Specifying Pens
~~~~~~~~~~~~~~~
*pen*
The attributes of lines and symbol outlines as defined by *pen* is a
comma-delimited list of *width*, *color* and *style*, each of which
is optional. *width* can be indicated as a measure (in **p**\ oints
(this is the default), **c**\ entimeters, or **i**\ nches) or as
**faint**, **default**, **thin**\ [**ner**\ \|\ **nest**],
**thick**\ [**er**\ \|\ **est**], **fat**\ [**ter**\ \|\ **test**],
or **obese**. *color* specifies a gray shade or color (see
`Specifying Color`_ above). *style* is a combination of dashes '-' and
dots '.'. If any of the attributes is omitted their default or
previous setting will be retained. See GMT Cookbook & Technical
Reference Chapter 4 for more information.
