pangoContextGetMetrics {RGtk2}R Documentation

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

object [PangoContext] a PangoContext
desc [PangoFontDescription] a PangoFontDescription structure
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 large enough to cover a range of languages will be returned. The process of determining such metrics is slow, so it is best to always make sure some real language tag will be used.

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.

Value

[PangoFontMetrics] a PangoFontMetrics object.
