/**
* \brief Image
* \details This is the container for an Image in the general sense.
* From this container you should be able to request information like:
* - Origin
* - Dimension
* - PixelFormat
* ...
* But also to retrieve the image as a raw buffer (char *)
* Since we have to deal with both RAW data and JPEG stream (which
* internally encode all the above information) this API might seems
* redundant. One way to solve that would be to subclass Image
* with JPEGImage which would from the stream extract the header info
* and fill it to please Image...well except origin for instance
*
* Basically you can see it as a storage for the Pixel Data element (7fe0,0010).
*
* \warning This class does some heuristics to guess the Spacing but is not
* compatible with DICOM CP-586. In case of doubt use PixmapReader instead
*
* \see ImageReader PixmapReader
