DESCRIPTION

      pstext 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
      4.15 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).

      textfile
           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 lower
           left.

      -J   Selects the map projection. Scale is inch/degree, 1:xxxxx, or
           width in inch (upper case modifier).

      -Jz  Sets the vertical scaling (for 3-D maps).  Same syntax as -Jx.

      -R   west, east, south, and north specify the Region of interest.  To
           specify boundaries in degrees and minutes [and seconds], use the
           dd:mm[:ss] format.  Append r if lower left and upper right map
           coordinates are given instead of wesn.

OPTIONS

      No space between the option flag and the associated arguments.

      -B   Sets map boundary tickmark intervals. See psbasemap for details.

      -C   Sets the clearance (in inch) between the text and the surrounding
           box [0.05i/0.05i].  Only used if -W is specified.

      -D   Shifts the projected (x,y) point by dx,dy (in inch) [0/0].

      -E   Sets the viewpoint's azimuth and elevation (for perspective view)
           [180/90]

      -G   Sets the gray-shade (0-255) or color (r/g/b, each 0-255) used for
           drawing the text.  [Default is black]

      -H   Input 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.

      -K   More PostScript code will be appended later [Default terminates
           the plot system].

      -L   Lists the font-numbers and font-names available, then exits.

      -N   Do NOT clip text at map boundaries [Default will clip].

      -O   Selects Overlay plot mode [Default initializes a new plot
           system].

      -P   Selects Portrait plotting mode [GMT Default is Landscape, see
           gmtdefaults to change this].

      -S   Draw text outline. Append pen attributes.

      -U   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 in inch [Default is (-0.75i/-
           0.75i)].  Optionally, append a label, or c (which will plot the
           command string.)

      -V   Selects verbose mode, which will send progress reports to stderr
           [Default runs "silently"].

      -W   Paint a rectangle beneath the text string.  Set color [Default is
           255/255/255 (white)].  Append o to draw rectangle outline, add a
           pen to specify pen attributes [1/0/0/0]

      -X -Y
           Shift origin of plot by (x-shift,y-shift) inch  [Default is
           (a1i,a1i) for new plots, (0,0) for overlays].  Prepend a for
           absolute coordinates; the default (r) will reset plot origin.


      -Z   For 3-D projections:  Sets the z-level of the basemap [0].

      -:   Toggles between (longitude,latitude) and (latitude,longitude)
           input/output.  [Default is (longitude,latitude)].

      -c   Specifies the number of plot copies. [Default is 1]

EXAMPLES

      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 -R-30/30/-10/20 -Jm0.1i -P -B5 -S0.5p > plot.ps

BUGS

      The horizontal justification of surrounding rectangles does not work
      when Greek symbols, sub- and superscripts, and/or composite characters
      are imbedded in the textstring.
