Implementations§

source§

impl AttrFontFeatures

source

pub fn as_ptr(&self) -> *mut PangoAttrFontFeatures

Return the inner pointer to the underlying C value.

source§

impl AttrFontFeatures

source

pub fn new(features: &str) -> Self

Create a new font features tag attribute.

You can use this attribute to select OpenType font features like small-caps, alternative glyphs, ligatures, etc. for fonts that support them.

features

a string with OpenType font features, with the syntax of the CSS font-feature-settings property

Returns

the newly allocated Attribute, which should be freed with Pango::Attribute::destroy()
