       Note: No space is allowed between the option flag and the associated arguments.

DESCRIPTION

       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.

REQUIRED ARGUMENTS

       None.

OPTIONAL ARGUMENTS

       -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
              [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].

       -X[a|c|f|r][x-shift[u]]

       -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 exits.

       --version
              Print GMT version and exit.

       --show-datadir
              Print full path to GMT share directory and exit.

EXAMPLES

       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
