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 4.16 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  rec-
       tangle  underlying  the	text may be plotted (Does not work for strings with sub/super scripts, symbols, or composite characters, except in
       paragraph mode (-M)).

       textfile
	      This file contains 1 or more records with (x, y, size, angle, fontno, justify, text).  If no file is given, pstext will  read  stan-
	      dard 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 UNIT/degree, 1:xxxxx, or width in UNIT (upper case modifier).  UNIT is cm, inch, or m, depend-
	      ing 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.

	      NON-GEOGRAPHICAL PROJECTIONS:

	      -Jxx-scale[l|ppow][/y-scale[l|ppow]] (Linear, log, and power scaling)
	      More details can be found in the psbasemap manpages.

       -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 between the text and the surrounding box [0.15c/0.15c (or 0.05i/0.05i)].  Only used if -W is specified.

       -D     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.

       -E     Sets the viewpoint's azimuth and elevation (for perspective view) [180/90].'  (Not implemented for paragraph mode).

       -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.

       -M     Paragraph  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, respec-
	      tively.  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 under-
	      line on/off. Separate paragraphs with a blank line.

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

       -bo    Selects binary output. Append s for single precision [Default is double].

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

       -S     Draw text outline. Append pen attributes.  (Not implemented for paragraph mode).

       -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. Optionally, append a label, or c (which will plot the command string.). The GMT parameters UNIX_TIME and
	      UNIX_TIME_POS can affect the appearance; see the gmtdefaults man page for details.

       -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 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.

       -Z     For 3-D projections: Sets the z-level of the basemap [0].  (Not implemented for paragraph mode).

       -:     Toggles between (longitude,latitude) and (latitude,longitude) input/output. [Default  is	(longitude,latitude)].	 Applies  to  geo-
	      graphic coordinates only.

       -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

       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
       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.
       EOF

BUGS

       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.  Finally, the outline option does not work with the escape sequences.
       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.
