Struct LineBox 

pub struct LineBox<T = F48Dot16> {
    pub ascender: T,
    pub descender: T,
    pub line_gap: T,
}

Ascender, descender and line gap from one table.

In font units unless a caller names another unit. The ascender is above the baseline and the descender below it, whatever sign a font stores them with.

Fields

ascender: T

Height of the line above the baseline. Never negative.

descender: T

Depth of the line below the baseline, as a negative value. Never positive.

line_gap: T

Extra space between the bottom of one line and the top of the next.

Implementations

impl<T> LineBox<T>

where T: Copy,

pub fn extents(&self) -> LineExtents<T>

Returns where this line begins and ends, without the gap after it.

Text stacks by the two ends; the gap separates one run of stacked text from the next.
