Function

HarfBuzz-0.0 ▶ HarfBuzz ▶ ot_math_get_glyph_variantsSince 1.3.3

  • Fetches the MathGlyphConstruction for the specified font, glyph index, and direction. The corresponding list of size variants is returned as a list of HarfBuzz.ot_math_glyph_variant_t structs.

    The direction parameter is only used to select between horizontal or vertical directions for the construction. Even though all HarfBuzz.direction_t values are accepted, only the result of #HB_DIRECTION_IS_HORIZONTAL is considered.

    Parameters

    • font: font_t

      HarfBuzz.font_t to work upon

    • glyph: number

      The index of the glyph to stretch

    • direction: direction_t

      The direction of the stretching (horizontal or vertical)

    • start_offset: number

      offset of the first variant to retrieve

    Returns [number, ot_math_glyph_variant_t[]]

    the total number of size variants available or zero
