NAME
d.frame - Manages display frames on the user’s graphics monitor.
KEYWORDS
display, graphics, monitors, frame
SYNOPSIS
d.frame
d.frame --help
d.frame [-cepa] frame=name [at=bottom,top,left,right] [--overwrite]
[--help] [--verbose] [--quiet] [--ui]
Flags:
-c
Create a new frame if doesn’t exist and select
-e
Remove all frames, erase the screen and exit
-p
Print name of current frame and exit
-a
Print names of all frames including ’at’ position and exit
--overwrite
Allow output files to overwrite existing files
--help
Print usage summary
--verbose
Verbose module output
--quiet
Quiet module output
--ui
Force launching GUI dialog
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 moni-
tor 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 subse-
quent drawing will occur.
NOTES
The coordinates for the at option are stated in the form top,bot-
tom,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 an-
other, 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
