DESCRIPTION
d.zoom allows the user to interactively adjust the settings
of the current geographic region using a pointing device such as
a mouse.
Like g.region,
d.zoom re-defines the settings of the geographic
region. However, d.zoom allows the user to change
the current region settings interactively, by either
outlining the new region perimeter with a mouse, unzoom
or pan the region. The graphics display is updated by the module.
After the user types the command d.zoom a mouse-button menu will appear
directing the user.
Additionally the region settings can be modified by
running g.region.
NOTES
Although it is not necessary that the user display a map in
the active display frame before running d.zoom, it
is helpful to do this for reference. Using parameter -f integrate a
pan function, -h facilitates the use for handhelds.
