<h2>DESCRIPTION</h2>
<p style="margin-left:11%; margin-top: 1em"><b>gmtdefaults</b>
lists the <b><A HREF="GMT.html">GMT</A></b> parameter defaults if the option
<b>−D</b> is used. There are three ways to change some
of the settings: (1) Use the command <b><A HREF="gmtset.html">gmtset</A></b>, (2) use
any texteditor to edit the file .gmtdefaults4 in your home,
~/.gmt or current directory (if you do not have this file,
run <b>gmtdefaults</b> -D > ~/.gmtdefaults4 to get one
with the system default settings), or (3) override any
parameter by specifying one or more
<b>−−PARAMETER</b>=<i>value</i> statements on
the commandline of any <b><A HREF="GMT.html">GMT</A></b> command (<b>PARAMETER</b>
and <b>VALUE</b> are any combination listed below). The
first two options are permanent changes until explicitly
changed back, while the last option is ephemeral and only
applies to the single <b><A HREF="GMT.html">GMT</A></b> command that received the
override. <b><A HREF="GMT.html">GMT</A></b> can provide default values in US or SI
units. This choice is determined by the contents of the
gmt.conf file in <b><A HREF="GMT.html">GMT</A></b>’s share directory.</p>

<a name="GMT PARAMETERS"></a>
<h2>GMT PARAMETERS</h2>
<p style="margin-left:11%; margin-top: 1em">The following
is a list of the parameters that are user-definable in
<b><A HREF="GMT.html">GMT</A></b>. The parameter names are always given in UPPER
CASE. The parameter values are case-insensitive unless
otherwise noted. The system defaults are given in brackets [
for SI (and US) ]. Those marked <b>*</b> can be set on the
command line as well (the corresponding option is given in
parentheses). Note that default distances and lengths below
are given in both cm or inch; the chosen default depends on
your choice of default unit (see <b><A HREF="gmtdefaults.html#MEASURE_UNIT">MEASURE_UNIT</A></b>). You
can explicitly specify the unit used for distances and
lengths by appending <b>c</b> (cm), <b>i</b> (inch),
<b>m</b> (meter), or <b>p</b> (points). When no unit is
indicated the value will be assumed to be in the unit set by
<b><A HREF="gmtdefaults.html#MEASURE_UNIT">MEASURE_UNIT</A></b>. Note that the printer resolution
<b><A HREF="gmtdefaults.html#DOTS_PR_INCH">DOTS_PR_INCH</A></b> is always the number of dots or pixels
per inch. Several parameters take only TRUE or FALSE.

rectangular projections, polar projections). For situations
where all boundary ticks and annotations must be inside the

range). A <b><A HREF="gmtdefaults.html#COLOR_MODEL">COLOR_MODEL</A></b> setting in the color palette

interpolation takes place directly on the RGB values which
can give unexpected hues, whereas interpolation directly on

point is indicated then the smallest specified unit will be
rounded off to nearest integer. For 12-hour clocks, append
am, AM, a.m., or A.M. (<b><A HREF="GMT.html">GMT</A></b> will replace a|A with p|P
for pm). If your template starts with a leading hyphen (-)

plotted as this depends on the annotation interval.</p>
<p style="margin-left:11%;"><b><A NAME="POLAR_CAP">POLAR_CAP</A></b></p>

gridlines near the poles for all azimuthal projections and a
few others in which the geographic poles are plotted as
points (Lambert Conic, Hammer, Mollweide, Sinusoidal, and
van der Grinten). Specify either none (in which case there
is no special handling) or <i>pc_lat</i>/<i>pc_dlon</i>. In
that case, normal gridlines are only drawn between the
latitudes -<i>pc_lat</i>/+<i>pc_lat</i>, and above those
latitudes the gridlines are spaced at the (presumably
coarser) <i>pc_dlon</i> interval; the two domains are
separated by a small circle drawn at the <i>pc_lat</i>
latitude [85/90]. Note for r-theta (polar) projection where
r = 0 is at the center of the plot the meaning of the cap is
reversed, i.e., the default 85/90 will draw a r = 5 radius
circle at the center of the map with less frequent radial
lines there.</p>
<p style="margin-left:11%;"><b><A NAME="PS_COLOR">PS_COLOR</A></b></p>
<p style="margin-left:22%;">Determines whether
<i>PostScript</i> output should use RGB, HSV, CMYK, or GRAY
when specifying color [rgb]. Note if HSV is selected it does
not apply to images which in that case uses RGB. When
selecting GRAY, all colors will be converted to gray scale
using YIQ (television) conversion.</p>
<p style="margin-left:11%;"><b><A NAME="PS_IMAGE_COMPRESS">PS_IMAGE_COMPRESS</A></b></p>
<p style="margin-left:22%;">Determines if <i>PostScript</i>

