    pub line_gap: f32,
    pub new_line_size: f32,
}

Expand description

Metrics associated with line positioning.

Fields

ascent: f32

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

descent: f32

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

line_gap: f32

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.

new_line_size: f32

A precalculated value for the height or width of the line depending on if the font is laid out horizontally or vertically. It’s calculated by: ascent - descent + line_gap.
