Function: measurePx()

measurePx(raw, scale, fontSize, text, prof?): number

Defined in: core/src/measure/FontkitMeasureContext.ts:367

Pixel width of text under profile. Shared by the pretext measure context and ParagraphLayoutEngine's fragment measurement so line breaking and positioning never disagree.

• advance — Σ per-code-point advanceWidth, surrogate-aware, with the MISSING_GLYPH_FACTOR · fontSize estimate for absent glyphs.
• shape — fontkit layout() advance (kerning + ligatures). Missing glyphs there fall back to the same per-code-point estimate for the stretch that produced no advance, so the two profiles agree on un-shapeable text.
