DESCRIPTION

41       d.zoom allows the user to interactively adjust the settings of the cur‐
42       rent  geographic  region using a pointing device such as a mouse.  Like
43       g.region, d.zoom re-defines the  settings  of  the  geographic  region.
44       However,  d.zoom  allows the user to change the current region settings
45       interactively, by either outlining the  new  region  perimeter  with  a
46       mouse, unzoom or pan the region. The graphics display is updated by the
47       module.
48
49       After the user types the command d.zoom a mouse-button menu will appear
50       directing the user.
51
52       Additionally the region settings can be modified by running g.region.
53

NOTES

55       Although  it is not necessary that the user display a map in the active
56       display frame before running d.zoom, it is helpful to do this for  ref‐
57       erence.  Using  parameter  -f integrate a pan function, -h  facilitates
58       the use for handhelds.
