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.Usage
pangoContextGetMetrics(object, desc, language = NULL)
Arguments
language
[PangoLanguage
] language tag used to determine which script to get the metrics
for. NULL
means that the language tag from the context will
be used. If no language tag is set on the context, metrics
for the default language (as determined by

) will be returned. Details
The PangoFontDescription
is interpreted in the same way as
by pangoItemize
, 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.
