## Implementation

    int getPixelDepth() {
      Pointer<Int> pPixelDepth = calloc();
      try {
        var err = faceSDK.id3FaceImage_GetPixelDepth(_pHandle.value, pPixelDepth);
        if (err != FaceError.success.value) {
          throw FaceException(err);
        }
        final vPixelDepth = pPixelDepth.value;
        return vPixelDepth;
      } finally {
        calloc.free(pPixelDepth);
      }
    }
