pangoContextGetMetrics: pangoContextGetMetrics
Description
Get overall metric information for a 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.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
           pangoLanguageGetDefault) 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.
