NAME

       plotfont - produce character maps of fonts supported by the plotting utilities

SYNOPSIS

       plotfont [ options ] fonts

DESCRIPTION

       plotfont  produces  a  character  map  for  any  font  that  is  supported by the plotting
       utilities, which include graph(1), plot(1), pic2plot(1), tek2plot(1), and the GNU  libplot
       2-D  graphics  export  library  (see  plot(3)).   Which fonts are supported depends on the
       output format, which is specified by the -T option.  A listing of the fonts  available  in
       any specified output format may be obtained with the --help-fonts option (see below).

       The  character  map,  or maps, will be written to standard output in the specified format.
       For example, the Times-Roman font is available  when  producing  Postscript  output.   The
       command  plotfont  -T ps Times-Roman > charmap.ps will yield a character map of the Times-
       Roman font, in a Postscript format that can be viewed or edited with the idraw(1)  drawing
       editor.   The  Times-Roman  font is also available when producing Fig output, which can be
       viewed or edited with the xfig(1) drawing editor.  The command plotfont -T fig Times-Roman
       >  charmap.fig  will  yield  the  same  character  map,  but  in Fig format rather than in
       Postscript format.

       As another example, the Univers font is  available  when  producing  PCL  5  output.   The
       command  plotfont -T pcl Univers > charmap.pcl will produce a character map of the Univers
       font, in PCL 5 format.

       When producing output for the X Window System, i.e., for a popped-up window, any  scalable
       X  Window  System  font  that  has  an  XLFD  (i.e.,  X  Logical Font Description) name is
       supported.  For example, the command plotfont -T X utopia-medium-r-normal will  pop  up  a
       window,  and draw a character map of the Utopia-Regular font.  "utopia-medium-r-normal" is
       a truncated version of the Utopia-Regular font's XLFD name.  The  Utopia-Regular  font  is
       available on most X Window System displays.

OPTIONS

   General Options
       -T type
       --output-format type
              Select type as the output format.  It may be "X", "png", "pnm", "gif", "svg", "ai",
              "ps", "cgm", "fig", "pcl", "hpgl", "regis", "tek", or "meta" (the default).   These
              refer  respectively to the X Window System, PNG (Portable Network Graphics) format,
              portable anymap format (PBM/PGM/PPM), a pseudo-GIF format that  does  not  use  LZW
              encoding,  the  new  XML-based  Scalable Vector Graphics format, the format used by
              Adobe Illustrator, Postscript or Encapsulated Postscript (EPS) that can  be  edited
              with  idraw(1),  CGM  format  (by  default,  confirming to the WebCGM profile), the
              format used by the xfig(1)  drawing  editor,  the  Hewlett-Packard  PCL  5  printer
              language,  the  Hewlett-Packard Graphics Language, ReGIS graphics format (which can
              be displayed by the dxterm(1) terminal emulator or by a VT330 or  VT340  terminal),
              Tektronix  format  (which  can be displayed by the xterm(1) terminal emulator), and
              device-independent GNU metafile format itself.  Unless type is "X", an output  file
              is produced and written to standard output.

              Files  in  PNG,  PNM,  pseudo-GIF,  AI, or Fig format contain only a single page of
              graphics.  So if the -T png option, the -T pnm option, the -T gif option, the -T ai
              option,  or the -T fig option is used, the output file will contain a character map
              for only the first-specified font.

              A listing of the fonts available in any specified output  format  may  be  obtained
              with  the  --help-fonts  option (see below).  If a requested font is unavailable, a
              default font will be substituted.  The default font is "Helvetica" for "X",  "svg",
              "ai",  "ps",  "cgm",  and "fig", "Univers" for "pcl", and "HersheySerif" for "png",
              "pnm", "gif", "hpgl", "regis", "tek", and "meta".

       -1
       --lower-half
              Generate a character map for the lower half of each specified font.   This  is  the
              default.

       -2
       --upper-half
              Generate a character map for the upper half of each specified font.

       -o
       --octal
              Number the characters in octal rather than in decimal (the default).

       -x
       --hexadecimal
              Number the characters in hexadecimal rather than in decimal (the default).

       --box  Surround  each  character  with  a  box, showing its extent to left and right.  The
              default is not to do this.

