• #get_glyph(fcfont, wc) ⇒ Pango::Glyph

  Generates a PangoGlyph for the given Unicode point using the custom decoder.

Instance Method Details

#get_charset(fcfont) ⇒ fontconfig::CharSet

Generates an FcCharSet of supported characters for the fcfont given.

The returned FcCharSet will be a reference to an internal value stored by the PangoFcDecoder and must not be modified or freed.

Parameters:

• fcfont (PangoFc::Font) —

  the PangoFcFont to query.

Returns:

• (fontconfig::CharSet) —

  the FcCharset for fcfont; must not be modified or freed.

#get_glyph(fcfont, wc) ⇒ Pango::Glyph

Generates a PangoGlyph for the given Unicode point using the custom decoder.

For complex scripts where there can be multiple glyphs for a single character, the decoder will return whatever glyph is most convenient for it. (Usually whatever glyph is directly in the fonts character map table.) covered by the font.

Parameters:

• fcfont (PangoFc::Font) —

  a PangoFcFont to query.

• wc (Integer) —

  the Unicode code point to convert to a single PangoGlyph.

Returns:

• (Pango::Glyph) —

  the glyph index, or 0 if the glyph isn't
