I suppose somewhere the function uses
uint8_t *FileHelper::GetImageData();
method.

uint8_t * is just for prototyping.
You have to cast the result according to the actual image type.
Is returned by
std::string GetPixelType();
method.
Possible values are :

* - "8U" unsigned 8 bit,
* - "8S" signed 8 bit,
* - "16U" unsigned 16 bit,
* - "16S" signed 16 bit,

HTH.