       -j row
       --jis-row row
              Generate a character map for row row of a Japanese font arranged according  to  JIS
              [Japanese  Industrial  Standard]  X0208.  The only such font currently available is
              the HersheyEUC [Extended Unix Code] font.  If used, this option  overrides  the  -1
              and  -2  options.   The  valid  rows  are 1...94.  In the JIS X0208 standard, Roman
              characters are located in row 3, and Japanese  syllabic  characters  (Hiragana  and
              Katakana)  are  located in rows 4 and 5.  Greek and Cyrillic characters are located
              in rows 6 and 7.  Japanese ideographic  characters  (Kanji)  are  located  in  rows
              16...84.

       --bg-color name
              Set  the  color  used  for  the  background  to  be name.  This is relevant only to
              plotfont -T X, plotfont -T png, plotfont -T pnm, plotfont -T gif, plotfont -T  svg,
              plotfont -T cgm, and plotfont -T regis.  An unrecognized name sets the color to the
              default, which is "white".  The environment variable BG_COLOR can equally  well  be
              used to specify the background color.

              If  the  -T  png  or -T gif option is used, a transparent PNG file or a transparent
              pseudo-GIF,  respectively,  may  be  produced  by  setting  the   TRANSPARENT_COLOR
              environment  variable to the name of the background color.  If the -T svg or -T cgm
              option is used, an output file without a background may be produced by setting  the
              background color to "none".

       --bitmap-size bitmap_size
              Set  the  size of the graphics display in which the character map(s) will be drawn,
              in terms of pixels, to be bitmap_size.  The default is "570x570".  This is relevant
              only  to  plotfont -T X, plotfont -T png, plotfont -T pnm, and plotfont -T gif, all
              of which produce bitmaps.  If you choose a rectangular  (non-square)  window  size,
              the  fonts  in  the  character  map(s)  will  be  scaled  anisotropically, i.e., by
              different factors in the horizontal and vertical directions.  For  plotfont  -T  X,
              this requires an X11R6 display.  Any font that cannot be scaled in this way will be
              replaced by a default scalable font, such as the vector font "HersheySerif".

              The environment variable BITMAPSIZE can equally well be used to specify the  window
              size.   For  backward  compatibility,  the  X  resource  Xplot.geometry may be used
              instead.

       --emulate-color option
              If option is yes, replace each color in the output by an appropriate shade of gray.
              This  is  seldom  useful, except when using plotfont -T pcl to prepare output for a
              PCL 5 device.  (Many monochrome PCL 5 devices, such as monochrome LaserJets,  do  a
              poor  job  of  emulating  color  on their own.)  You may equally well request color
              emulation by setting the environment variable EMULATE_COLOR to "yes".

       --numbering-font name
              Set the font used for the numbering of the characters in the character map(s) to be
              name, rather than the default.

       --page-size pagesize
              Set  the size of size of the page on which the character map(s) will be positioned.
              This is relevant only to plotfont -T svg, plotfont -T ai, plotfont -T ps,  plotfont
              -T  cgm,  plotfont  -T  fig, plotfont -T pcl, and plotfont -T hpgl.  The default is
              "letter", which means an 8.5 inch by 11 inch page.  Any ISO page size in the  range
              "a0"..."a4"  or ANSI page size in the range "a"..."e" may be specified ("letter" is
              an alias for "a" and "tabloid" is an alias for  "b").   "legal"  and  "ledger"  are
              recognized  page sizes also.  The environment variable PAGESIZE can equally well be
              used to specify the page size.

              The graphics display in which each character map is drawn will be a  square  region
              that would occupy nearly the full width of the specified page.  An alternative size
              for the graphics display can be specified.  For example, the  page  size  could  be
              specified  as  "letter,xsize=4in,ysize=6in",  or "a4,xsize=5.0cm,ysize=100mm".  For
              all of the above except plotfont -T hpgl, the graphics display will, by default, be
              centered  on the page.  For all of the above except plotfont -T svg and plotfont -T
              cgm, the graphics display may be repositioned manually, by specifying the  location
              of  its  lower  left  corner,  relative  to the lower left corner of the page.  For
              example, the page size could be specified as  "letter,xorigin=2in,yorigin=3in",  or
              "a4,xorigin=0.5cm,yorigin=0.5cm".  It is also possible to specify an offset vector.
              For  example,  the  page  size  could  be  specified  as  "letter,xoffset=1in",  or
              "letter,xoffset=1in,yoffset=1.2in", or "a4,yoffset=-1cm".  In SVG format and WebCGM
              format it is possible to specify the size of the  graphics  display,  but  not  its
              position.

