}

Adjustment to the placement of a glyph as a result of kerning and placement of an attachment relative to a base glyph.

Variants

None

Distance(i32, i32)

Placement offset by distance delta.

Fields (delta x, delta y)

MarkAnchor(usize, Anchor, Anchor)

An anchored mark.

This is a mark where its anchor is aligned with the base glyph anchor.

Fields: (base glyph index in Vec<Info>, base glyph anchor, mark anchor)

MarkOverprint(usize)

An overprint mark.

This mark is shown at the same position as the base glyph.

Fields: (base glyph index in Vec<Info>)

CursiveAnchor(usize, bool, Anchor, Anchor)

Cursive anchored placement.

Fields:

• exit glyph index in Vec<Info>,
• RIGHT_TO_LEFT flag from lookup table,
• exit glyph anchor,
• entry glyph anchor
