|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".|
|Generate a character map for the lower half of each specified font. This is the default.|
|Generate a character map for the upper half of each specified font.|
|--octal||Number the characters in octal rather than in decimal (the default).|
|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.|
|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.|
|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".|
|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.|
|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".|
|Set the font used for the numbering of the characters in the character map(s) to be name, rather than the default.|
|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.|
|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.|
|Set the pen color to be name. An unrecognized name sets the pen color to the default, which is "black".|
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.
--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.
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 emulators 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.
