PANGO_RENDER_TYPE_WIN32

#define PANGO_RENDER_TYPE_WIN32 "PangoRenderWin32"

A string constant identifying the Win32 renderer. The associated quark (see g_quark_from_string()) is used to identify the renderer in pango_find_map().

PangoContext *      pango_win32_get_context             (void);

Retrieves a PangoContext appropriate for rendering with Windows fonts.

pango_win32_render ()

void                pango_win32_render                  (HDC hdc,
                                                         PangoFont *font,
                                                         PangoGlyphString *glyphs,

                                                         gint y);

Render a PangoGlyphString onto a Windows DC

pango_win32_render_transformed ()

void                pango_win32_render_transformed      (HDC hdc,
                                                         const PangoMatrix *matrix,

                                                         int y);

Renders a PangoGlyphString onto a windows DC, 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.

pango_win32_render_layout_line ()

void                pango_win32_render_layout_line      (HDC hdc,

                                                         int y);

Render a PangoLayoutLine onto a device context. For underlining to work property the text alignment of the DC should have TA_BASELINE and TA_LEFT.

pango_win32_render_layout ()

void                pango_win32_render_layout           (HDC hdc,
                                                         PangoLayout *layout,
                                                         int x,
                                                         int y);

Render a PangoLayoutLine onto an X drawable

PangoGlyph          pango_win32_get_unknown_glyph       (PangoFont *font,
                                                         gunichar wc);

Returns the index of a glyph suitable for drawing wc as an unknown character.

Use PANGO_GET_UNKNOWN_GLYPH() instead.

pango_win32_font_get_glyph_index ()

gint                pango_win32_font_get_glyph_index    (PangoFont *font,
                                                         gunichar wc);

Obtains the index of the glyph for wc in font, or 0, if not covered.

pango_win32_font_select_font ()

gboolean            pango_win32_font_select_font        (PangoFont *font,
                                                         HDC hdc);

Selects the font into the specified DC and changes the mapping mode and world transformation of the DC appropriately for the font. You may want to surround the use of this function with calls to SaveDC() and RestoreDC(). Call pango_win32_font_done_font() when you are done using the DC to release allocated resources.

See pango_win32_font_get_metrics_factor() for information about converting from the coordinate space used by this function into Pango units.

pango_win32_font_done_font ()

void                pango_win32_font_done_font          (PangoFont *font);

Releases any resources allocated by pango_win32_font_done_font()

pango_win32_font_get_metrics_factor ()

double              pango_win32_font_get_metrics_factor (PangoFont *font);

Returns the scale factor from logical units in the coordinate space used by pango_win32_font_select_font() to Pango units in user space.

pango_win32_get_debug_flag ()

gboolean            pango_win32_get_debug_flag          (void);

Returns whether debugging is turned on.

Obtains a handle to the Windows device context that is used by Pango.

PangoWin32FontCache

typedef struct _PangoWin32FontCache PangoWin32FontCache;

A PangoWin32FontCache caches HFONTs by their LOGFONT descriptions.

pango_win32_font_cache_new ()

PangoWin32FontCache * pango_win32_font_cache_new        (void);

Creates a font cache.

pango_win32_font_cache_free ()

void                pango_win32_font_cache_free         (PangoWin32FontCache *cache);

Frees a PangoWin32FontCache and all associated memory. All fonts loaded through this font cache will be freed along with the cache.

pango_win32_font_cache_load ()

HFONT               pango_win32_font_cache_load         (PangoWin32FontCache *cache,
                                                         const LOGFONTA *logfont);

Creates a HFONT from a LOGFONTA. The result may be newly loaded, or it may have been previously stored

pango_win32_font_cache_loadw ()

HFONT               pango_win32_font_cache_loadw        (PangoWin32FontCache *cache,
                                                         const LOGFONTW *logfont);

Creates a HFONT from a LOGFONTW. The result may be newly loaded, or it may have been previously stored

Since 1.16

pango_win32_font_cache_unload ()

void                pango_win32_font_cache_unload       (PangoWin32FontCache *cache,
                                                         HFONT hfont);

Frees a font structure previously loaded with pango_win32_font_cache_load().

pango_win32_font_map_for_display ()

PangoFontMap *      pango_win32_font_map_for_display    (void);

Returns a PangoWin32FontMap. Font maps are cached and should not be freed. If the font map is no longer needed, it can be released with pango_win32_shutdown_display().

pango_win32_shutdown_display ()

void                pango_win32_shutdown_display        (void);

Free cached resources.

pango_win32_font_map_get_font_cache ()

PangoWin32FontCache * pango_win32_font_map_get_font_cache
                                                        (PangoFontMap *font_map);

Obtains the font cache associated with the given font map.

pango_win32_font_logfont ()

LOGFONTA *          pango_win32_font_logfont            (PangoFont *font);

Determine the LOGFONTA struct for the specified font. Note that Pango internally uses LOGFONTW structs, so if converting the UTF-16 face name in the LOGFONTW struct to system codepage fails, the returned LOGFONTA will have an emppty face name. To get the LOGFONTW of a PangoFont, use pango_win32_font_logfontw(). It is recommended to do that always even if you don't expect to come across fonts with odd names.

pango_win32_font_logfontw ()

LOGFONTW *          pango_win32_font_logfontw           (PangoFont *font);

Determine the LOGFONTW struct for the specified font.

Since 1.16

pango_win32_font_description_from_logfont ()

PangoFontDescription * pango_win32_font_description_from_logfont

Creates a PangoFontDescription that matches the specified LOGFONTA.

The face name, italicness and weight fields in the LOGFONTA are used to set up the resulting PangoFontDescription. If the face name in the LOGFONTA contains non-ASCII characters the font is temporarily loaded (using CreateFontIndirect()) and an ASCII (usually English) name for it is looked up from the font name tables in the font data. If that doesn't work, the face name is converted from the system codepage to UTF-8 and that is used.

Since 1.12

pango_win32_font_description_from_logfontw ()

PangoFontDescription * pango_win32_font_description_from_logfontw
                                                        (const LOGFONTW *lfp);

Creates a PangoFontDescription that matches the specified LOGFONTW.

The face name, italicness and weight fields in the LOGFONTW are used to set up the resulting PangoFontDescription. If the face name in the LOGFONTW contains non-ASCII characters the font is temporarily loaded (using CreateFontIndirect()) and an ASCII (usually English) name for it is looked up from the font name tables in the font data. If that doesn't work, the face name is converted from UTF-16 to UTF-8 and that is used.
