Class

BoldModifier

Inherits:PooledAttributeModifier<ushort>

Applies bold styling to text using the CSS font-weight scale (1-1000).

Remarks

First parameter: CSS font-weight 1-1000; 0 or omitted = auto (max(700, baseWeight+300)). Second parameter — mode: f (<b=700,f>) keeps the current real face and supplies any missing weight synthetically (SDF dilate + advance correction); r (<b=700,r>) uses a real bold face only, staying at the natural weight when none matches. Default (no mode) prefers a real face — Font Family static cut or variable wght axis — and synthesizes only as a fallback. One buffer carries both: the top 2 bits select the mode, the low 10 bits the weight.