(none) [lzw].</p>
<p style="margin-left:11%;"><b><A NAME="PS_IMAGE_FORMAT">PS_IMAGE_FORMAT</A></b></p>
<p style="margin-left:22%;">Determines whether images
created in <i>PostScript</i> should use ASCII or binary
format. The latter takes up less space and executes faster
but may choke some printers, especially those off serial
ports. Select ascii or bin [ascii].</p>
<p style="margin-left:11%;"><b><A NAME="PS_LINE_CAP">PS_LINE_CAP</A></b></p>
<p style="margin-left:22%;">Determines how the ends of a
line segment will be drawn. Choose among a <i>butt</i> cap
(default) where there is no projection beyond the end of the
path, a <i>round</i> cap where a semicircular arc with
diameter equal to the linewidth is drawn around the end
points, and <i>square</i> cap where a half square of size
equal to the linewidth extends beyond the end of the path
[butt].</p>
<p style="margin-left:11%;"><b><A NAME="PS_LINE_JOIN">PS_LINE_JOIN</A></b></p>
<p style="margin-left:22%;">Determines what happens at
kinks in line segments. Choose among a <i>miter</i> join
where the outer edges of the strokes for the two segments
are extended until they meet at an angle (as in a picture
frame; if the angle is too acute, a bevel join is used
instead, with threshold set by <b><A HREF="gmtdefaults.html#PS_MITER_LIMIT">PS_MITER_LIMIT</A></b>),
<i>round</i> join where a circular arc is used to fill in
the cracks at the kinks, and <i>bevel</i> join which is a
miter join that is cut off so kinks are triangular in shape
[miter].</p>
<p style="margin-left:11%;"><b><A NAME="PS_MITER_LIMIT">PS_MITER_LIMIT</A></b></p>
<p style="margin-left:22%;">Sets the threshold angle in
degrees (integer in 0-180 range) used for mitered joins
only. When the angle between joining line segments is
smaller than the threshold the corner will be bevelled
instead of mitered. The default threshold is 35 degrees.
Setting the threshold angle to 0 implies the
<i>PostScript</i> default of about 11 degrees. Setting the
threshold angle to 180 causes all joins to be beveled.</p>
<p style="margin-left:11%;"><b><A NAME="PS_VERBOSE">PS_VERBOSE</A></b></p>
<p style="margin-left:22%;">If TRUE we will issue comments
in the <i>PostScript</i> file that explain the logic of
operations. These are useful if you need to edit the file
and make changes; otherwise you can set it to FALSE which
yields a somewhat slimmer <i>PostScript</i> file
[FALSE].</p>
<p style="margin-left:11%;"><b><A NAME="TICK_LENGTH">TICK_LENGTH</A></b></p>
<p style="margin-left:22%;">The length of a tickmark.
Normally, tickmarks are drawn on the outside of the map
boundaries. To select interior tickmarks, use a negative
tick_length [0.2<b>c</b> (or 0.075<b>i</b>)].</p>
<p style="margin-left:11%;"><b><A NAME="TICK_PEN">TICK_PEN</A></b></p>
<p style="margin-left:22%;">Pen attributes to be used for
tickmarks in dpi units or points (append p) [0.5p].</p>
<p style="margin-left:11%;"><b><A NAME="TIME_EPOCH">TIME_EPOCH</A></b></p>
<p style="margin-left:22%;">Specifies the value of the
calendar and clock at the origin (zero point) of relative
time units (see <b><A HREF="gmtdefaults.html#TIME_UNIT">TIME_UNIT</A></b>). It is a string of the
form yyyy-mm-ddT[hh:mm:ss] (Gregorian) or
yyyy-Www-ddT[hh:mm:ss] (ISO) Default is 2000-01-01T12:00:00,
the epoch of the J2000 system.</p>
<p style="margin-left:11%;"><b><A NAME="TIME_FORMAT_PRIMARY">TIME_FORMAT_PRIMARY</A></b></p>
<p style="margin-left:22%;">Controls how primary month-,
week-, and weekday-names are formatted. Choose among full,
abbreviated, and character. If the leading f, a, or c are
replaced with F, A, and C the entire annotation will be in
upper case.</p>
<p style="margin-left:11%;"><b><A NAME="TIME_FORMAT_SECONDARY">TIME_FORMAT_SECONDARY</A></b></p>
<p style="margin-left:22%;">Controls how secondary month-,
week-, and weekday-names are formatted. Choose among full,
abbreviated, and character. If the leading f, a, or c are
replaced with F, A, and C the entire annotation will be in
upper case.</p>
<p style="margin-left:11%;"><b><A NAME="TIME_INTERVAL_FRACTION">TIME_INTERVAL_FRACTION</A></b></p>
<p style="margin-left:22%;">Determines if partial intervals
at the start and end of an axis should be annotated. If the
range of the partial interval exceeds the specified fraction
of the normal interval stride we will place the annotation
centered on the partial interval [0.5].</p>
<p style="margin-left:11%;"><b><A NAME="TIME_IS_INTERVAL">TIME_IS_INTERVAL</A></b></p>
<p style="margin-left:22%;">Used when input calendar data
should be truncated and adjusted to the middle of the
relevant interval. In the following discussion, the unit
<b>u</b> can be one of these time units: (<b>y</b> year,
<b>o</b> month, <b>u</b> ISO week, <b>d</b> day, <b>h</b>
hour, <b>m</b> minute, and <b>c</b> second).
<b><A HREF="gmtdefaults.html#TIME_IS_INTERVAL">TIME_IS_INTERVAL</A></b> can have any of the following three
values: (1) OFF [Default]. No adjustment, time is decoded as
given. (2) +<i>n</i><b>u</b>. Activate interval adjustment
for input by truncate to previous whole number of <i>n</i>
units and then center time on the following interval. (3)
-<i>n</i><b>u</b>. Same, but center time on the previous
interval. For example, with <b><A HREF="gmtdefaults.html#TIME_IS_INTERVAL">TIME_IS_INTERVAL</A></b> = +1o,
an input data string like 1999-12 will be interpreted to
mean 1999-12-15T12:00:00.0 (exactly middle of December),
while if <b><A HREF="gmtdefaults.html#TIME_IS_INTERVAL">TIME_IS_INTERVAL</A></b> = OFF then that date is

