#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.
| Returns : | the new PangoContext |
void pango_win32_render (HDC hdc,
PangoFont *font,
PangoGlyphString *glyphs,
gint x,
gint y);Render a PangoGlyphString onto a Windows DC
| hdc : | the device context |
| font : | the font in which to draw the string |
| glyphs : | the glyph string to draw |
| x : | the x position of start of string (in pixels) |
| y : | the y position of baseline (in pixels) |
void pango_win32_render_layout_line (HDC hdc,
PangoLayoutLine *line,
int x,
int y);Render a PangoLayoutLine onto a device context
| hdc : | HDC to use for uncolored drawing |
| line : | |
| x : | the x position of start of string (in pixels) |
| y : | the y position of baseline (in pixels) |
void pango_win32_render_layout (HDC hdc,
PangoLayout *layout,
int x,
int y);Render a PangoLayoutLine onto an X drawable
| hdc : | HDC to use for uncolored drawing |
| layout : | a PangoLayout |
| x : | the X position of the left of the layout (in pixels) |
| y : | the Y position of the top of the layout (in pixels) |
PangoGlyph pango_win32_get_unknown_glyph (PangoFont *font, gunichar wc);
Returns the index of a glyph suitable for drawing wc as an unknown character.
| font : | a PangoFont |
| wc : | the Unicode character for which a glyph is needed. |
| Returns : | a glyph index into font |
gint pango_win32_font_get_glyph_index
(PangoFont *font,
gunichar wc);Obtains the index of the glyph for wc in font.
| font : | a PangoFont. |
| wc : | a Unicode character. |
| Returns : | the glyph index for wc. |
struct PangoWin32FontCache;
A PangoWin32FontCache caches HFONTs by their LOGFONT descriptions.
PangoWin32FontCache* pango_win32_font_cache_new (void);
Creates a font cache.
| Returns : | The new font cache. This must be freed with 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.
| cache : |
HFONT pango_win32_font_cache_load (PangoWin32FontCache *cache, const LOGFONT *logfont);
Creates a HFONT from a LOGFONT. The result may be newly loaded, or it may have been previously stored
| cache : | |
| logfont : | a pointer to a LOGFONT structure describing the font to load. |
| Returns : | The font structure, or NULL if the font could not be loaded. In order to free this structure, you must call 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().
| cache : | |
| hfont : | the HFONT to unload |
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().
| Returns : | a PangoFontMap. |
PangoWin32FontCache* pango_win32_font_map_get_font_cache (PangoFontMap *font_map);
Obtains the font cache associated with the given font map.
| font_map : | a PangoWin32FontMap. |
| Returns : | the PangoWin32FontCache of font_map. |
