      descent = 0;
    }
    const vPadding = defaultPadding + Math.abs(descent) * fontSize;
    const alignment = this.data.textAlignment;
    if (this.data.multiLine) {
      return this._getMultilineAppearance(
        defaultAppearance,
        value,

      );
    }
    
    const encodedString = font.encodeString(value).join("");
    if (this.data.comb) {
      return this._getCombAppearance(
        defaultAppearance,
        font,
        encodedString,
