NAME
xfig - Facility for Interactive Generation of figures under X11
Version 3.2.7b
SYNOPSIS
xfig [options] [file]
DESCRIPTION
Xfig is a menu-driven tool that allows the user to draw and manipulate objects
interactively under the X Window System. It runs under X version 11 release 4 or higher
and requires a two- or three-button mouse. file specifies the name of a file to be
edited. The objects in the file will be read at the start of xfig.
The bulk of the documentation for xfig is in an HTML-based reference guide. See the Help
menu in xfig or point your browser at /usr/share/doc/xfig/html/index.html. There are both
English and Japanese versions.
When using a two-button mouse use the <Meta> key and the right button at the same time to
effect the action of the middle button.
Xfig is available from https://sourceforge.net/projects/mcj/.
The Fig2dev package is used when printing or exporting the output from xfig. The fig2dev
program is automatically called by xfig as a back-end processor to produce various types
of output:
LaTeX, Metafont, PDF, PostScript or Encapsulated PostScript, CGM and EMF (mostyl used
under Windows), tk (tcl/tk tool command language/tool kit package), SVG, GIF, JPEG, PCX,
PNG, PPM, TIFF, XBM, XPM, Gerber, AutoCAD Slide, IBM-GL (HP/GL), Pic and PiCTeX. For use
with TeX/LaTeX: box, epic, eepic, eepicemu, pict2e, pstricks, tikz.
See man fig2dev for all options.
The Fig2dev package is available from https://sourceforge.net/projects/mcj/.
OPTIONS
-help
Print all command-line options for xfig and quit.
-a[llownegcoords]
Allow panning into the negative region of the canvas. This is the default
-au[torefresh] Make xfig look at the timestamp on the .fig file and automatically load it
and display it every time it changes.
-bal[loon_delay] msec
Cause popup information balloons to be delayed by msec milliseconds. The default
is 500 milliseconds.
-bol[d] font
Cause the font used for displaying the file name and confirmation messages to be
font (default = 8x13bold).
-butt[on] font
Cause the font used for most buttons to be font (default = 6x13).
-but_[per_row] number
Specify the number of buttons wide the mode panel should be. This is useful in
conjunction with the -pheight parameter to reduce the canvas height for small
screens.
-cbg color
Use color as the background color for the canvas. If you want to set the
background of everything in xfig (e.g. menus, etc.) use the general -bg option.
-center
Set the print option to print the figure centered on the page. This is the
default.
-centim[ers]
Make centimeters the unit of choice. See also -metric.
-cfg color
Use color as the default color for objects. If you want to set the foreground of
everything in xfig (e.g. menus, etc.) use the general -fg option.
-correct_font_size
Normally, fig2dev uses 1/80 inch for font size increments (for historical reasons),
instead of the more proper ``points'' (1/72 inch) that xfig uses. This option
makes xfig call fig2dev with the -F option to make it use points (1/72 inch).
-deb[ug]
Turn on debugging mode. Prints various debugging messages like font names etc.
-dep[th]
Choose depth of visual desired. Your server must support the desired visual and
depth chosen. Use xdpyinfo to see what visuals and depths are supported. See also
the -visual option.
-donta[llownegcoords]
Don't allow panning into the negative region of the canvas. The default is to
allow panning in the negative region.
-dontshowb[alloons]
Prevents xfig from popping up the information balloons. See also -showballoons.
-dontshowl[engths]
Don't show lengths of lines as they are being drawn. This is the default.
-dontshowz[erolines]
Don't show axis zero lines on the canvas. The default is to show them.
-dontsw[itchcmap]
Prevents xfig from switching to a private colormap if there aren't enough colors
available in the default colormap. See also -max_image_colors.
-enc[oding] encoding
Encode character set using encoding when exporting LaTeX text. The default is 1.
This is used for the ISO-8859 encoding of character sets. Allowed values are 0 (no
encoding), 1 (ISO-8859-1) or 2 (ISO-8859-2).
