Expand description

Trait containing all FontMap methods.

§Implementors

FontMap

Provided Methods§

Source

fn resolution(&self) -> f64

Gets the resolution for the fontmap.

See set_resolution().

§Returns

the resolution in “dots per inch”

Source

fn set_resolution(&self, dpi: f64)

Sets the resolution for the fontmap.

This is a scale factor between points specified in a PangoFontDescription and Cairo units. The default value is 96, meaning that a 10 point font will be 13 units high. (10 * 96. / 72. = 13.3).

§dpi

the resolution in “dots per inch”. (Physical inches aren’t actually involved; the terminology is conventional.)

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
