PangoFT2FontMap

typedef struct _PangoFT2FontMap PangoFT2FontMap;

The PangoFT2FontMap is the PangoFontMap implementation for FreeType fonts.

PANGO_RENDER_TYPE_FT2

#define PANGO_RENDER_TYPE_FT2 "PangoRenderFT2"

A string constant that was used to identify shape engines that work with the FreeType backend. See PANGO_RENDER_TYPE_FC for the replacement.

pango_ft2_font_map_new ()

PangoFontMap* pango_ft2_font_map_new        (void);

Create a new PangoFT2FontMap object; a fontmap is used to cache information about available fonts, and holds certain global parameters such as the resolution and the default substitute function (see pango_ft2_font_map_set_default_substitute()).

Since 1.2

pango_ft2_font_map_set_resolution ()

void        pango_ft2_font_map_set_resolution
                                            (PangoFT2FontMap *fontmap,
                                             double dpi_x,
                                             double dpi_y);

Sets the horizontal and vertical resolutions for the fontmap.

Since 1.2

pango_ft2_font_map_create_context ()

PangoContext* pango_ft2_font_map_create_context
                                            (PangoFT2FontMap *fontmap);

Create a PangoContext for the given fontmap.

Since 1.2

PangoFT2SubstituteFunc ()

void        (*PangoFT2SubstituteFunc)       (FcPattern *pattern,
                                             gpointer data);

Function type for doing final config tweaking on prepared FcPatterns.

pango_ft2_font_map_set_default_substitute ()

void        pango_ft2_font_map_set_default_substitute
                                            (PangoFT2FontMap *fontmap,
                                             PangoFT2SubstituteFunc func,
                                             gpointer data,
                                             GDestroyNotify notify);

Sets a function that will be called to do final configuration substitution on a FcPattern before it is used to load the font. This function can be used to do things like set hinting and antialiasing options.

Since 1.2

pango_ft2_font_map_substitute_changed ()

void        pango_ft2_font_map_substitute_changed
                                            (PangoFT2FontMap *fontmap);

Call this function any time the results of the default substitution function set with pango_ft2_font_map_set_default_substitute() change. That is, if your substitution function will return different results for the same input pattern, you must call this function.

Since 1.2

pango_ft2_get_context ()

PangoContext* pango_ft2_get_context         (double dpi_x,
                                             double dpi_y);

Retrieves a PangoContext for the default PangoFT2 fontmap (see pango_ft2_fontmap_get_for_display()) and sets the resolution for the default fontmap to dpi_x by dpi_y.

Use of this function is deprecated; see pango_ft2_fontmap_create_context() instead.

pango_ft2_render ()

void        pango_ft2_render                (FT_Bitmap *bitmap,

                                             int y);

Renders a PangoGlyphString onto a FreeType2 bitmap, possibly transforming the layed-out coordinates through a transformation matrix. Note that the transformation matrix for font is not changed, so to produce correct rendering results, the font must have been loaded using a PangoContext with an identical transformation matrix to that passed in to this function.

Since 1.6

pango_ft2_render_layout_line ()

void        pango_ft2_render_layout_line    (FT_Bitmap *bitmap,
                                             PangoLayoutLine *line,
                                             int x,

                                             PangoLayoutLine *line,
                                             int x,
                                             int y);

Render a PangoLayoutLine onto a FreeType2 bitmap, with he location specified in fixed-point Pango units rather than pixels. (Using this will avoid extra inaccuracies from rounding to integer pixels multiple times, even if the final glyph positions are integers.)

Since 1.6

pango_ft2_render_layout ()

void        pango_ft2_render_layout         (FT_Bitmap *bitmap,
                                             PangoLayout *layout,

                                             PangoLayout *layout,
                                             int x,
                                             int y);

Render a PangoLayout onto a FreeType2 bitmap, with he location specified in fixed-point Pango units rather than pixels. (Using this will avoid extra inaccuracies from rounding to integer pixels multiple times, even if the final glyph positions are integers.)

Since 1.6

pango_ft2_get_unknown_glyph ()

PangoGlyph  pango_ft2_get_unknown_glyph     (PangoFont *font);

Return the index of a glyph suitable for drawing unknown characters with font, or PANGO_GLYPH_EMPTY if no suitable glyph found.

If you want to draw an unknown-box for a character that is not covered by the font, use PANGO_GET_UNKNOWN_GLYPH() instead.

pango_ft2_font_get_kerning ()

int         pango_ft2_font_get_kerning      (PangoFont *font,
                                             PangoGlyph left,
                                             PangoGlyph right);

Retrieves kerning information for a combination of two glyphs.

Use pango_fc_font_kern_glyphs() instead.

pango_ft2_font_get_face ()

FT_Face     pango_ft2_font_get_face         (PangoFont *font);

Returns the native FreeType2 FT_Face structure used for this PangoFont. This may be useful if you want to use FreeType2 functions directly.

Use pango_fc_font_lock_face() instead; when you are done with a face from pango_fc_font_lock_face() you must call pango_fc_font_unlock_face().

pango_ft2_font_get_coverage ()

PangoCoverage* pango_ft2_font_get_coverage  (PangoFont *font,
                                             PangoLanguage *language);

Gets the PangoCoverage for a PangoFT2Font. Use pango_font_get_coverage() instead.

                                            (void);

Returns a PangoFT2FontMap. This font map is cached and should not be freed. If the font map is no longer needed, it can be released with pango_ft2_shutdown_display(). Use of the global PangoFT2 fontmap is deprecated; use pango_ft2_font_map_new() instead.

pango_ft2_shutdown_display ()

void        pango_ft2_shutdown_display      (void);

Free the global fontmap. (See pango_ft2_font_map_for_display()) Use of the global PangoFT2 fontmap is deprecated.