-exportL[anguage] language
Specifies the default language to be used for when exporting a fig file. Choices
are:

---------------------------------------------------------------
-export_m[argin] width
Set the size of the border margin around the figure for exporting to bitmap,
PostScript, Encapsulated PostScript, or HTML MAP formats. This is in units of
points (1/72th inch). The default is 0.
-fli[pvisualhints]
Flip left/right mouse indicator messages for mice whose buttons have been switched.
The default is to NOT flip the messages.
-flu[shleft]
Set the print option to print the figure flush left. The default is to center the
figure on the page.
-free[hand_resolution] resolution
Set the resolution of the freehand drawing mode to resolution pixels. This is the
number of pixels the mouse must move before xfig adds another point to the object
being drawn.
-geom[etry] [WxH][+X+Y]
You may use the -geometry option or resource to size and/or position the xfig
window, or you may use -pwidth and/or -pheight to specify the canvas size in inches
or centimeters. If you use the -geom option to make the xfig window smaller than
the default, you may have to use the -but_per_row option to tell xfig to put 3 or 4
buttons per row on the left mode panel.
-gh[ostscript] postscript-interpreter
Select the PostScript (tm) interpreter of your choice. The default is ghostscript
(gs). This is needed when importing Encapsulated PostScript files.
-grid_c[olor] color
Draw the grid on the canvas in this color (default: red).
-grid_u[nit] unit
Only used when in inches mode to choose between showing fractions or decimal inches
in the rulers and grid. Any of the following may be used to force decimal inches:
"ten", "tenth", "10, "1/10". If any other value is used for this option, the
rulers will show 1/16 inch divisions.
-hidd[entext]
Start xfig with the hidden text mode for text objects. The Hidden attribute is
used for figures that will be used with LaTeX and is applicable only to the display
of the document in xfig. It means that the text itself is not shown onscreen, but
only the string ``<text>''. This is to keep long sequences of LaTeX formatting
commands from making the screen messy and hard to read. The default for the Hidden
flag is off.
-dontshowd[epthmanager]
Hide the depth manager panel. The default is to show the panel.
-icon_[view]
Show the library objects as icons. This is the default. The other mode is
-list_view.
-iconG[eometry] +X+Y
Specifies the position for the icon.
-im[age_editor] editor
Specify bitmap editor to use when ``Edit Image'' button is pressed in Picture
Object panel.
-inc[hes] (or-imperial)
Make inches the unit of choice. This is the default.
-ins[tallowncmap]
Install own colormap. Normally, xfig uses the current colormap.
-internalBW width
Use lines of width width between all buttons and panels (default = 1).
-international
Switch on international support (mainly Japanese and Korean), users of ISO Latin 1
(ISO-8859-1) probably should not use this, therefore the international support is
switched off by default for locales using ISO-8859-1* codesets. For all other
locales this option is already used by default.
-jpeg[_quality] quality
Set the quality factor for exporting to the jpeg format. The default is 75.
-k[eyFile] compose-key-file
Use compose-key-file instead of CompKeyDB for compose (meta) key database. If
there are no ``/''s in the name, the file must reside in the xfig library
directory, $XFIGLIBDIR, usually /usr/local/lib/X11/xfig. If there are any ``/''s
in the name it is taken as is (not relative to $XFIGLIBDIR). If there is a leading
``~/'' in the string then the ``~'' is expanded to the user's home directory.
-lan[dscape]
Make xfig come up in landscape mode (10.5" x 8"). This is the default; however as
the orientation is stored with Fig files, when you load a Fig file the orientation
will change as required. This is only true for files of version 3.0 or higher.
See also -portrait.
-lat[exfonts]
Start xfig with LaTeX font selection. Normally, the PostScript fonts are available
as the default. This flag selects the LaTeX fonts to start.
-le[ft]
Change the position of the side panel window to the left of the canvas window.
This is the default.
-library_d[ir] directory
Specify directory where Fig object libraries are located. There may be sub-
directories there and sub-sub-directories, etc.
