   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)
           Implies only when -c or --overwrite flag is given
           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
       # order: bottom,top,left,right - in percent
       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
