}
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.