-library_i[con_size] size
Specify the size of the icons shown for library objects. The default is 60 pixels,
with the minimum being 40 and the maximum being 120.
-lis[t_view]
Show the library objects as a list of names. The default mode is -icon_view.
-mag[nification] mag
Set export and print magnification in %.
-max[_image_colors] numcols
Limit the number of colors used for imported images to numcols (default 64).
-me[tric]
Make centimeters the unit of choice. The option -centimeters may also be used.
After xfig is started you may change the units from metric to imperial or vice
versa from a popup menu available by pressing mouse button 3 in the units box where
the two rulers meet.
-mo[nochrome]
Use black and white only.
-mu[ltiple]
Sets multiple page mode for print or export. See also -single.
-noo[verlap]
When exporting in multiple page mode, causes no overlap from page to page. This is
the default. See also -overlap.
-nor[mal] font
Cause the font used for the message window to be font. This font is also used on
the canvas when the selected font is not available in an X11 font (default = 6x13).
-nosc[alablefonts]
Disables use of the X11R5 or OpenWindows scalable fonts. You might want to use
this for debugging.
-nosp[lash]
Don't show the startup splash screen. The default is to show it ( -splash ).
-not[rack]
Turn off cursor (mouse) tracking arrows.
-nowrite_bak
When saving a drawing into an existing .fig file xfig will first rename that file
by appending ".bak" to the name. This option disables this feature.
-ov[erlap]
When exporting in multiple page mode, causes overlap from page to page of about
10%. See also -nooverlap.
-pag[eborder] color
Draw the page border on the canvas in this color (default light blue). The page
border is turned on by the -showpageborder option (resource Fig.showpageborder),
and shows the edges of the current export paper size.
-pap[er_size] size
Set the initial paper size for Export and Print. Choices are
Option Paper Size

---------------------------------
Note that this doesn't affect the size of the drawing canvas. Use the -pheight and
-pwidth options for that.
-ph[eight] height
Make the xfig canvas height high (where height is either cm or in, depending on the
-metric setting).
-po[rtrait]
Make xfig come up in portrait mode (8.5" x 9"). See note about landscape mode.
-pw[idth] width
Make the xfig canvas width wide (where width is either cm or in, depending on the
-metric setting).
-righ[t]
Change the position of the side panel window to the right of the canvas window
(default: left).
-rigi[d]
Start xfig with the rigid text mode for text objects. The Rigid attribute forces
text to remain the same size even if inside a compound object that is scaled up or
down. The default is off.
-ru[lerthick]
Set the height(width) of the top(side) rulers in pixels. The default (and minimum)
is 24.
-scala[blefonts]
Allows use of the X11R5 or OpenWindows scalable fonts (this is the default). If
the scalable fonts aren't available xfig will automatically switch to non-scaling
fonts.
-scale_factor scale
Scale every figure read in by this value. This is useful in conjunction with the
-update option to do batch scaling of figures.
-showa[llbuttons]
Show all the xfig indicator buttons instead of only those relevant to the current
drawing mode. Normally, the buttons line width, area-fill, grid mode, text size,
etc. are only visible when they are relevant to the current drawing mode. The
-showallbuttons option makes all of the indicator buttons visible at all times.
This takes up more screen real estate, but allows the user to see all settable
parameters.
-showb[alloons]
Forces xfig to pop up the information balloons when the mouse passws over a button.
This is the default. See also -dontshowballoons .
-showd[epthmanager]
Show the depth manager panel. This panel lets one show or hide objects at various
depths. This is the default.
-showl[engths]
Makes xfig show the lengths of lines being drawn, in red text near the line itself.
Also, when points are moved or added. In addition, imagine a triangle formed with
the line segment as the hypotenuse, and a vertical and horizontal line forming the
other two sides. These lines and their lengths are also drawn in red as the point
is moved or added. This mode is ignored when drawing in freehand mode.
