# getData method

Uint8List getData()

Gets the raw data buffer of the image.

return Raw data buffer of the image. throws FaceException An error has occurred during Face Library execution.

## Implementation

    Uint8List getData() {
      Pointer<UnsignedChar> pData = nullptr;
      Pointer<Int> pDataSize = calloc();
      pDataSize[0] = -1;
      try {
        var err = faceSDK.id3FaceImage_GetData(_pHandle.value, pData, pDataSize);
        if (err == FaceError.insufficientBuffer.value) {
          pData = calloc.allocate(pDataSize.value);
          err = faceSDK.id3FaceImage_GetData(_pHandle.value, pData, pDataSize);
        }
        if (err != FaceError.success.value) {
          throw FaceException(err);
        }
        final vData = Uint8List.fromList(pData.cast<Uint8>().asTypedList(pDataSize.value));
        return vData;
      } finally {
        calloc.free(pData);
        calloc.free(pDataSize);
      }
    }
