ccolor: in, optional, type=string, default='Charcoal'
The name of a color the map continents should be displayed with. The default
is "charcoal". Color names are those supported by cgColor.
continents: in, optional, type=boolean, default=0
If a cgMap object is made successfully, then setting this keyword
will add a cgMapContinents object to the cgMap object.
gcolor: in, optional, type=string, default='Gray'
The name of a color the map grid should be displayed with. The default
is "gray". Color names are those supported by cgColor.
grid: in, optional, type=boolean, default=0
If a cgMap object is made successfully, then setting this keyword
will add a cgMapGrid object to the cgMap object.
mcolor: in, optional, type=string, default='Black'
The name of a color the map should be displayed in. (Normally the map
border and map title are displayed in this color.)
onimage: in, optional, type=boolean, default=0
Set this keword if the map object is to get its position from the last
cgImage command issued.
silent: in, optional, type=boolean, default=0
IDL cannot map every GeoTiff image to a supported map projection or datum.
Normally, if the GeoTIFF image is unsupported, an error message is issued.
Setting this keyword will suppress such error messages. If you do this, you
MUST check the SUCCESS keyword to see if the program ran successfully. (Of
course, it is a good idea to check it in any case!)
success: out, optional, type=boolean, default=0
An output variable that will contain a 1 if the map coordinate object was
created successfully. Or to a 0 if it was not created successfully.
title: in, optional, type=string, default=""
The title of the map projection.
use_latlon: in, optional, type=boolean, default=0
If this keyword is set, the boundary ranges will be forced to be determined
from the latitude and longitude arrays in the file.
xrange: out, optional, type=double
The discovered X projected meter range of the map projection.
yrange: out, optional, type=double
The discovered Y projected meter range of the map projection.
