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
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).
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 [gray50O.
-O (more ...)
Append to existing PostScript plot.
-P (more ...)
Select "Portrait" plot orientation.
-R[unit]xmin/xmax/ymin/ymax[r] (more ...)
Specify the region of interest.
For perspective view p, optionally append /zmin/zmax. (more ...)
-U[just/dx/dy/][c|label] (more ...)
Draw GMT time stamp logo on plot.
-V[level] (more ...)
Select verbosity level [c].
-Y[a|c|f|r][y-shift[u]] (more ...)
Shift plot origin.
-ccopies (more ...)
Specify number of plot copies [Default is 1].
-t[transp] (more ...)
Set PDF transparency level in percent.
-^ or just -
Print a short message about the syntax of the command, then exits (NOTE: on Windows
use just -).
-+ 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 options, then
Print GMT version and exit.
Print full path to GMT share directory and exit.
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
