plots textstrings of variable size, font type, and orientation. Various
map projections are provided, with the option to draw and annotate the
map boundaries. PostScript code is written to standard output. Greek characters,
subscript, superscript, and small caps are supported as follows: The sequence
@~ toggles between the selected font and Greek (Symbol). @%no% sets the
font to no; @%% 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 GMT Technical Reference and Cookbook. Note that WANT_EURO_FONT must
be set to TRUE in your .gmtdefaults file in order to use the accented characters.
Using the -W 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 (-M)).
No space between the option flag and the associated arguments.
- This file contains 1
or more records with (x, y, size, angle, fontno, justify, text). If no file
is given, pstext will read standard input. size is text size in points,
angle is measured in degrees counter-clockwise from horizontal, fontno
sets the font type, justify sets the alignment. If fontno is not an integer,
then it is taken to be a textstring with the desired fontname. See the
gmtdefaults man page for names and numbers of avaiable fonts (or run pstext
-L). The alignment refers to the part of the textstring that will be mapped
onto the (x,y) 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
- Selects the map projection. Scale is UNIT/degree, 1:xxxxx,
or width in UNIT (upper case modifier). UNIT is cm, inch, or m, depending
on the MEASURE_UNIT setting in .gmtdefaults, but this can be overridden
on the command line by appending the c, i, or m to the scale/width value.

south, and north specify the Region of interest. To specify boundaries
in degrees and minutes [and seconds], use the dd:mm[:ss] format. Append

- Sets map boundary tickmark intervals. See psbasemap for details.
- Sets the
clearance between the text and the surrounding box [0.15c/0.15c (or 0.05i/0.05i)].
Only used if -W is specified.
- Offsets the text from the projected (x,y)
point by dx,dy [0/0]. Use -Dj 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 (-M), one may append v which will draw a line from the
original point to the shifted point. Optionally append a pen for this line.
- Sets the viewpoint’s azimuth and elevation (for perspective view) [180/90].
(Not implemented for paragraph mode).
- Sets the gray-shade (0-255) or color
(r/g/b, each 0-255) used for drawing the text. [Default is black]
file(s) has Header record(s). Number of header records can be changed by
editing your .gmtdefaults file. If used, GMT default is 1 header record.

mode. Files must be multiple segment files. Segments are separated by a
special record whose first character must be flag [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 segment header). The
information expected is (x y size angle fontno justify linespace parwidth
parjust), where x y size angle fontno justify are defined above, while
linespace and parwidth are the linespacing and paragraph width, respectively.
The justification of the text paragraph is governed by parjust which may
be l(eft), c(enter), r(ight), or j(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: @;r/g/b; changes the font color
(@;; resets it), @:size: changes the font size (@:: resets it), and @_
toggles underline on/off. Separate paragraphs with a blank line.

clip text at map boundaries [Default will clip].
- Selects Overlay plot
mode [Default initializes a new plot system].
- Selects Portrait plotting
mode [GMT Default is Landscape, see gmtdefaults to change this].
text outline. Append pen attributes. (Not implemented for paragraph mode).
- Draw Unix System time stamp on plot. User may specify 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 c (which will plot the command
- Selects verbose mode, which will send progress reports to stderr
[Default runs "silently"].
- Paint a rectangle beneath the text string.
Set color [Default is no fill]. Append o to draw rectangle outline, add
a pen to specify pen attributes [1/0/0/0]. Choose upper case O to get a
rounded rectangle (only in paragraph mode). Choose lower case c to get a
concave rectangle (only in paragraph mode). Choose upper case C to get a
convex rectangle (only in paragraph mode).
- -X -Y
- Shift origin of plot by (x-shift,y-shift).
Prepend a for absolute coordinates; the default (r) will reset plot origin.
- For 3-D projections: Sets the z-level of the basemap . (Not implemented
for paragraph mode).
- Toggles between (longitude,latitude) and (latitude,longitude)
input/output. [Default is (longitude,latitude)]. Applies to geographic coordinates
- Specifies the number of plot copies. [Default is 1]

To add a typeset figure caption for a 3-inch wide illustration, try
pstext -R0/3/0/5 -JX3i -O -H -M -N << EOF >> figure.ps
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 presence of composite characters and other escape sequences may lead
to unfortunate word splitting.

The -N 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.
