-      CImgException is the base class of %CImg exceptions.
-      Exceptions are thrown by the %CImg Library when an error occured in a %CImg library function call.
-      CImgException is seldom thrown itself. Children classes that specify the kind of error encountered
-      are generally used instead. These sub-classes are :
-
-      - \b CImgInstanceException : Thrown when the instance associated to the called %CImg function is not
-      correctly defined. Generally, this exception is thrown when one tries to process \a empty images. The example
-      below will throw a \a CImgInstanceException.
-      \code
-      CImg<float> img;        // Construct an empty image.
-      img.blur(10);           // Try to blur the image.
-      \endcode
-
-      - \b CImgArgumentException : Thrown when one of the arguments given to the called %CImg function is not correct.
-      Generally, this exception is thrown when arguments passed to the function are outside an admissible range of values.
-      The example below will throw a \a CImgArgumentException.
-      \code
-      CImg<float> img(100,100,1,3);   // Define a 100x100 color image with float pixels.
-      img = 0;                     // Try to fill pixels from the 0 pointer (invalid argument to operator=() ).
-      \endcode
-
-      - \b CImgIOException : Thrown when an error occured when trying to load or save image files.
-      The example below will throw a \a CImgIOException.
-      \code
-      CImg<float> img("file_doesnt_exist.jpg");    // Try to load a file that doesn't exist.
-      \endcode
-
-      - \b CImgDisplayException : Thrown when an error occured when trying to display an image in a window.
-      This exception is thrown when image display request cannot be satisfied.
-
-      The parent class CImgException may be thrown itself when errors that cannot be classified in one of
-      the above type occur. It is recommended not to throw CImgExceptions yourself, since there are normally
-      reserved to %CImg Library functions.
-      \b CImgInstanceException, \b CImgArgumentException, \b CImgIOException and \b CImgDisplayException are simple
-      subclasses of CImgException and are thus not detailled more in this reference documentation.
-
-      \section ex2 Exception handling
-
-      When an error occurs, the %CImg Library first displays the error in a modal window.
-      Then, it throws an instance of the corresponding exception class, generally leading the program to stop
-      (this is the default behavior).
-      You can bypass this default behavior by handling the exceptions yourself,
-      using a code block <tt>try { ... } catch() { ... }</tt>.
-      In this case, you can avoid the apparition of the modal window, by
-      defining the environment variable <tt>cimg_debug</tt> to 0 before including the %CImg header file.
-      The example below shows how to cleanly handle %CImg Library exceptions :
-      \code
-      #define cimg_debug 0     // Disable modal window in CImg exceptions.
-      #define "CImg.h"
-      int main() {
-        try {
-          ...; // Here, do what you want.
-        }
-        catch (CImgInstanceException &e) {
-          std::fprintf(stderr,"CImg Library Error : %s",e.message);  // Display your own error message
-          ...                                                        // Do what you want now.
-        }
-      }
-      \endcode
-  **/
-  struct CImgException {
-    char message[1024]; //!< Message associated with the error that thrown the exception.
-    CImgException() { message[0]='\0'; }
-    CImgException(const char *format,...) { cimg_exception_err("CImgException",true); }
-  };
-
-  // The \ref CImgInstanceException class is used to throw an exception related
-  // to a non suitable instance encountered in a library function call.
-  struct CImgInstanceException : CImgException {
-    CImgInstanceException(const char *format,...) { cimg_exception_err("CImgInstanceException",true); }
-  };
-
-  // The \ref CImgArgumentException class is used to throw an exception related
-  // to invalid arguments encountered in a library function call.
-  struct CImgArgumentException : CImgException {
-    CImgArgumentException(const char *format,...) { cimg_exception_err("CImgArgumentException",true); }
-  };
-
-  // The \ref CImgIOException class is used to throw an exception related
-  // to Input/Output file problems encountered in a library function call.
-  struct CImgIOException : CImgException {
-    CImgIOException(const char *format,...) { cimg_exception_err("CImgIOException",true); }
-  };
-

-  // encountered in a library function call.

-  /**
-      Constructing a CImgStats instance from an image CImg<T> or a list CImgList<T>
-      will compute the minimum, maximum and average pixel values of the input object.
-      Optionally, the variance of the pixel values can be computed.
-      Coordinates of the pixels whose values are minimum and maximum are also stored.
-      The example below shows how to use CImgStats objects to retrieve simple statistics of an image :
-      \code
-      const CImg<float> img("my_image.jpg");                 // Read JPEG image file.
-      const CImgStats stats(img);                            // Compute basic statistics on the image.
-      stats.print("My statistics");                          // Display statistics.
-      std::printf("Max-Min = %lf",stats.max-stats.min);      // Compute the difference between extremum values.
-      \endcode
-
-      Note that statistics are computed by considering the set of \a scalar values of the image pixels.
-      No vector-valued statistics are computed.

