This module plots the GMT logo on a map. By default, the GMT logo
is 2 inches wide and 1 inch high and will be positioned relative to the
current plot origin. Use various options to change this and to place a
transparent or opaque rectangular map panel behind the GMT logo.
- -D[g|j|J|n|x]refpoint+wwidth[+jjustify][+odx[/dy]]
- Sets reference point on the map for the image using one of four coordinate
systems: (1) Use -Dg for map (user) coordinates, (2) use -Dj
or -DJ for setting refpoint via a 2-char justification code
that refers to the (invisible) map domain rectangle, (3) use -Dn
for normalized (0-1) coordinates, or (4) use -Dx for plot
coordinates (inches, cm, etc.). All but -Dx requires both -R
and -J to be specified. Use +wwidth to set the width
of the GMT logo in plot coordinates (inches, cm, etc.). By default, the
anchor point on the scale is assumed to be the bottom left corner (BL),
but this can be changed by appending +j followed by a 2-char
justification code justify (see pstext). Note: If -Dj is
used then justify defaults to the same as refpoint, if
-DJ is used then justify defaults to the mirror opposite of
refpoint. Add +o to offset the color scale by
dx/dy away from the refpoint point in the direction
implied by justify (or the direction implied by -Dj or
-DJ).
- -F[+cclearances][+gfill][+i[[gap/]pen]][+p[pen]][+r[radius]][+s[[dx/dy/][shade]]]
- Without further options, draws a rectangular border around the GMT logo
using MAP_FRAME_PEN; specify a different pen with
+ppen. Add +gfill to fill the GMT logo box [no
fill]. Append +cclearance where clearance is either
gap, xgap/ygap, or
lgap/rgap/bgap/tgap where these items are
uniform, separate in x- and y-direction, or individual side spacings
between GMT logo and border. Append +i to draw a secondary, inner
border as well. We use a uniform gap between borders of 2p
and the MAP_DEFAULTS_PEN unless other values are specified. Append
+r to draw rounded rectangular borders instead, with a 6p
corner radius. You can override this radius by appending another value.
Finally, append +s to draw an offset background shaded region.
Here, dx/dy indicates the shift relative to the foreground
frame [4p/-4p] and shade sets the fill style to use
for shading [gray50].
For perspective view p, optionally append
/zmin/zmax. (more ...)

- -^ or just -
- Print a short message about the syntax of the command, then exits (NOTE:
on Windows just use -).
- -+ or just +
- Print an extensive usage (help) message, including the explanation of any
module-specific option (but not the GMT common options), then exits.
- -? or no arguments
- Print a complete usage (help) message, including the explanation of all
options, then exits.
To plot the GMT logo of a 2 inch width as a stand-alone plot,
use
gmt logo -P -Dx0/0+w2i > logo.ps
To append a GMT logo overlay in the upper right corner of the
current map, but scaled up to be 3 inches wide and offset by 0.1 inches from
the border, try
gmt logo -O -K -R -J -DjTR+o0.1i/0.1i+w3i >> bigmap.ps
