NAME

       tek2plot - translate Tektronix files to other graphics formats

SYNOPSIS

       tek2plot [ options ] [ files ]

DESCRIPTION

       tek2plot  translates  Tektronix  graphics files to other formats, or displays them on an X
       Window System display.  The output format is specified with the -T option.   The  possible
       output  formats  are  the  same  as those supported by graph(1), plot(1), pic2plot(1), and
       plotfont(1).  If an output file is produced, it is written to standard output.

       Options and file names may be interspersed on  the  command  line,  but  the  options  are
       processed  before the file names are read.  If -- is seen, it is interpreted as the end of
       the options.  If no file names are specified, or the  file  name  -  is  encountered,  the
       standard input is read.

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  itself, and device-independent GNU metafile format.  Unless type
              is "X", an output file is produced and written to standard output.

              Omitting the -T option is equivalent to specifying -T meta.   GNU  metafile  format
              may be translated to other formats with plot(1).

       -p n
       --page-number n
              Output only page number n, within the Tektronix file or sequence of Tektronix files
              that is being translated.  n must be a non-negative integer, since a Tektronix file
              may consist of one or more pages, numbered beginning with zero.

              The  default  behavior if the -p option is not used is to output all nonempty pages
              in succession.  For example, tek2plot -T X displays each Tektronix page in its  own
              X  window.   If  the  -T  png, -T pnm, -T gif, -T ai, or -T fig option is used, the
              default behavior is to output only the first nonempty Tektronix page,  since  files
              in those output formats contain only a single page of graphics.

              Most  Tektronix  files  consist of either one page (page #0) or two pages (an empty
              page #0, and page #1).  Tektronix files produced  by  the  GNU  plotting  utilities
              (e.g., by graph -T tek) are normally of the latter sort.

       -F name
       --font-name name
              Use  the  font  name  for rendering the native Textronix fonts, if it is available.
              The default font is "Courier" except for tek2plot -T png, tek2plot -T pnm, tek2plot
              -T  gif,  tek2plot -T hpgl, tek2plot -T regis, and tek2plot -T tek, for which it is
              "HersheySerif".  A list of available fonts can be obtained  with  the  --help-fonts
              option   (see  below).   If  a  font  outside  the  Courier  family  is  used,  the
              --position-chars option (see below) should probably be specified.

              The -F option is useful only if you have a Tektronix file  that  draws  text  using
              native  Tektronix  fonts.   Tektronix  files produced by the GNU plotting utilities
              (e.g., by graph -T tek) do not use native Tektronix fonts: they use Hershey  vector
              fonts instead.

       -W line_width
       --line-width line_width
              Set  the  width  of  lines,  as  a  fraction  of  the  width  of the display, to be
              line_width.  A negative value means that a default  value  should  be  used.   This
              value  is  format-dependent.  The interpretation of zero line width is also format-
              dependent (in some output formats, a zero-width line is the thinnest line that  can
              be drawn; in others, a zero-width line is invisible).

       --bg-color name
              Set  the  color  used  for  the  background  to  be name.  This is relevant only to
              tek2plot -T X, tek2plot -T png, tek2plot -T pnm, tek2plot -T gif, tek2plot -T  svg,
              tek2plot -T cgm, and tek2plot -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 svg or -T cgm option is used, an
              output file without a background may be produced by setting the background color to
              "none".

              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.

       --bitmap-size bitmap_size
              Set  the  size of the graphics display in which the plot will be drawn, in terms of
              pixels, to be bitmap_size.  The default is "570x570".  This  is  relevant  only  to
              plot  -T X, plot -T png, plot -T pnm, and plot -T gif.  If you choose a rectangular
              (non-square) window size, the fonts in the plot  will  be  scaled  anisotropically,
              i.e.,  by different factors in the horizontal and vertical directions.  For plot -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 ` tek2plot -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".

