Function

HarfBuzz-0.0 ▶ HarfBuzz ▶ draw_lineSince 14.2.0

  • Emits a tapered line segment as a filled trapezoid. w0 and w1 are the full stroke widths at the start and end points respectively; they may differ for a tapered stroke or match for a uniform one. Pass NaN for w1 to use w0 (uniform stroke) without repeating the value.

    With #HB_DRAW_LINE_CAP_SQUARE each endpoint is extended along the line direction by half its local stroke width, so four hb_draw_line() calls form a closed rectangle without gaps at the corners.
