Fonts
Structures representing abstract fonts.
Pango supports a flexible architecture where a
particular rendering architecture can supply an
implementation of fonts. The #PangoFont structure
represents an abstract rendering-system-indepent font.
Pango provides routines to list available fonts, and
to load a font of a given description.
The #PangoFontDescription structure represents the description
of an ideal font. These structures are used both to list
what fonts are available on the system and also for specifying
the characteristics of a font to load.
The GObject type for #PangoFontDescription.
@PANGO_STYLE_NORMAL:
@PANGO_STYLE_OBLIQUE:
@PANGO_STYLE_ITALIC:
The GObject type for #PangoStyle.
An enumeration specifying the weight (boldness) of a font. This is a numerical
value ranging from 100 to 900, but there are some predefined values:
@PANGO_WEIGHT_ULTRALIGHT: the ultralight weight (= 200)
@PANGO_WEIGHT_LIGHT: the light weight (=300)
@PANGO_WEIGHT_NORMAL: the default weight (= 400)
@PANGO_WEIGHT_BOLD: the bold weight (= 700)
@PANGO_WEIGHT_ULTRABOLD: the ultrabold weight (= 800)
@PANGO_WEIGHT_HEAVY: the heavy weight (= 900)
The GObject type for #PangoWeight.
An enumeration specifying capitalization variant of the font.
@PANGO_VARIANT_NORMAL: A normal font.
@PANGO_VARIANT_SMALL_CAPS: A font with the lower case characters
replaced by smaller variants of the capital characters.
The GObject type for #PangoVariant.
An enumeration specifying the width of the font relative to other designs
within a family.
@PANGO_STRETCH_ULTRA_CONDENSED:
@PANGO_STRETCH_EXTRA_CONDENSED:
@PANGO_STRETCH_CONDENSED:
@PANGO_STRETCH_SEMI_CONDENSED:
@PANGO_STRETCH_NORMAL: the normal width
@PANGO_STRETCH_SEMI_EXPANDED:
@PANGO_STRETCH_EXPANDED:
@PANGO_STRETCH_EXTRA_EXPANDED:
@PANGO_STRETCH_ULTRA_EXPANDED:
The GObject type for #PangoStretch.
The bits in a #PangoFontMask correspond to fields in a
#PangoFontDescription that have been set.
@PANGO_FONT_MASK_FAMILY: the font family is specified.
@PANGO_FONT_MASK_STYLE: the font style is specified.
@PANGO_FONT_MASK_VARIANT: the font variant is specified.
@PANGO_FONT_MASK_WEIGHT: the font weight is specified.
@PANGO_FONT_MASK_STRETCH: the font stretch is specified.
@PANGO_FONT_MASK_SIZE: the font size is specified.
The GObject type for #PangoFontMask.

The #PangoFont structure is used to represent
a font in a rendering-system-independent matter.
To create an implementation of a #PangoFont,
the rendering-system specific code should malloc
a larger structure that contains a nested
#PangoFont, fill in the klass member of
the nested #PangoFont with a pointer to
a appropriate #PangoFontClass, then call
pango_font_init() on the structure.
The #PangoFont structure contains one member
which the implementation fills in:
The GObject type for #PangoFont.
Casts a #GObject to a #PangoFont.
@object: a #GObject.
Returns %TRUE if @object is a #PangoFont.
@object: a #GObject.

The #PangoFontFamily structure is used to represent a family of related
font faces. The faces in a family share a common design, but differ in
slant, weight, width and other aspects.
The GObject type for #PangoFontFamily.
Casts a #GObject to a #PangoFontFamily.
@object: a #GObject.
Returns %TRUE if @object is a #PangoFontFamily.
@object: a #GObject.
@family:
@Returns:
@family:

@n_faces:
The #PangoFontFace structure is used to represent a group of fonts with
the same family, slant, weight, width, but varying sizes.
The GObject type for #PangoFontFace.
Casts a #GObject to a #PangoFontFace.
@object: a #GObject.
Returns %TRUE if @object is a #PangoFontFace.
@object: a #GObject.

@Returns:
The #PangoFontMap represents the set of fonts available for a
particular rendering system. This is a virtual object with
implementations being specific to particular rendering systems. To
create an implementation of a #PangoFontMap, the rendering-system
specific code should malloc a larger structure that contains a nested
#PangoFontMap, fill in the klass member of the nested #PangoFontMap with a
pointer to a appropriate #PangoFontMapClass, then call
pango_font_map_init() on the structure.
The #PangoFont structure contains one member which the implementation fills in:
The GObject type for #PangoFontMap.
Casts a #GObject to a #PangoFontMap.
@object: a #GObject.
Returns %TRUE if @object is a #PangoFontMap.
@object: a #GObject.
The #PangoFontMapClass structure holds the virtual functions for
a particular #PangoFontMap implementation.
@parent_class:
@load_font: a function to load a font with a given description. See
pango_font_map_load_font()
@list_families: A function to list available font families. See
pango_font_map_list_families().
@load_fontset:
@_pango_reserved1:
@_pango_reserved2:
@_pango_reserved3:
