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. `NULL` means that the font description from the context will be used.
`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.

Value

[PangoFontMetrics] a PangoFontMetrics object.
