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. r\rlzANo outline data found in the font: missing 'glyf' or 'CFF ' tableN)rYrZrrVr[)rYrZrrVr[rk)NotImplementedErrorZ getGlyphOrderZ getGlyphSetrhrm)rYrZrVr[rkrrrrrs0cCsddl}|jdtd}|jdddd|jd d d d|jd d ddd|jdddd|jdddd|jdddd||}t|j>}t||j pd|j |j |j d| |jWdn1s0YdS)z:Simplify glyphs in TTFont by merging overlapping contours.rNzfonttools ttLib.removeOverlaps) descriptioninputz INPUT.ttfzInput font file)metavarhelpoutputz OUTPUT.ttfzOutput font fileglyphsZGLYPHS*z4Optional list of glyph names to remove overlaps from)rqnargsrrz--keep-hinting store_truez>Keep hinting for unmodified glyphs, default is to drop hinting)actionrrz--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)rYrZrVr[rk)argparseArgumentParser__doc__ add_argument parse_argsrTTFontrprrtZ keep_hinting ignore_errorsZkeep_unused_subroutinessavers)argsryparserrYrrrmainYsJ r__main__)T)NTF)N)8r{r2rItypingrrrrZfontTools.cffLibrZfontTools.ttLibrZfontTools.ttLib.tablesrr ZfontTools.misc.psCharStringsr ZfontTools.misc.roundToolsr r ZfontTools.pens.ttGlyphPenr ZfontTools.pens.t2CharStringPenrr__all__ Exceptionr getLoggerrFstrZ_TTGlyphZ_TTGlyphMappingrrZGlyphComponentr!ZGlyphboolr5r8r<floatrCrNrTZtable__g_l_y_fZtable__h_m_t_xrXr~rhrjrmrrrrrrrs              '  % *  '  > /