This flag may be toggled by pressing <Meta>i (default).
-shown[ums]
With this option, xfig will draw all objects with a red number next to each vertex.
This is generally only useful for debugging.
-showp[ageborder]
Makes xfig show the border of the current paper size in the color specified by the
-pageborder option (default: light blue).
-showz[erolines]
Show axis zero lines on the canvas. This is the default
-si[ngle]
Sets single page mode for print or export. This is the default. See also
-multiple.
-sm[ooth_factor] factor
Enable smoothing when exporting to the bitmap formats (e.g. GIF, PNG, etc.). The
allowed values are 0 (no smoothing), 2 or 4 (most smoothing). This parameter is
passed to ghostscript in the -dTextAlphaBits -dGraphicsAlphaBits options to smooth
the figure.
-spec[ialtext]
Start xfig with the TeX text mode for text objects. This means that characters
that have a special meaning to TeX/LaTeX, e.g., '$' or '\', are not quoted but left
untouched in the text string. This is most useful for writing LaTeX equations. If
this flag is not set, then the backslash character '\' is changed to the \backslash
command, a brace '{' is turned into a brace command \{, etc.
-spel[lcheckcommand] command
Use command for the external spell checking program when using the spell
check/search/replace popup. The string command should include the string ``%s''
which is replaced by a temporary filename. Default is ``spell %s''.
-spinner_d[elay] msec
The delay (in milliseconds) before the spinner will automatically count up or down
when the button is pressed. Spinners are the (numeric) text widgets with an up-
and down-arrow, which when clicked, cause the value to be incremented/decremented.
The default is 500 milliseconds.
-spinner_r[rate] msec
The rate (in milliseconds) at which the spinner will count when the up- or down-
arrow is pressed.
-startfi[llstyle] stylenumber
Set the starting fill style for area fill (-1 to 21).
-startfo[ntsize] pointsize
Set the default font size for text objects (default = 12pt).
-startg[ridmode] modenumber
Set the starting grid mode (0 to 3). Mode 0 is no grid. In imperial (inches)
mode, grid mode 1 is 1/4 inch, mode 2 is 1/2 inch and mode 3 is 1 inch. In metric
mode, grid mode 1 is 2mm, mode 2 is 5mm and mode 3 is 1cm.
-startla[texFont] font
Set the starting font name for LaTeX fonts.
-startli[newidth] width
Set the starting line width.
-startpo[snmode] modenumber
Set the starting point positioning mode (0 to 4) In imperial (inches) mode,
positioning mode 0 is ``any'', mode 1 is 1/16 inch, mode 2 is 1/4 inch, mode 3 is
1/2 inch and mode 4 is 1 inch. In metric mode, mode 0 is ``any'', mode 1 is 1mm,
mode 2 is 5mm, mode 3 is 10mm and mode 4 is 20mm.
-startp[sFont] font
Set the starting font name for PostScript fonts.
-startt[extstep] stepsize
Set the starting text step.
-ta[blet]
Specifies that xfig should use the input tablet instead of the mouse for drawing.
You must have the XInputExtension in your X server and an input tablet for this to
work. Also, you must modify the Imakefile to include the USETAB and TABLIB
variables.
-track
Turn on cursor (mouse) tracking arrows (default).
-tran[sparent_color] color_number
Make the transparent color for GIF export color_number. This number is the color
number according to the xfig color panel, starting at 0 (black) and ending at 31
(gold), or may be a user-defined color number, which is 32 or higher.
-update file [ file ... ]
Run xfig in an "update" mode, where it will read each Fig file specified on the
command line and write it out to the original file, in the current file format for
the version of xfig being run. The original Fig file will be preserved with the
suffix .bak attached to the name.
In this mode, xfig doesn't connect the X server, so no window is opened, and it
exits when finished.
-users[cale] scale
Set the multiplier for displayed line lengths etc. This factor is multiplied by
the actual length, radius or diameter of the object currently being drawn on the
canvas. It is useful for making scale drawings, where e.g. 1 inch = 1 foot
(userscale = 12.0) or 1cm = 1m (userscale = 100.0).