-  //! Class representing an image (up to 4 dimensions wide), each pixel being of type \c T.
-  /**
-     This is the main class of the %CImg Library. It declares and constructs
-     an image, allows access to its pixel values, and is able to perform various image operations.
-
-     \par Image representation
-
-     A %CImg image is defined as an instance of the container \ref CImg<T>, which contains a regular grid of pixels,
-     each pixel value being of type \c T. The image grid can have up to 4 dimensions : width, height, depth
-     and number of channels.
-     Usually, the three first dimensions are used to describe spatial coordinates <tt>(x,y,z)</tt>, while the number of channels
-     is rather used as a vector-valued dimension (it may describe the R,G,B color channels for instance).
-     If you need a fifth dimension, you can use image lists \ref CImgList<T> rather than simple images \ref CImg<T>.
-
-     Thus, the \ref CImg<T> class is able to represent volumetric images of vector-valued pixels,
-     as well as images with less dimensions (1D scalar signal, 2D color images, ...).
-     Most member functions of the class CImg<T> are designed to handle this maximum case of (3+1) dimensions.
-
-     Concerning the pixel value type \c T :
-     fully supported template types are the basic C++ types : <tt>unsigned char, char, short, unsigned int, int,
-     unsigned long, long, float, double, ... </tt>.
-     Typically, fast image display can be done using <tt>CImg<unsigned char></tt> images,
-     while complex image processing algorithms may be rather coded using <tt>CImg<float></tt> or <tt>CImg<double></tt>
-     images that have floating-point pixel values. The default value for the template T is \c float.
-     Using your own template types may be possible. However, you will certainly have to define the complete set
-     of arithmetic and logical operators for your class.
-
-     \par Image structure
-
-     The \ref CImg<\c T> structure contains \a five fields :
-     - \ref width defines the number of \a columns of the image (size along the X-axis).
-     - \ref height defines the number of \a rows of the image (size along the Y-axis).
-     - \ref depth defines the number of \a slices of the image (size along the Z-axis).
-     - \ref dim defines the number of \a channels of the image (size along the V-axis).
-     - \ref data defines a \a pointer to the \a pixel \a data (of type \c T).
-
-     You can access these fields publicly although it is recommended to use the dedicated functions
-     dimx(), dimy(), dimz(), dimv() and ptr() to do so.
-     Image dimensions are not limited to a specific range (as long as you got enough available memory).
-     A value of \e 1 usually means that the corresponding dimension is \a flat.
-     If one of the dimensions is \e 0, or if the data pointer is null, the image is considered as \e empty.
-     Empty images should not contain any pixel data and thus, will not be processed by CImg member functions
-     (a CImgInstanceException will be thrown instead).
-     Pixel data are stored in memory, in a non interlaced mode (See \ref cimg_storage).
-
-     \par Image declaration and construction
-
-     Declaring an image can be done by using one of the several available constructors.
-     Here is a list of the most used :
-
-     - Construct images from arbitrary dimensions :
-         - <tt>CImg<char> img;</tt> declares an empty image.
-         - <tt>CImg<unsigned char> img(128,128);</tt> declares a 128x128 greyscale image with
-         \c unsigned \c char pixel values.
-         - <tt>CImg<double> img(3,3);</tt> declares a 3x3 matrix with \c double coefficients.
-         - <tt>CImg<unsigned char> img(256,256,1,3);</tt> declares a 256x256x1x3 (color) image
-         (colors are stored as an image with three channels).
-         - <tt>CImg<double> img(128,128,128);</tt> declares a 128x128x128 volumetric and greyscale image
-         (with \c double pixel values).
-         - <tt>CImg<> img(128,128,128,3);</tt> declares a 128x128x128 volumetric color image
-         (with \c float pixels, which is the default value of the template parameter \c T).
-         - \b Note : images pixels are <b>not automatically initialized to 0</b>. You may use the function \ref fill() to
-         do it, or use the specific constructor taking 5 parameters like this :
-         <tt>CImg<> img(128,128,128,3,0);</tt> declares a 128x128x128 volumetric color image with all pixel values to 0.
-
-     - Construct images from filenames :
-         - <tt>CImg<unsigned char> img("image.jpg");</tt> reads a JPEG color image from the file "image.jpg".
-         - <tt>CImg<float> img("analyze.hdr");</tt> reads a volumetric image (ANALYZE7.5 format) from the file "analyze.hdr".
-         - \b Note : You need to install <a href="http://www.imagemagick.org">ImageMagick</a>
-         to be able to read common compressed image formats (JPG,PNG,...) (See \ref cimg_files_io).
-
-     - Construct images from C-style arrays :
-         - <tt>CImg<int> img(data_buffer,256,256);</tt> constructs a 256x256 greyscale image from a \c int* buffer
-         \c data_buffer (of size 256x256=65536).
-         - <tt>CImg<unsigned char> img(data_buffer,256,256,1,3,false);</tt> constructs a 256x256 color image
-         from a \c unsigned \c char* buffer \c data_buffer (where R,G,B channels follow each others).
-         - <tt>CImg<unsigned char> img(data_buffer,256,256,1,3,true);</tt> constructs a 256x256 color image
-         from a \c unsigned \c char* buffer \c data_buffer (where R,G,B channels are multiplexed).
-

-
-     \par Most useful functions
-
-     The \ref CImg<T> class contains a lot of functions that operates on images.
-     Some of the most useful are :
-
-     - operator()(), operator[]() : allows to access or write pixel values.
-     - display() : displays the image in a new window.
-
-     \sa CImgList, CImgStats, CImgDisplay, CImgException.