       --max-line-length max_line_length
              Set  the  maximum  number of points that a polygonal line may contain, before it is
              flushed out, to be max_line_length.  If this flushing occurs,  the  polygonal  line
              will  be  split  into  two  or  more  sub-lines, though the splitting should not be
              noticeable.  The default value of max_line_length is 500.

              The reason for splitting long polygonal lines is that some display  devices  (e.g.,
              old  Postscript  printers  and  HP-GL pen plotters) have limited buffer sizes.  The
              environment variable MAX_LINE_LENGTH can also be used to specify the  maximum  line
              length.

       --page-size pagesize
              Set  the  size  of the page on which the plot will be positioned.  This is relevant
              only to tek2plot -T svg, tek2plot -T ai, tek2plot -T ps, tek2plot -T cgm,  tek2plot
              -T  fig,  tek2plot  -T  pcl,  and tek2plot -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 the plot 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 tek2plot -T hpgl, the graphics display will, by default,  be  centered
              on  the page.  For all of the above except tek2plot -T svg and tek2plot -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.

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

       --position-chars
              Position the characters in each text string individually.  If the text font is  not
              a  member  of  the  Courier family, and especially if it is not a fixed-width font,
              this option is recommended.  It will improve the appearance of text strings, at the
              price  of  making  it  difficult to edit the output file with xfig(1), idraw(1), or
              Illustrator.

       --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.

       --use-tek-fonts
              Use the bitmap fonts that were used on the original Tektronix  4010/4014  terminal.
              This  option is relevant only to tek2plot -T X.  The four relevant bitmap fonts are
              distributed with most versions of the  GNU  plotting  utilities,  under  the  names
              "tekfont0"..."tekfont3".   They  can  easily  be  installed  on any modern X Window
              System display.  For this option to work properly, you must also  select  a  window
              size  of 1024x1024 pixels, either by using the --bitmap-size 1024x1024 option or by
              setting the value of the Xplot.geometry resource.  This is  because  bitmap  fonts,
              unlike the scalable fonts that tek2plot normally uses, cannot be rescaled.

              This  option  is useful only if you have a file in Tektronix format that draws text
              using native Tektronix  fonts.   Tektronix  files  produced  by  the  GNU  plotting
              utilities  (e.g.,  by  graph  -T  tek)  do not use native Tektronix fonts: they use
              Hershey vector fonts instead.

   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 tek2plot outputs a GNU graphics metafile, which must be translated to other
       formats with plot(1).

       -O
       --portable-output
              Output the portable (human-readable) version of GNU metafile format, rather than  a
              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.  tek2plot -T X, tek2plot -T svg, tek2plot
              -T ai, tek2plot -T ps, tek2plot -T cgm, and tek2plot -T fig  each  support  the  35
              standard  Postscript fonts.  tek2plot -T svg, tek2plot -T pcl, and tek2plot -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 tek2plot -T png, tek2plot -T pnm, tek2plot -T gif,  tek2plot  -T  regis,  and
              tek2plot  -T  tek.  tek2plot without a -T option in principle supports any of these
              fonts, since its output must be translated to other formats with plot(1).

              The plotfont(1) utility may be used to obtain a  character  map  of  any  supported
              font.

       --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 tek2plot and the plotting utilities package, and exit.

ENVIRONMENT

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

       tek2plot -T X, which pops up a window on an X Window System display and draws graphics  in
       it,  checks  the DISPLAY environment variable.  Its value determines the display that will
       be used.

       tek2plot -T png and tek2plot -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.

       tek2plot  -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).

       tek2plot  -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.

       tek2plot -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.

       tek2plot -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 (the -W option will not work).

       The  position  of  the  tek2plot  -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,  tek2plot -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 tek2plot -T hpgl will also  be  affected  by  the  environment
       variable  HPGL_ASSIGN_COLORS.   If  its  value is "yes", then tek2plot -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.

       The  drawing  of  visible  white  lines  is  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  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.
