<function name="pango_font_face_describe">

<description>

Returns the family, style, variant, weight and stretch of

a #PangoFontFace. The size field of the resulting font description

will be unset.

<function name="pango_layout_get_tabs">

<description>

Get the current #PangoTabArray used by this layout. If no

#PangoTabArray has been set, then the default tabs are in use

and an invalid instance is returned. Default tabs are every 8 spaces.

<return> a copy of the tabs for this layout.

<function name="pango_context_get_metrics">

<description>

Get overall metric information for a font particular font

description.  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.

The #PangoFontDescription is interpreted in the same way as

by pango_itemize(), and the family name may be a comma separated

list of figures. If characters from multiple of these families

would be used to render the string, then the returned fonts would

be a composite of the metrics for the fonts loaded for the

individual families.

<function name="pango_font_get_glyph_extents">

<description>

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.
