NAME
xfig - Facility for Interactive Generation of figures under X11
Version 3.2.9
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. If file is given, it specifies the name of a file to be edited.
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 instead of a three-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.
-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.
-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] ghostscript executable
Specify the name or path to the ghostscript executable. The default is gs. This version of xfig
links into the ghostscript library. The ghostscript executable is not needed, it is only called
as a fallback-solution.
-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.
-ima[ge_editor] editor
Specify bitmap editor to use when ``Edit Image'' button is pressed in Picture Object panel.
-inc[hes] (or -imp[erial])
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).
-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 | file]
Specify directory or file containing directory names 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. Fig files saved
in metric mode are, due to rounding issues, scaled down by about 5% when saved, and scaled up when
read in. Using -inches or -imperial avoids the scaling.
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.
-nointernational
Switch off international support. This can be done if text objects only contain ASCII characters.
(Characters beyond ASCII are interpreted as Latin 1). If there are error messages when starting
xfig regarding "missing charsets in string to fontset conversion", setting this option avoids the
error.
-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 global settings "Show line lengths" or "Show vertex numbers" are true (default = 6x13).
-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.
-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.
-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 exits when finished, and no window is opened.
-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 the fonts shown on the canvas 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).

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.

Note: the initial implementation was done by C. Feuille, S. Grosbois, L. Maziere and L. Minihot as a
student practice (Universite Bordeaux, France).
