Global font metrics.

Fields§

§units_per_em: u16

Number of font design units per em unit.

§glyph_count: u16

Number of glyphs in the font.

§is_monospace: bool

True if the font is monospace.

§has_vertical_metrics: bool

True if the font provides canonical vertical metrics.

§ascent: f32

Distance from the baseline to the top of the alignment box.

§descent: f32

Distance from the baseline to the bottom of the alignment box.

§leading: f32

Recommended additional spacing between lines.

§vertical_ascent: f32

Distance from the vertical center baseline to the right edge of the design space.

§vertical_descent: f32

Distance from the vertical center baseline to the left edge of the design space.

§vertical_leading: f32

Recommended additional spacing between columns.

§cap_height: f32

Distance from the baseline to the top of a typical English capital.

§x_height: f32

Distance from the baseline to the top of the lowercase “x” or similar character.

§average_width: f32

Average width of all non-zero characters in the font.

§max_width: f32

Maximum advance width of all characters in the font.

§underline_offset: f32

Recommended distance from the baseline to the top of an underline stroke.

§strikeout_offset: f32

Recommended distance from the baseline to the top of a strikeout stroke.

§stroke_size: f32

Recommended thickness of an underline or strikeout stroke.
