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 is 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 is their min 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 is 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 is their max value.

glyph_start: usize

The GlyphPosition index of the first glyph in the line.

glyph_end: usize

The GlyphPosition index of the last glyph in the line.
