NAME
xfig - Facility for Interactive Generation of figures under
X11
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 fori xfig is in an HTML-based
reference guide. See the Help menu in xfig or point your
browser at Doc/html/index.html (provided with the xfig
distribution, usually in the Doc/www directory). 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 ftp://www-epb.lbl.gov/xfig and
usually from
ftp://ftp.x.org/contrib/applications/drawing_tools/xfig .
The TransFig package is used when printing or exporting the
output from xfig. The fig2dev program from the TransFig
package is automatically called by xfig as a back-end
processor to produce various types of output:
LaTeX, Metafont, PostScript or Encapsulated PostScript, tk
(tcl/tk tool command language/tool kit package), GIF, JPEG,
PCX, PNG, PPM, TIFF, XBM, XPM, AutoCAD Slide, IBM-GL
(HP/GL), Pic PiCTeX, box, epic, eepic, and eepicemu.
See man fig2dev for all options.
The TransFig package is available from ftp://www-
epb.lbl.gov/xfig and
ftp://ftp.x.org/contrib/applications/drawing_tools/transfig
.
OPTIONS
-help
Print all command-line options for xfig and quit.
-a[llow_neg_coords]
Allow panning into the negative region of the canvas.
This is the default
-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.
-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.
-dont_a[llow_neg_coords]
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.
-dont_s[how_zero_lines]
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:
Name Language
-------------------------------------------
box LaTeX box (figure boundary)
latex LaTeX picture
epic LaTeX picture + epic macros
eepic LaTeX picture + eepic macros
eepicemu LaTeX picture + eepicemu macros
pictex PiCTeX macros
ibmgl IBMGL (or HPGL)
eps Encapuslated PostScript
ps PostScript
pdf PDF (Portable Document Format)
pstex Combined PS/LaTeX (both PS and LaTeX parts)
textyl Textyl special commands
tpic TPIC
pic PIC
mf MF (MetaFont)
cgm CGM (Computer MetaGraphics)
tk Tk (of the tcl/tk fame)
sld (AutoCad slide)
pcx PCX
png PNG
gif GIF
jpeg JPEG (JFIF)
tiff TIFF
ppm PPM (portable pixmap package)
xbm X11 Bitmap
xpm X11 Pixmap (XPM3 package)
-------------------------------------------
-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
pixels (1/80th 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.
-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.
-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.
-hide[depthmanager]
Hide the depth manager panel. The default is to show
the panel.
-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.
-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.
-li[brary_dir] directory
Specify directory where Fig object libraries are
located. There may be sub-directories there and sub-
sub-directories, etc.
-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. Also
-centimeters.
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.
-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).
-nos[calablefonts]
Disables use of the X11R5 or OpenWindows scalable
fonts. You might want to use this for debugging.
-not[rack]
Turn off cursor (mouse) tracking arrows.
-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 (resource Fig.showpageborder)
option, 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
Letter (8.5" x 11"),
Legal (8.5" x 14"),
Ledger ( 17" x 11"),
Tabloid ( 11" x 17"),
A (8.5" x 11"),
B ( 11" x 17"),
C ( 17" x 22"),
D ( 22" x 34"),
E ( 34" x 44"),
A4 (21 cm x 29.7cm),
A3 (29.7cm x 42 cm),
A2 (42 cm x 59.4cm),
A1 (59.4cm x 84.1 cm),
A0 (84.1 cm x 118.9cm),
B5 (18.2cm x 25.7cm)
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 thickness of the top and side rulers in pixels.
The default (and minimum) is 24.
-sc[alablefonts]
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.
-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).
-showp[ageborder]
Makes xfig show the border of the current paper size in
the color specified by the -pageborder option (default
light blue).
-show_[zero_lines]
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.
-spec[ialtext]
Start xfig with the special text mode for text objects.
Special text means that special characters in the
string are not specially processed but are passed
directly to LaTeX. 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 5mm, mode 2 is 1cm and mode
3 is 2cm.
-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.
-up[date] 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.
-zoom zoomscale
Set the starting zoom scale.

BUGS and RESTRICTIONS
Please send bug reports, fixes, new features etc. to:
xfig-bugs@epb1.lbl.gov (Brian V. Smith)
When reporting a bug, please first check if the problem is
mentioned in the FAQ section of the HTML files (xfig Help
menu).
If it is not mentioned there, be sure to report the
operating system you are using (e.g. SunOS 4.1.3), type of X
server and version (OpenWindows 3, X11R6.4, XFree86 3.2.2,
etc) and color depth (e.g. 8bpp, 16bpp), and most
importantly the version of xfig or fig2dev that is having
the problem.
It is also VERY useful to me if you can provide a stack
trace from a debugger such as gdb, dbx, ups, etc, if the bug
causes xfig to crash.
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.
Some servers do not allow bitmaps/pixmaps taller than the
screen height or wider than the screen width. That is why
there is a limit on the width of the top ruler and height of
the side ruler. If you need wider/taller rulers AND your
server allows bigger pixmaps, you may define MAX_TOPRULER_WD
and/or MAX_SIDERULER_HT in your Imakefile in the DEFINES
line. For example, to have a maximum top ruler width of
1160 pixels, add -DMAX_TOPRULER_WD=1160 to your DEFINES line
in the Imakefile.
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.
See the README file for troubleshooting.

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).
