Description

w:outline is a toggle property that applies an outline rendering effect to text in a run. Characters are rendered as hollow shapes — only the outer stroke of each glyph is drawn, without a filled interior.

It is defined in ECMA-376 Part 1 §17.3.2.23.

Notes

Legacy effect inherited from older Word formats. For richer outline effects in modern documents, use DrawingML text body properties.
May be combined with w:shadow for a classic outlined-with-shadow look.
