Function

HarfBuzz-0.0 ▶ HarfBuzz ▶ ot_var_normalize_coordsSince 1.4.2

  • Normalizes the given design-space coordinates. The minimum and maximum values for the axis are mapped to the interval [-1,1], with the default axis value mapped to 0.

    The normalized values have 14 bits of fixed-point sub-integer precision as per OpenType specification.

    Any additional scaling defined in the face's avar table is also applied, as described at https://docs.microsoft.com/en-us/typography/opentype/spec/avar

    Note: coords_length must be the same as the number of axes in the face, as for example returned by hb_ot_var_get_axis_count(). Otherwise, the behavior is undefined.

    Parameters

    • face: face_t

      The HarfBuzz.face_t to work on

    • coords_length: number

      The length of the coordinate array

    • design_coords: number

      The design-space coordinates to normalize

    Returns number
