Description
-----------

This module plots the GMT logo on a map. By default, the GMT logo is 144 points (2 inches wide) and 72 points (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:

**-D**\ [**g**\|\ **j**\|\ **J**\|\ **n**\|\ **x**]\ *refpoint*\ **+w**\ *width*\ [**+j**\ *justify*]\ [**+o**\ *dx*\ [/*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 **+w**\ *width* to set the width of the GMT logo in plot coordinates
    (inches, cm, etc.).
    By default, the anchor point on the GMT logo 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 :doc:`text`).
    **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 GMT logo by *dx*/*dy* away from the *refpoint* point in
    the direction implied by *justify* (or the direction implied by **-Dj** or **-DJ**).

.. _-F:

**-F**\ [**+c**\ *clearances*][**+g**\ *fill*][**+i**\ [[*gap*/]\ *pen*]][**+p**\ [*pen*]][**+r**\ [*radius*]][**+s**\ [[*dx*/*dy*/][*shade*]]]
    Without further options, draws a rectangular border around the GMT logo using
    :term:`MAP_FRAME_PEN`; specify a different pen with **+p**\ *pen*.
    Add **+g**\ *fill* to fill the GMT logo box [no fill].
    Append **+c**\ *clearance* 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 2\ **p** and the :term:`MAP_DEFAULT_PEN`
    unless other values are specified. Append **+r** to draw rounded
    rectangular borders instead, with a 6\ **p** 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
    [4\ **p**/-4\ **p**] and *shade* sets the fill style to use for shading [gray50].

.. _-S:

**-S**\ [**l**\|\ **n**\|\ **u**]
    Control what is written beneath the map portion of the logo.
    Append **l** (or skip **-S** entirely) to plot the text label "The Generic Mapping Tools"
    beneath the logo.  Append **n** to skip the label placement, and append
    **u** to place the URL to the GMT site instead [plot the label].
