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 a newly-allocated PangoFontDescription object.

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 a newly-allocated PangoFontDescription object.

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:

guint32 glyph Required (not null)

the glyph index

Pango.Rectangle ink_rect Required (not null)

rectangle used to store the extents of the glyph as drawn or NULL to indicate that the result is not needed.

Pango.Rectangle logical_rect Required (not null)

rectangle used to store the logical extents of the glyph or NULL to indicate that the result is not needed.

Returns:

none

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)

language tag used to determine which script to get the metrics for, or NULL to indicate to get the metrics for the entire font.

Returns:

Pango.FontMetrics a PangoFontMetrics object. The caller must call pango_font_metrics_unref()
