      try {
        var err = documentSDK.id3DocumentReader_ReadDocument(_pHandle.value, image.handle, pDocumentName ?? nullptr, readTexts.handle);
        if (err != DocumentError.success.value) {
          readTexts.dispose();
          throw DocumentException(err);
        }
        return readTexts;
      } finally {
        if (pDocumentName != null) {
          calloc.free(pDocumentName);
        }
