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. `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.
