Overlapping components are first decomposed to simple contours, then merged. Currently this only works for fonts with 'glyf' or 'CFF ' tables. Raises NotImplementedError if 'glyf' or 'CFF ' tables are absent. Note that removing overlaps invalidates the hinting. By default we drop hinting from all glyphs whether or not overlaps are removed from a given one, as it would look weird if only some glyphs are left (un)hinted. Args: font: input TTFont object, modified in place. glyphNames: optional iterable of glyph names (str) to remove overlaps from. By default, all glyphs in the font are processed. removeHinting (bool): set to False to keep hinting for unmodified glyphs. ignoreErrors (bool): set to True to ignore errors while removing overlaps, thus keeping the tricky glyphs unchanged (fonttools/fonttools#2363). removeUnusedSubroutines (bool): set to False to keep unused subroutines in CFF table after removing overlaps. Default is to remove them if any glyphs are modified. rurzANo outline data found in the font: missing 'glyf' or 'CFF ' tableN)rrrsrrlrt)rrrsrrlrtr)NotImplementedError getGlyphOrder getGlyphSetrr)rrrsrlrtrrrrrrs2 cCsddl}|jdtd}|jdddd|jd d d d|jd d ddd|jdddd|jdddd|jdddd||}t|j }t||j pNd|j |j |j d| |jWddS1sjwYdS)z:Simplify glyphs in TTFont by merging overlapping contours.rNzfonttools ttLib.removeOverlaps) descriptioninputz INPUT.ttfzInput font file)metavarhelpoutputz OUTPUT.ttfzOutput font fileglyphsGLYPHS*z4Optional list of glyph names to remove overlaps from)rnargsrz--keep-hinting store_truez>Keep hinting for unmodified glyphs, default is to drop hinting)actionrz--ignore-errorszOignore errors while removing overlaps, thus keeping the tricky glyphs unchangedz--keep-unused-subroutineszrKeep unused subroutines in CFF table after removing overlaps, default is to remove them if any glyphs are modified)rrrsrlrtr)argparseArgumentParser__doc__ add_argument parse_argsrTTFontrrr keep_hinting ignore_errorskeep_unused_subroutinessaver)argsrparserrrrrrmainYsL "r__main__)T)NTFr")8rr<r^typingrrrrfontTools.cffLibrfontTools.ttLibrfontTools.ttLib.tablesrr fontTools.misc.psCharStringsr fontTools.misc.roundToolsr r fontTools.pens.ttGlyphPenr fontTools.pens.t2CharStringPenrr__all__ Exceptionr getLoggerr[str_TTGlyph_TTGlyphMappingrr GlyphComponentr'Glyphboolr?rDrMfloatrVrcrjtable__g_l_y_ftable__h_m_t_xrqrrrrrrrrrrrs                 '  # (  '  > /
