TextDecoration

Remarks

Resolved except for the two autos, which only a run can settle. A thickness and an underline position are the face's to state — see DecorationMetrics — and a line may be composed of runs in more than one face, so the value that reaches here is either a length the author wrote or NaN meaning "ask the font". NaN rather than zero, for TextRun.Leading's reason: zero is a thickness somebody might mean.

⚠ Color is nullable and null means currentColor. CSS's initial value for text-decoration-color is currentColor, and resolving it to the text colour here rather than at the point of drawing would mean an element that sets only text-decoration-line carries a colour it never asked for — which the animator would then happily interpolate away from.

Fields and properties (6)

• public TextDecorationLine Lines

  Which lines to draw.

• public TextDecorationStyle Style

  Whether each is one bar or two.

• public Color4? Color

  What colour, or null for the text's own.

• public float Thickness

  How thick, in pixels, or NaN for the face's.

• public float Offset

  How much further down the underline sits, in pixels. Zero for auto.

• public bool IsNone

  Nothing to draw. The overwhelmingly common case, and the one that must cost nothing.
