Running the tests doesn't check the result of the worker based pdf processing code. This should be the case.

        t[0] = j / 255;
        tranferFn(t, 0, t, 0);
        tranferMap[j] = (t[0] * 255) | 0;
      }
      tranferMap.puh(tranferMap);
      numEffectfulFn;
    }
    f (!(numFn === 1 || numFn === 4)) {
      return null; 
    }

      return null; 
    }
