The starting window is maximized to full screen and displays the global view of BORDEAUX (up to the Boulevards) with the main roads and direction of the traffic. The 'Global' Menu allows to return to this view (the Garonne below).

Click on a zone to display a corresponding detailed picture (the Garonne to the right, the North at the top). You get a display of the entire image with a zoom factor adapted to the window size (Zoom Mode).

By clicking on it, the picture is then displayed in its real size, the visible part matching the clicked zone (by using the ' True Size ' menu, the visible part corresponds to the centre of the image).

Quite the same functioning as the previous submenu, but this time, you must be first in 200% zoom to access a detailed image. This wide view allows an access to any suburb picture.

This is the larger sight of the urban area. The 200% view leads to the display of the Bypass view. Conversely, if you decrease the zoom factor from the Bypass view, it leads to the Urban Community image.

The 1st option allows to choose which one of these two views will be displayed at the start. This choice is registered in the file 'Bx.ini'.
The 2nd option allows to choose the default orientation (portrait or landscape) for printing a selected zone.
