Struct rusttype::VMetrics

pub struct VMetrics {
    pub ascent: f32,
    pub descent: f32,
    pub line_gap: f32,
}

[−] Expand description

The “vertical metrics” of a font at a particular scale. This is useful for calculating the amount of vertical space to give a line of text, and for computing the vertical offset between successive lines.

Fields

ascent: f32

[−] Expand description

The highest point that any glyph in the font extends to above the baseline. Typically positive.

descent: f32

[−] Expand description

The lowest point that any glyph in the font extends to below the baseline. Typically negative.

line_gap: f32

[−] Expand description

The gap to leave between the descent of one line and the ascent of the next. This is of course only a guideline given by the font’s designers.