<p style="margin-left:11%;"><b><A NAME="TRANSPARENCY">TRANSPARENCY</A></b></p>
<p style="margin-left:22%;">Makes printed material
transparent. Specify transparency in percent: 0 is opaque
(normal overlay plotting), 100 is fully transparent (i.e.,
nothing will show). Use either as a pair
(<i>stroke</i>/<i>fill</i>) to set the transparency of
stroked material (lines) or filled material (polygons)
separately, or use a single number to set both to the same
value [0]. <b><br>
Warning:</b> Most printers and <i>PostScript</i> viewers can
not print or will not show transparency. They will simply
ignore your attempt to create transparency and will plot any
material as opaque. <i>Ghostscript</i> and all its
derivatives like <b><A HREF="ps2raster.html">ps2raster</A></b>, Apple’s
<i>Preview</i> and the <i>CUPS</i> printing system are among
those programs incapable of dealing with transparency. If
you want to view transparent material you need to use
<i>Acrobat Distiller</i> to create a PDF file. Note that the
settings of <i>Acrobat Distiller</i> need to be changed to
make transparency effective: change /AllowTransparency to
true in the .joboptions file.</p>

%b %d %H:%M:%S].</p>
<p style="margin-left:11%;"><b><A NAME="VECTOR_SHAPE">VECTOR_SHAPE</A></b></p>
<p style="margin-left:22%;">Determines the shape of the
head of a vector. Normally (i.e., for vector_shape = 0), the
head will be triangular, but can be changed to an arrow (1)
or an open V (2). Intermediate settings give something in
between. Negative values (up to -2) are allowed as well
[0].</p>
