* ImageTemplates.h - template class method definitions for classes derived
* from class ImageData and defined in ImageTemplates.C
*
* This file is included in the header files for the different image data
* types. ImageTemplates.C is included in the body files to define some
* methods that differ only in the raw image data type.
*
* See the man page ImageData(3) and the RTD User's Guide for a complete
* description of this class hierarchy.
