Synopsis¶
gmtlogo [ -D[g|j|J|n|x]refpoint+wwidth[+jjustify][+odx[/dy]] ] [ -F[+cclearances][+gfill][+i[[gap/]pen]][+p[pen]][+r[radius]][+s[[dx/dy/][shade]]] ] [ -Jparameters ] [ -Jz|Zparameters ] [ -K ] [ -O ] [ -P ] [ -Rwest/east/south/north[/zmin/zmax][+r] ] [ -U[stamp] ] [ -V[level] ] [ -Xx_offset ] [ -Yy_offset ] [ -ttransp ]
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 [gray50].
- -O (more …)
- Append to existing PostScript plot.

- -^ 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.
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
