Metrics about a positioned line.

Fields

baseline_y: f32

The y coordinate of the baseline of this line, in pixels.

padding: f32

How much empty space is left at the end of the line before any alignment. If no max width is specified, f32::MAX is used.

max_ascent: f32

The highest point that any glyph in the font extends to above the baseline. Typically positive. If there are multiple styles on this line, this their max value.

min_descent: f32

The lowest point that any glyph in the font extends to below the baseline. Typically negative. If there are multiple styles on this line, this their max value.

max_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. If there are multiple styles on this line, this their max value.

max_new_line_size: f32

A precalculated value for the of the line depending. It’s calculated by: ascent - descent + line_gap. If there are multiple styles on this line, this their min value.

line_start: usize

The GlyphPosition index of the first glyph in the line.

line_end: usize

The GlyphPosition index of the last glyph in the line.
