<H2>DESCRIPTION</H2><PRE>
<B>pstext</B> plots textstrings of variable size, font type, and
orientation. Various map projections are provided, with
the option to draw and annotate the map boundaries.
<I>PostScript</I> code is written to standard output. Greek char
acters, subscript, superscript, and small caps are sup
ported as follows: The sequence @~ toggles between the
selected font and Greek (Symbol). @%<I>no</I>% sets the font to
<I>no</I>; @%% resets the font to the starting font, @- toggles
subscripts on/off, @+ toggles superscript on/off, and @#
toggles small caps on/off. @@ prints the @ sign. @e, @o,
@a, @E, @O, @A give the accented Scandinavian characters.
Composite characters (overstrike) may be indicated with
the @!<char1><char2> sequence, which will print the two
characters on top of each other. To learn the octal codes
for symbols not available on the keyboard and some
accented European characters, see Section 4.16 and
Appendix F in the <B><A HREF="GMT.html">GMT</A></B> Technical Reference and Cookbook.
Note that WANT_EURO_FONT must be set to TRUE in your .gmt
defaults file in order to use the accented characters.
Using the <B>-W</B> option, a colored rectangle underlying the
text may be plotted (Does not work for strings with
sub/super scripts, symbols, or composite characters,
except in paragraph mode (<B>-M</B>)).
<I>textfile</I>
This file contains 1 or more records with (<I>x,</I> <I>y,</I>
<I>size,</I> <I>angle,</I> <I>fontno,</I> <I>justify,</I> <I>text</I>). If no file is
given, <B>pstext</B> will read standard input. <I>size</I> is
text size in points, <I>angle</I> is measured in degrees
counter-clockwise from horizontal, <I>fontno</I> sets the
font type, <I>justify</I> sets the alignment. If <I>fontno</I>
is not an integer, then it is taken to be a
textstring with the desired fontname. See the <B>gmt</B>
<B>defaults</B> man page for names and numbers of avaiable
fonts (or run <B>pstext</B> <B>-L</B>). The alignment refers to
the part of the textstring that will be mapped onto
the (<I>x,y</I>) point. Choose a 2 character combination
of L, C, R (for left, center, or right) and T, M, B
for top, middle, or bottom. e.g., BL for lower
left.
1:xxxxx, or width in UNIT (upper case modifier).
UNIT is cm, inch, or m, depending on the MEA
SURE_UNIT setting in .<A HREF="gmtdefaults.html">gmtdefaults</A>, but this can be
overridden on the command line by appending the c,
i, or m to the scale/width value.

