20 -e
22 Remove all frames, erase the screen and exit
23 -p

44 Parameters:
46 frame=name [required]
47 Frame to be selected or created (if -c flag is given)
48 at=bottom,top,left,right
50 Screen coordinates in percent where to place the frame (0,0 is
51 lower-left)
52 Implies only when -c or --overwrite flag is given
53 Options: 0-100
54
56 d.frame manages display frames on the current user’s graphics monitor.
57 Graphics are displayed in rectangular frames on whatever graphics moni‐
58 tor the user is currently directing GRASS display output to (defined by
59 d.mon module). These frames are created and managed with this module.
60 Note that GRASS frame contents are not retained when one frame covers
62 another. You cannot shuffle frames from top to bottom and then back
63 again. They simply define rectangular areas on the screen where subse‐
64 quent drawing will occur.
65
67 The coordinates for the at option are stated in the form top,bot‐
68 tom,left,right values are in percent. The upper-left corner of the
69 graphics monitor always is at location 0,0 while the monitor’s
70 lower-right corner is always at 100,100.
71 If the user has created multiple display frames that overlap one
73 another, whatever the user displays in the active frame will overwrite
74 those portions of the underlying frame where these frames overlap.
