	new Pango.Font () Create a new Pango.Font Create a new Pango.Font
	Pango.Font.description_from_string (String *str) : Pango.FontDescription Creates a new font description from a string representation in the form "[FAMILY-LIST] [STYLE-OPTIONS] [SIZE]", where FAMILY-LIST is a comma separated list of families optionally terminated by a comma, STYLE_OPTIONS is a whitespace separated list of words where each WORD describes one of style, variant, weight, stretch, or gravity, and SIZE is a decimal number (size in points) or optionally followed by the unit modifier "px" for absolute size. Creates a new font description from a string representation in the form "[FAMILY-LIST] [STYLE-OPTIONS] [SIZE]", where FAMILY-LIST is a comma separated list of families optionally terminated by a comma, STYLE_OPTIONS is a whitespace separated list of words where each WORD describes one of style, variant, weight, stretch, or gravity, and SIZE is a decimal number (size in points) or optionally followed by the unit modifier "px" for absolute size. Any one of the options may be absent. If FAMILY-LIST is absent, then the family_name field of the resulting font description will be initialized to NULL. If STYLE-OPTIONS is missing, then all style options will be set to the default values. If SIZE is missing, the size in the resulting font description will be set to 0. Parameters: String str* Required (not null) Returns: Pango.FontDescription	Pango.Font
	Pango.Font.descriptions_free (FontDescription *descs, Number n_descs) : none Frees an array of font descriptions. Frees an array of font descriptions. Parameters: Pango.FontDescription descs* Required (not null) Number n_descs Required (not null) Returns: none	Pango.Font
	describe () : Pango.FontDescription Returns a description of the font, with font size set in points. Returns a description of the font, with font size set in points. Use pango_font_describe_with_absolute_size() if you want the font size in device units. Returns: Pango.FontDescription	Pango.Font
	describe_with_absolute_size () : Pango.FontDescription Returns a description of the font, with absolute font size set (in device units). Returns a description of the font, with absolute font size set (in device units). Use pango_font_describe() if you want the font size in points. Returns: Pango.FontDescription	Pango.Font
	find_shaper (Language *language, Number ch) : Pango.EngineShape Finds the best matching shaper for a font for a particular language tag and character point. Finds the best matching shaper for a font for a particular language tag and character point. Parameters: Pango.Language language* Required (not null) Number ch Required (not null) Returns: Pango.EngineShape	Pango.Font
	get_coverage (Language *language) : Pango.Coverage Computes the coverage map for a given font and language tag. Computes the coverage map for a given font and language tag. Parameters: Pango.Language language* Required (not null) Returns: Pango.Coverage	Pango.Font
	get_font_map () : Pango.FontMap Gets the font map for which the font was created. Gets the font map for which the font was created. Note that the font maintains a weak reference to the font map, so if all references to font map are dropped, the font map will be finalized even if there are fonts created with the font map that are still alive. In that case this function will return NULL. It is the responsibility of the user to ensure that the font map is kept alive. In most uses this is not an issue as a PangoContext holds a reference to the font map. Returns: Pango.FontMap	Pango.Font
	get_glyph_extents (Number *glyph, Rectangle ink_rect, Rectangle logical_rect) : none Gets the logical and ink extents of a glyph within a font. Gets the logical and ink extents of a glyph within a font. The coordinate system for each rectangle has its origin at the base line and horizontal origin of the character with increasing coordinates extending to the right and down. The macros PANGO_ASCENT(), PANGO_DESCENT(), PANGO_LBEARING(), and PANGO_RBEARING() can be used to convert from the extents rectangle to more traditional font metrics. The units of the rectangles are in 1/PANGO_SCALE of a device unit. If font* is NULL, this function gracefully sets some sane values in the output variables and returns. Parameters: Number glyph Required (not null) Pango.Rectangle ink_rect Required (not null) or NULL to indicate that the result is not needed. Pango.Rectangle logical_rect Required (not null) or NULL to indicate that the result is not needed. Returns: none	Pango.Font
	get_metrics (Language *language) : Pango.FontMetrics Gets overall metric information for a font. Gets overall metric information for a font. Since the metrics may be substantially different for different scripts, a language tag can be provided to indicate that the metrics should be retrieved that correspond to the script(s) used by that language. If font* is NULL, this function gracefully sets some sane values in the output variables and returns. when finished using the object. Parameters: Pango.Language language Required (not null) for, or NULL to indicate to get the metrics for the entire font. Returns: Pango.FontMetrics	Pango.Font