       --rotation angle
              Rotate  the  graphics  display  by angle degrees.  Recognized values are "0", "90",
              "180", and "270".  "no" and "yes" are equivalent to  "0"  and  "90",  respectively.
              The environment variable ROTATION can also be used to specify a rotation angle.

       --pen-color name
              Set  the  pen  color  to  be  name.  An unrecognized name sets the pen color to the
              default, which is "black".

   Options for Metafile Output
       The following option is relevant only if the -T option is omitted or if -T meta  is  used.
       In  this  case  the output of plotfont will be in GNU graphics metafile format.  It may be
       translated to other formats by invoking plot(1).

       -O
       --portable-output
              Output the portable (human-readable) version of GNU metafile  format,  rather  than
              the  binary  version  (the  default).  The format of the binary version is machine-
              dependent.

   Informational Options
       --help Print a list of command-line options, and exit.

       --help-fonts
              Print a table of available fonts, and exit.  The table will depend on which  output
              format  is  specified with the -T option.  plotfont -T X, plotfont -T svg, plotfont
              -T ai, plotfont -T ps, plotfont -T cgm, and plotfont -T fig  each  support  the  35
              standard  Postscript fonts.  plotfont -T svg, plotfont -T pcl, and plotfont -T hpgl
              support the 45 standard PCL 5 fonts,  and  the  latter  two  support  a  number  of
              Hewlett-Packard  vector fonts.  All seven support a set of 22 Hershey vector fonts,
              as do plotfont -T png, plotfont -T pnm, plotfont -T gif,  plotfont  -T  regis,  and
              plotfont  -T  tek.  plotfont without a -T option in principle supports any of these
              fonts, since its output must be translated to other formats by invoking plot(1).

       --list-fonts
              Like --help-fonts, but lists the fonts in a single column to facilitate  piping  to
              other  programs.  If no output format is specified with the -T option, the full set
              of supported fonts is listed.

       --version
              Print the version number of plotfont and the plotting utilities package, and exit.

ENVIRONMENT

       The environment variables BITMAPSIZE,  PAGESIZE,  BG_COLOR,  EMULATE_COLOR,  and  ROTATION
       serve  as backups for the options --bitmap-size, --page-size, --bg-color, --emulate-color,
       and --rotation,  respectively.   The  remaining  environment  variables  are  specific  to
       individual output formats.

       plotfont  -T  X,  which  pops up a window on an X Window System display for each character
       map, checks the DISPLAY environment variable.  Its value determines the display that  will
       be used.

       plotfont  -T  png  and  plotfont -T gif, which produce output in PNG format and pseudo-GIF
       format respectively, are affected by the INTERLACE environment variable.  If its value  is
       "yes", the output will be interlaced.  Also, if the TRANSPARENT_COLOR environment variable
       is set to the name of a color, that color will be treated as transparent in the output.

       plotfont -T pnm, which  produces  output  in  portable  anymap  (PBM/PGM/PPM)  format,  is
       affected by the PNM_PORTABLE environment variable.  If its value is "yes", the output will
       be in a human-readable format rather than binary (the default).

       plotfont -T cgm, which produces output in CGM  (Computer  Graphics  Metafile)  format,  is
       affected  by  the  CGM_MAX_VERSION and CGM_ENCODING environment variables.  By default, it
       produces a binary-encoded version of CGM version 3 format.   For  backward  compatibility,
       the  version number may be reduced by setting CGM_MAX_VERSION to "2" or "1".  Irrespective
       of version, the output CGM file  will  use  the  human-readable  clear  text  encoding  if
       CGM_ENCODING  is  set  to "clear_text".  However, only binary-encoded CGM files conform to
       the WebCGM profile.

       plotfont -T pcl, which produces PCL 5 output for Hewlett-Packard printers and plotters, is
       affected  by  the  environment variable PCL_ASSIGN_COLORS.  It should be set to "yes" when
       producing PCL 5 output for a color printer  or  other  color  device.   This  will  ensure
       accurate  color  reproduction  by  giving  the output device complete freedom in assigning
       colors, internally, to its "logical pens".  If it is "no" then the device will use a fixed
       set  of  colored  pens,  and  will  emulate  other colors by shading.  The default is "no"
       because monochrome PCL 5 devices, which are much more common than colored ones,  must  use
       shading to emulate color.

       plotfont  -T hpgl, which produces Hewlett-Packard Graphics Language output, is affected by
       several environment variables.  The most important is HPGL_VERSION, which may  be  set  to
       "1",  "1.5",  or  "2"  (the  default).  "1" means that the output should be generic HP-GL,
       "1.5" means that the output should be suitable for the HP7550A graphics  plotter  and  the
       HP758x,  HP7595A  and  HP7596A drafting plotters (HP-GL with some HP-GL/2 extensions), and
       "2" means that the output should be modern HP-GL/2.  If the version is "1" or  "1.5"  then
       the  only available fonts will be vector fonts, and all lines will be drawn with a default
       width.  Additionally, if the version is "1" then the  filling  of  arbitrary  curves  with
       solid color will not be supported (circles and rectangles aligned with the coordinate axes
       may be filled, though).