nates are given instead of wesn.
</PRE>
<H2>OPTIONS</H2><PRE>
No space between the option flag and the associated argu
ments.
<B>-B</B> Sets map boundary tickmark intervals. See <B><A HREF="psbasemap.html">psbasemap</A></B>
for details.
<B>-C</B> Sets the clearance between the text and the sur
rounding box [0.15<B>c</B>/0.15<B>c</B> (or 0.05<B>i</B>/0.05<B>i</B>)]. Only
used if <B>-W</B> is specified.
<B>-D</B> Offsets the text from the projected (<I>x,y</I>) point by
<I>dx,dy</I> [0/0]. Use <B>-Dj</B> to offset the text away from
the point instead (i.e. the text's justification'
will determine the direction of the shift). In
paragraph mode (<B>-M</B>), one may append <B>v</B> which will
draw a line from the original point to the shifted
point. Optionally append a <I>pen</I> for this line.
<B>-E</B> Sets the viewpoint's azimuth and elevation (for
perspective view) [180/90].' (Not implemented for
paragraph mode).
<B>-G</B> Sets the gray-shade (0-255) or color (r/g/b, each
0-255) used for drawing the text. [Default is
black]
<B>-H</B> Input file(s) has Header record(s). Number of
header records can be changed by editing your .gmt
defaults file. If used, <B><A HREF="GMT.html">GMT</A></B> default is 1 header
record.
<B>-K</B> More <I>PostScript</I> code will be appended later
[Default terminates the plot system].
<B>-M</B> Paragraph mode. Files must be multiple segment
files. Segments are separated by a special record
whose first character must be <I>flag</I> [Default is
'>']. Starting in the 3rd column, we expect to
find information pertaining to the typesetting of a
text paragraph (the remaining lines until next seg
ment header). The information expected is (x y
size angle fontno justify linespace parwidth par
just), where <I>x</I> <I>y</I> <I>size</I> <I>angle</I> <I>fontno</I> <I>justify</I> are
defined above, while <I>linespace</I> and <I>parwidth</I> are the
linespacing and paragraph width, respectively. The
justification of the text paragraph is governed by
<I>parjust</I> which may be <B>l</B>(eft), <B>c</B>(enter), <B>r</B>(ight), or
<B>j</B>(ustified). The segment header is followed by one
or more lines with paragraph text. Text may contain
the escape sequences discussed above as well as
three more: @;<I>r/g/b</I>; changes the font color (@;;
resets it), @:<I>size</I>: changes the font size (@::
resets it), and @_ toggles underline on/off. Sepa
rate paragraphs with a blank line.
<B>-N</B> Do NOT clip text at map boundaries [Default will
clip].
<B>-O</B> Selects Overlay plot mode [Default initializes a
new plot system].
<B>-P</B> Selects Portrait plotting mode [<B><A HREF="GMT.html">GMT</A></B> Default is
Landscape, see gmtdefaults to change this].
<B>-S</B> Draw text outline. Append pen attributes. (Not
implemented for paragraph mode).
<B>-U</B> Draw Unix System time stamp on plot. User may spec
ify where the lower left corner of the stamp should
fall on the page relative to lower left corner of
plot. Optionally, append a label, or <B>c</B> (which will
plot the command string.). The GMT parameters
UNIX_TIME and UNIX_TIME_POS can affect the appear
ance; see the <B><A HREF="gmtdefaults.html">gmtdefaults</A></B> man page for details.
<B>-V</B> Selects verbose mode, which will send progress
reports to stderr [Default runs "silently"].
<B>-W</B> Paint a rectangle beneath the text string. Set
color [Default is no fill]. Append <B>o</B> to draw rect
angle outline, add a <I>pen</I> to specify pen attributes
[1/0/0/0]. Choose upper case <B>O</B> to get a rounded
rectangle (only in paragraph mode). Choose lower
case <B>c</B> to get a concave rectangle (only in para
graph mode). Choose upper case <B>C</B> to get a convex
<B>a</B> for absolute coordinates; the default (<B>r</B>) will
reset plot origin.
<B>-Z</B> For 3-D projections: Sets the z-level of the
basemap [0]. (Not implemented for paragraph mode).
<B>-:</B> Toggles between (longitude,latitude) and (lati
tude,longitude) input/output. [Default is (longi
tude,latitude)]. Applies to geographic coordinates
only.
<B>-c</B> Specifies the number of plot copies. [Default is 1]

<H2>EXAMPLES</H2><PRE>
To plot the outlines of the textstrings stored in the file
text.d on a Mercator plot with the given specifications,
try
pstext text.d <B>-R</B>-30/30/-10/20 <B>-Jm</B>0.1<B>i</B> <B>-P</B> <B>-B</B>5 <B>-S</B>0.5<B>p</B> >
plot.ps
To add a typeset figure caption for a 3-inch wide illus
tration, try
pstext <B>-R</B>0/3/0/5 <B>-JX</B>3<B>i</B> <B>-O</B> <B>-H</B> <B>-M</B> <B>-N</B> << EOF >> figure.ps
This is an optional header record
> 0 -0.5 12 0 4 LT 13p 3i j
@%5%Figure 1.@%% This illustration shows nothing useful,
but it still needs
a figure caption. Highlighted in @;255/0/0;red@;; you can
see the locations
of cities where it is @_impossible@_ to get any good Thai
food; these are to be avoided.

</PRE>
<H2>BUGS</H2><PRE>
Except for paragraph mode, the horizontal justification of
surrounding rectangles does not work when Greek symbols,
sub- and superscripts, and/or composite characters are
imbedded in the textstring. In paragraph mode, the pres
ence of composite characters and other escape sequences
may lead to unfortunate word splitting. Finally, the out
line option does not work with the escape sequences.
The <B>-N</B> option does not adjust the BoundingBox information
so you may have to post-process the PostScript outout with
epstool or ps2epsi to obtain a correct BoundingBox.
