FontMap

Provided Methods§

source

fn resolution(&self) -> f64

Gets the resolution for the fontmap.

See [methodPangoCairo.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.)
