   Parameters:
       frame=name [required]
           Frame to be selected or created (if -c flag is given)

       at=bottom,top,left,right
           Screen coordinates in percent where to place the frame (0,0 is lower-left)

           Options: 0-100

DESCRIPTION

       d.frame manages display frames on  the  current  user’s  graphics  monitor.  Graphics  are  displayed  in
       rectangular  frames  on whatever graphics monitor the user is currently directing GRASS display output to
       (defined by d.mon module). These frames are created and managed with this module.

       Note that GRASS frame contents are not retained when one frame covers another. You cannot shuffle  frames
       from  top  to  bottom  and  then  back  again.  They  simply define rectangular areas on the screen where
       subsequent drawing will occur.

NOTES

       The coordinates for the at option are stated in the form top,bottom,left,right values are in percent. The
       upper-left  corner  of  the  graphics  monitor  always is at location 0,0 while the monitor’s lower-right
       corner is always at 100,100.

       If the user has created multiple display frames that overlap one another, whatever the user  displays  in
       the active frame will overwrite those portions of the underlying frame where these frames overlap.

EXAMPLE

       # start a new graphics monitor, the data will be rendered to
       # /tmp/map.png image output file of size 600x540px
       d.mon cairo out=/tmp/map.png width=600 height=540 --o
       # set up region
       g.region raster=elevation
       # remove all frames and erase the current graphics monitor
       d.frame -e
       # create a first frame and display ’landuse96_28m’ raster map including text label
       d.frame -c frame=first at=0,50,0,50
       d.rast landuse96_28m
       d.text text=’Landuse’ bgcolor=220:220:220 color=black size=6
       # create a second frame and display ’streams’ vector map
       d.frame -c frame=second at=0,50,50,100
       d.vect streams color=blue
       d.text text=’Streams’ bgcolor=220:220:220 color=black size=6
       # create a third frame and display ’elevation’ raster map including text label and scale
       d.frame -c frame=third at=50,100,0,50
       d.rast elevation
       d.text text=’Elevation’ bgcolor=220:220:220 color=black size=6
       d.barscale at=0,10 style=line bgcolor=none
       # create a fourth frame and display RGB composition map including text label
       d.frame -c frame=fourth at=50,100,50,100
       d.rgb red=lsat7_2002_30 green=lsat7_2002_20 blue=lsat7_2002_10
       d.text text=’RGB true colors’ bgcolor=220:220:220 color=black size=6
       # release the current graphics monitor
       d.mon -r
