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.
