Tvg_Text_Metrics

Struct Tvg_Text_Metrics 

Source
#[repr(C)]
pub struct Tvg_Text_Metrics { pub ascent: f32, pub descent: f32, pub linegap: f32, pub advance: f32, }
Expand description

@brief Describes the font metrics of a text object.

Provides the basic vertical layout metrics used for text rendering, such as ascent, descent, and line spacing (linegap).

@see tvg_text_get_text_metrics() @note Experimental API

Fields§

§ascent: f32

< Distance from the baseline to the top of the highest glyph (usually positive).

§descent: f32

< Distance from the baseline to the bottom of the lowest glyph (usually negative, as in TTF).

§linegap: f32

< Additional spacing recommended between lines (leading).

§advance: f32

< The total vertical advance between lines of text: ascent - descent + linegap (i.e., ascent + |descent| + linegap when descent is negative).
