// Description:
//
// Class declaration of ossimU16ImageData.  Specialized image data object for
// unsigned short data with an 11 bit depth.
//
// NOTE:  This object is optimized for unsigned short data and assumes the
//        following:  null pixel value  = 0.0
//                    min  pixel value  = 1.0
//                    max  pixel value  = 2047.0  (2^11 - 1)
//
//        If you want anything else use the less efficient ossimImageData.
