; Provides a simple wrapper to the MAP_CONTINENTS command in IDL that can be used
; to draw map continental outlines in a device and color independent way with
; Coyote Graphics programs.

; Provides a simple wrapper to the MAP_CONTINENTS command in IDL that can be used
; to draw map continental outlines in a device and color independent way with
; Coyote Graphics programs.
;
; :Categories:
; Graphics, Map Projections
;
; :Examples:
; To display a map of Cuba and Haiti::
; cgMap_Set, /Mercator, Limit=[5.0, -95, 35.0, -55.0]
; cgMap_Continents, Background='dodger blue', /Continents, /Fill, Color='tan'
; cgMap_Continents, /Countries, /USA, Color='navy', /Continents
;
; :Keywords:
; addcmd: in, optional, type=boolean, default=0
; If this keyword is set, the object is added to the resizeable graphics
; window, cgWindow. Note that a map projection command must be
; added to the window before this command is added to be effective.
; background: in, optional, type=string
; The name of the background color. A polygon of this color is drawn
; in the map space set up by the map projection before continents and
; other items are drawn.
; coasts: in, optional, type=boolean, default=0
; Set this keyword if you want coasts to be drawn. This keyword is ignored if using FILENAME.
; color: in, optional, type=string, default='opposite'
; The name of the drawing color for the program.
; continents: in, optional, type=boolean
; Set this keyword if you want continental outlines to be drawn. This will be
; set automatically if COASTS, COUNTRIES, RIVERS, and USA keywords are all set
; to zero. This keyword is ignored if using FILENAME.
; countries: in, optional, type=boolean, default=0
; Set this keyword to draw political boundaries.
; fill_continents: in, optional, type=boolean, default=0
; Set this keyword to draw filled polygons rather than outlines. If the value is
; 2, the continents are filled with lines rather than colors.
; hires: in, optional, type=boolean, default=0
; Set this keyword to use the high-resolution data supplied with IDL for MAP_CONTINENTS.
; This keyword is ignored if using FILENAME.
; limits: in, optional, type=fltarr(4)
; Set to a four-element vector, [Latmin, LonMin, LatMax, LonMax] that describes the
; limit rectangle. Only plot line segments that pass through this rectangle.
; linestyle: in, optional, type=integer, default=0
; Set to the type of linestyle in drawing outlines. Set solid lines by default.
; map_structure: in, optional, type=struct/object
; Set this keyword to a map structure as returned by Map_Proj_Init or to a map
; coordinate object (i.e., cgMap) from which a map structure can be obtained.
; mlinestyle:
; This keyword depreciated in favor of LINESTYLE keyword.
; mlinethick:
; This keyword depreciated in favor of THICK keyword.
; orientation: in, optional, type=float, default=0.0
; Set this keyword to the counterclockwise angle in degrees from horizontal that
; the line fill should be drawn. Only applies if the FILL_CONTINENTS keyword is 2.
; outline: in, optional, type=boolean, default=1
; Draw outlines of coastlines (really just sets the `COASTS` keyword). The `COASTS`
; keyword overrides this setting.
; rivers: in, optional, type=boolean, default=0
; Set this keyword if you wish to draw rivers. This keyword is ignored if using FILENAME.
; spacing: in, optional, type=float, default=0.5
; Set this keyword to the spacing, in centimeters, for a line fill. This keyword only has
; effect if the FILL_CONTINENTS keyword is set to 2.
; t3d: in, optional, type=boolean, default=0
; Set this graphics keyword if you wish to draw outlines use the T3D transformation matrix.
; This keyword is ignored if using FILENAME.
; thick: in, optional, type=integer, default=!P.Thick
; Set this keyword to the thickness of the lines that are drawn.
; usa: in, optional, type=boolean, default=0
; Set this keyword if you wish do draw United States state boundaries. This keyword is
; ignored if using FILENAME.
; zvalue: in, optional, type=float, default=0.0
; Set this keyword to the ZVALUE where the outlines should be drawn. Set to 0 by default.
; This keyword is ignored if using FILENAME.

; :History:
; Change History::
; Written by David W. Fanning, 7 November 2011.
; Added an ERASE=0 to the /NOGRAPHICS keyword on the Draw method call to cgMap. 27 Dec 2011. DWF
; Changed the default line thickness to !P.Thick to better support PostScript files. 28 Dec 2011. DWF.
; Modified slightly to allow a three-element byte array to be used as the COLOR. 18 April 2012. DWF.
; Added a BACKGROUND keyword. 31 Aug 2012. DWF.
; Implemented the OUTLINE keyword and make it default so outlines are drawn when, e.g., FILL_CONTINENTS=2. 23 Nov 2015. Joe Sapp.
