstablesWOFFFlavorData) selfr,r- fontNumberheaderr3datarBr(entryr?s r__init__SFNTReader.__init__/sI , 0 q99>>!, q   w &"499-FH -X-0H!|%%M IINN6--j9 :99>>"34D4y-- !JKK NN. ;    ( DK"4D 99>>"34D4y-- !DEE NN. ;99>>"34D4y-- !TUU NN. ;t//0   #G GPQ Qt~~&A'')E NN499 %eii.C3K ' "&=R"ST  ;;& ,T2DO !rcXR;$NrBrDr?s rhas_keySFNTReader.has_keycskk!!rc6URR5$rL)rBkeysrDs rrRSFNTReader.keyshs{{!!rcUR[U5nURUR5nUR(azUS:Xa[ USSS-USS-5nO [ U5nURS:aXBR :Xd SU-5eU$XBR :wa[RSU5 U$)zFetch the raw table data.headN rzbad checksum for '%s' table) rBrloadDatar,r- calcChecksumcheckSumlogwarning)rDr?rHrGchecksums r __getitem__SFNTReader.__getitem__ks CH%~~dii(   f}'Ra;(>bc(JK'-""Q&>>1V3PSV3VV1 ^^+ 93? rc0UR[U5 grL)rBrrNs r __delitem__SFNTReader.__delitem__}s KKC !rc8URR5 grL)r,closerSs rrfSFNTReader.closes rc[UR[5(a UR$URR 5nUS URR US'URR 5US'U$)Nr, _filename_filepos) isinstancer,r__dict__copynametellrDstates r __getstate__SFNTReader.__getstate__sd dii ) )==  ""$ &M!YY^^k IINN,j rcSU;aJ[URS5S5UlURRURS55 URR U5 g)Nr,rirbrj)openpopr,rrlupdaterps r __setstate__SFNTReader.__setstate__sL  UYY{3T:DI IINN599Z0 1 U#r)r1r-r,r.r/r3rrBN)r)__name__ __module__ __qualname____firstlineno__rrIrO __contains__rRr`rcrfrrry__static_attributes__rrr r s7#"23h"L"$" $rr FrrW 2d) rrrrrrW cSUs=::aS::dO [SU-5e[(aUS:XaSSKJn U"X5$SSKJn U"U[ US9$)a1Compress 'data' to Zlib format.
