Getting Started

This page present a simple program that will show a map of the topological map of the Mississippi river. The text of the program can be found inside the MilleFeuille source tree under progs/primer/millefeuille_primer.cpp.
After making the program, and starting the muralserver, just type millefeuille_primer in the progs/primer directory to see the map on the screen.

#include <stdlib.h>
#include <iostream.h>
#include <stdio.h>
#include "MilleFeuilleToolkit.H"
#include "Feuilles/Image.H"

main(int argc, char **argv)
{
  Mural *m;
  utilInit( argc, argv, NULL);

Initialises the utilities library that provide system resources.

  muralInit(argc, argv);

Initialises the mural server library.

  MilleFeuilleToolkit::init(argc,argv);

Initialises the MilleFeuille library.

  if ((muralConnect( &m, NULL )) != IWORK_OK)
    {
      utilSimpleError( "Couldn't connect to the mural server!" );
    }

Open a connection to the default mural. If the connection fails, bails out after printing an error message.

  try
    {
      CollagePtr background = MilleFeuilleToolkit::open_mural(m);

Create the root window for the hierarchy. open_mural also create a cursor that will track the motion of the mouse.

      Image mississippi("/n/radiance/mural/data/images/topomaps/Gorham.jpg");

Create an image Feuille using a picture of the Mississippi River at Gorham.

      mississippi.set_position(0,0);

Set the initial position of the image at (0,0).

      mississippi.set_size(m->width_pixels,
			   m->height_pixels);

Resize the image to cover the full mural.

      background->add_feuille(&mississippi);

Add the image to the background.

      background->post_redisplay();

Post a redisplay to show the changes on the screen.

      getchar();

Wait for the user to finish the program by pressing a key

    }
  catch (Exception &exception)
    {
      exception.print_error();
    }
  catch (...)
    {
      cerr << "Unknown exception occured." << endl;
    }
  return (0);
}
