|No-spaces|

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

Creates a basic or fancy basemap with axes, fill, and titles.
Several map projections are available, and the user may specify separate
tick-mark intervals for boundary annotation, ticking, and [optionally]
gridlines. A simple map scale or directional rose may also be plotted.
At least one of the options **-B**, **-L**, or **-T** must be specified.

Required Arguments
------------------

.. _-J:

.. |Add_-J| unicode:: 0x20 .. just an invisible code
.. include:: explain_-J.rst_

.. _-R:

.. |Add_-R| unicode:: 0x20 .. just an invisible code
.. include:: explain_-R.rst_

.. |Add_-Rz| unicode:: 0x20 .. just an invisible code
.. include:: explain_-Rz.rst_

Optional Arguments
------------------

.. _-A:

**-A**\ [*file*]
    No plotting is performed.  Instead, we determine the geographical coordinates of the polygon outline
    for the (possibly oblique) rectangular map domain.  The plot domain must be given via
    **-R** and **-J**, with no other options allowed. The sampling interval is controlled via
    :term:`MAP_LINE_STEP` parameter. The coordinates are written to *file* or to standard output if no file
    is specified.

.. _-B:

.. include:: explain_-B.rst_

.. _-F:

**-F**\ [**d**\|\ **l**\|\ **t**][**+c**\ *clearances*][**+g**\ *fill*][**+i**\ [[*gap*/]\ *pen*]][**+p**\ [*pen*]][**+r**\ [*radius*]][**+s**\ [[*dx*/*dy*/][*shade*]]]
    Without further options, draws a rectangular border around any map inset (**-D**\; classic mode only),
    map scale (**-L**) or map rose (**-T**) using
    :term:`MAP_FRAME_PEN`; specify a different pen with **+p**\ *pen*.
    Add **+g**\ *fill* to fill the 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 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].
    Used in combination with **-D**, **-L** or **-T**. To specify separate parameters
    for the various map features, append  **d**\|\ **l**\|\ **t** to **-F**
    to specify panel parameters for just that panel [Default uses the same panel
    parameters for all selected map features].
