Extra scale and vertical tweak to apply to all text of a certain font.

Fields

scale: f32

Scale the font’s glyphs by this much. this is only a visual effect and does not affect the text layout.

Default: 1.0 (no scaling).

y_offset_factor: f32

Shift font’s glyphs downwards by this fraction of the font size (in points). this is only a visual effect and does not affect the text layout.

Affects larger font sizes more.

A positive value shifts the text downwards. A negative value shifts it upwards.

Example value: -0.2.

y_offset: f32

Shift font’s glyphs downwards by this amount of logical points. this is only a visual effect and does not affect the text layout.

Affects all font sizes equally.

Example value: 2.0.

hinting: Option<bool>

Override the global font hinting setting for this specific font.

None means use the global setting in TextOptions::font_hinting.

hinting_target: HintingTarget

How to grid-fit the glyph outlines when hinting is enabled.

Has no effect when hinting is disabled (see Self::hinting).

subpixel_binning: Option<bool>

Override the global sub-pixel binning setting for this specific font.

None means use the global setting in TextOptions::subpixel_binning.

coords: VariationCoords

Override the font’s default variation coordinates for its axes (“wght”, etc.).

thin_space_width: f32

Width of a thin space (\u{2009}) and narrow no-break space (\u{202F}), as a fraction of the normal space width.

Thin space is often used as a thousands separator: 1 234 567.

Default: 0.5 (half a normal space).

tab_size: f32

Width of a tab character (\t), measured in number of space widths.

Default: 4.0.
