PangoFcFont is a base class for font implementation using the Fontconfig and FreeType libraries. It is used in the
Xft and FreeTypebackends shipped with Pango, but can also be used when creating new backends. Any backend deriving from this base class will take advantage of the wide range of shapers implemented using FreeType that come with Pango.
FT_Face
pango_fc_font_lock_face (PangoFcFont *font
);
pango_fc_font_lock_face
has been deprecated since version 1.44 and should not be used in newly-written code.
Use pango_font_get_hb_font()
instead
Gets the FreeType FT_Face
associated with a font,
This face will be kept around until you call
pango_fc_font_unlock_face()
.

pango_fc_font_unlock_face
has been deprecated since version 1.44 and should not be used in newly-written code.
Use pango_font_get_hb_font()
instead
Releases a font previously obtained with
pango_fc_font_lock_face()

gboolean pango_fc_font_has_char (PangoFcFont *font

pango_fc_font_has_char
has been deprecated since version 1.44 and should not be used in newly-written code.
Determines whether font
has a glyph for the codepoint wc
.
Since: 1.4
guint pango_fc_font_get_glyph (PangoFcFont *font
,gunichar wc
);
Gets the glyph index for a given Unicode character
for font
. If you only want to determine
whether the font has the glyph, use pango_fc_font_has_char()
.
Since: 1.4
PangoGlyph pango_fc_font_get_unknown_glyph (PangoFcFont *font

pango_fc_font_get_unknown_glyph
is deprecated and should not be used in newly-written code.
Returns the index of a glyph suitable for drawing wc
as an
unknown character.
Use PANGO_GET_UNKNOWN_GLYPH()
instead.

pango_fc_font_kern_glyphs
has been deprecated since version 1.32 and should not be used in newly-written code.
This function used to adjust each adjacent pair of glyphs
in glyphs
according to kerning information in font
.
Since 1.44, it does nothing.

PangoFcFont is a base class for font implementations
using the Fontconfig and FreeType libraries and is used in
conjunction with PangoFcFontMap. When deriving from this
class, you need to implement all of its virtual functions
other than shutdown()
along with the get_glyph_extents()
virtual function from PangoFont.
typedef struct { FT_Face (*lock_face) (PangoFcFont *font); void (*unlock_face) (PangoFcFont *font); gboolean (*has_char) (PangoFcFont *font, gunichar wc); guint (*get_glyph) (PangoFcFont *font, gunichar wc); PangoGlyph (*get_unknown_glyph) (PangoFcFont *font, gunichar wc); void (*shutdown) (PangoFcFont *font); } PangoFcFontClass;

Returns the FT_Face of the font and increases the reference count for the face by one. |

Decreases the reference count for the FT_Face of the font by one. When the count is zero, the PangoFcFont subclass is allowed to free the FT_Face. |