-useru[nit] units
The units string is printed with the length information when drawing objects. For
example if the userscale = 1.0 and the userunit = ft then a line which is 3 inches
long on the canvas would be displayed as ``length = 3 ft'' when it is being drawn.
After xfig is started you may change the userscale and the userunit from a popup
menu available by pressing mouse button 3 in the units box where the two rulers
meet.
-visual visualname
Use visualname as the visual for xfig. The names are TrueColor (case is not
important), StaticColor, DirectColor, StaticGray, GrayScale and PseudoColor. xfig
uses the default visual unless this is specified. Your server must support the
desired visual. Use xdpyinfo to see what visuals and depths are supported. See
also the -depth option.
-write_bak
When saving a drawing into an existing .fig file xfig will first rename that file
by appending
-zoom zoomscale
Set the starting zoom scale.

BUGS and RESTRICTIONS
Please send bug reports, fixes, new features etc. to:
thomas.loimer@tuwien.ac.at
Because of the difference of some fonts in some X servers and the PostScript fonts on
printers, text alignment can be problematic.
Not all operations employ smart redrawing of objects which are altered as a by product of
the operation. You may need to use Redraw in these cases.
If the image is panned or the xfig window iconified and de-iconified during the middle of
an operation (e.g. while drawing a line), the picture will be distorted. This can be
corrected using Redraw after the operation is complete.
When zoomed very large, the length of dashes in dashed lines will top out at 255 pixels
long. This is due to a restriction in X that the dash list is defined by char (255 pixels
maximum for a dash). The figure will print correctly, however.
When you do a copy/rotate with multiple copies, only the creation of the last object can
be undone with the Undo button.
Modifications to text using the popup search/update/replace/spell check panel cannot be
undone.

Version 3.1:
The only difference between protocol version 3.0 and version 3.1 is that the position
of the ``magnet'' has been shifted by 14 fig units. In the 2.1 and older versions of
xfig the grid was in multiples of 5 fig units, but they were on intervals 4, 9, 14,
19, etc. When version 3.0 was created, coordinates were simply multiplied by the
ratio of the resolutions (1200/80 = 15) so values like 4 became 60 instead of 74
((4+1)*15 - 1).
The JPEG import/export code uses the Independent JPEG Group software (see jpeg/README
for details)
Image browser, editor and screen capture features by:
Jim Daley (jdaley@cix.compulink.co.uk)
Version 3.2:
The changes to the version 3.2 file protocol are the addition of the paper size,
print/export magnification, single/multiple page indicator and a transparent color
name used for GIF export to the header of the file.
The other difference in the version 3.2 protocol is the mathematical model used for
splines. The new version uses X-splines which allows the user to mix interpolation and
approximation points in a same curve. More precisely, it means that an X-spline curve
is neither an interpolated spline nor an approximated one, it is BOTH (the behaviour
of each point is controlled by one single parameter called ``shape factor''). For
additional information about X-splines, see:
"X-Splines: A Spline Model Designed for the End User"
by C. Blanc and C. Schlick, Proceedings of SIGGRAPH'95
http://dept-info.labri.u-bordeaux.fr/~schlick/DOC/sig1.html
Caveat: Because previous spline models (quadratic B-splines and Bezier with hidden
points) are no longer supported, curves that are present in version 3.1 and older
files are automatically converted to X-splines. This translation is only an
approximation process. It means that the converted curves are not exactly the same as
the original ones. Though they are usually very close, some hand-fitting may be needed
in some pathological cases.
Inclusion of X-splines by:
Carole Blanc (blanc@labri.u-bordeaux.fr)
Christophe Schlick (schlick@labri.u-bordeaux.fr)
Note: the initial implementation was done by C. Feuille, S. Grosbois, L. Maziere and
L. Minihot as a student practice (Universite Bordeaux, France).
