Struct LineMetrics

pub struct LineMetrics {
    pub ascent: f32,
    pub descent: f32,
    pub line_gap: f32,
    pub new_line_size: f32,
}

Available on crate feature dep_fontdue only.

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.

Trait Implementations

impl Clone for LineMetrics

fn clone(&self) -> LineMetrics

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for LineMetrics

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl PartialEq for LineMetrics

fn eq(&self, other: &LineMetrics) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