       The position of the plotfont -T hpgl graphics display  on  the  page  can  be  rotated  90
       degrees  counterclockwise  by setting the HPGL_ROTATE environment variable to "yes".  This
       is not the same as the rotation obtained with the --rotation option, since it both rotates
       the  graphics  display  and repositions its lower left corner toward another corner of the
       page.  Besides "no" and "yes", recognized values for HPGL_ROTATE are "0", "90", "180", and
       "270".   "no" and "yes" are equivalent to "0" and "90", respectively.  "180" and "270" are
       supported only if HPGL_VERSION is "2" (the default).

       By default, plotfont -T hpgl will draw with a fixed set of pens.  Which pens  are  present
       may  be  specified by setting the HPGL_PENS environment variable.  If HPGL_VERSION is "1",
       the default value of HPGL_PENS is "1=black"; if HPGL_VERSION is "1.5" or "2", the  default
       value   of  HPGL_PENS  is  "1=black:2=red:3=green:4=yellow:5=blue:6=magenta:7=cyan".   The
       format should be self-explanatory.  By setting HPGL_PENS you may specify a color  for  any
       pen in the range #1...#31.  All color names recognized by the X Window System may be used.
       Pen #1 must always be present, though it need not be black.  Any other pen  in  the  range
       #1...#31 may be omitted.

       If  HPGL_VERSION  is  "2"  then  plotfont -T hpgl will also be affected by the environment
       variable HPGL_ASSIGN_COLORS.  If its value is "yes", then plotfont -T  hpgl  will  not  be
       restricted  to the palette specified in HPGL_PENS: it will assign colors to "logical pens"
       in the range #1...#31, as needed.  The default value is  "no"  because  other  than  color
       LaserJet printers and DesignJet plotters, not many HP-GL/2 devices allow the assignment of
       colors to logical pens.

       Opaque filling and the drawing of visible white lines are supported only  if  HPGL_VERSION
       is "2" and the environment variable HPGL_OPAQUE_MODE is "yes" (the default).  If its value
       is "no" then white lines (if any), which are normally drawn  with  pen  #0,  will  not  be
       drawn.   This  feature is to accommodate older HP-GL/2 devices.  HP-GL/2 pen plotters, for
       example, do not support opacity or the use of pen #0 to draw visible  white  lines.   Some
       older HP-GL/2 devices may, in fact, malfunction if asked to draw opaque objects.

       plotfont  -T  tek,  which produces output for a Tektronix terminal or emulator, checks the
       TERM environment variable.  If the value of TERM  is  a  string  beginning  with  "xterm",
       "nxterm", or "kterm", it is taken as a sign that plotfont is running in an X Window System
       VT100 terminal emulator: a copy of  xterm(1),  nxterm(1),  or  kterm(1).   Before  drawing
       graphics, plotfont -T tek will emit an escape sequence that causes the terminal emulator's
       auxiliary Tektronix window, which is normally hidden, to pop up.  After the  graphics  are
       drawn,  an  escape  sequence  that  returns  control  to the original VT100 window will be
       emitted.  The Tektronix window will remain on the screen.

       If the value of TERM is a string beginning with "kermit", "ansi.sys", or  "nansi.sys",  it
       is taken as a sign that plotfont is running in the VT100 terminal emulator provided by the
       MS-DOS version of kermit(1).  Before drawing graphics, plotfont -T tek will emit an escape
       sequence  that  switches  the  terminal  emulator  to  Tektronix  mode.  Also, some of the
       Tektronix control codes emitted by plotfont -T tek will be kermit-specific.  There will be
       a  limited  amount  of  color  support,  which is not normally the case (the 16 `ansi.sys'
       colors will be supported).  After drawing graphics, plotfont -T tek will  emit  an  escape
       sequence  that  returns  the  emulator to VT100 mode.  The key sequence `ALT minus' can be
       employed manually within kermit to switch between the two modes.
