* \brief Compose a 2D or 3D image and return a smart pointer to a SimpleITK
* image
*
* This filter is intended to interface SimpleITK to other image processing
* libraries and applications that may have their own representation of an
* image class. It creates a SimpleITK image which shares the bulk
* data buffer as what is set. SimpleITK will not responsible to
* delete the buffer afterwards, and it buffer must remain valid
* while in use.
