XFIG(1)XFIG(1)NAMExfig - Facility for Interactive Generation of figures under X11
SYNOPSISxfig [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 ver‐
sion 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.
For a HTML-based xfig reference guide, see the Help menu in xfig or
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 via anonymous ftp from ftp://ftp.x.org/contrib/appli‐
cations/drawing_tools/xfig and usually from ftp://epb1.lbl.gov/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 out‐
put:
LaTeX fig2dev -L latex translates xfig to LaTeX picture envi‐
ronment commands which can be processed along with other
LaTeX commands.
Metafont fig2dev -L mf produces Metafont output.
PostScript fig2dev -L ps produces an Encapsulated PostScript output.
fig2dev -L tk produces a tk output. This is for the
tcl/tk tool command language/tool kit package. Canvas
objects are generated from the Fig primitives and a
toplevel canvas is created.
Bitmaps fig2dev can also convert Fig to GIF, JPEG, PCX, PNG, PPM,
TIFF (no compression), XBM, XPM, and AutoCAD Slide.
IBM-GL fig2dev -L ibmgl produces a IBM-GL (HP/GL) output.
Pic fig2dev -L pic produces a pic output.
PiCTeX fig2dev -L pictex produces PiCTeX output. This contains
macros that can be used with the PiCTeX environment under
TeX or LaTeX.
Others fig2dev has options for these other languages: box, epic,
eepic, and eepicemu.
The TransFig package is available via anonymous ftp from ftp.x.org in
/contrib/applications/drawing_tools/transfig.
OPTIONS-help
Print all command-line options for xfig and quit.
-bal[loon_delay] msec
Cause popup information balloons to be delayed by msec millisec‐
onds. The default is 500 milliseconds.
-bol[d] font
Cause the font used for displaying the file name and confirma‐
tion 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

-------------------------------------------
-fl[ushleft]
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.
-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.

= 1).
-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 EPS, GIF, JPEG, PCX or XPM
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.
-pa[per_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).
-ri[ght]
Change the position of the side panel window to the right of the
canvas window (default: left).
-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 rele‐
vant 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 visi‐
ble 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 -dontshow‐
balloons.
-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 draw‐
ing in freehand mode.
This flag may be toggled by pressing <Meta>i (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 spe‐
cially 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 file‐
name. Default is ``spell %s''.
-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.
-tr[ack]
Turn on cursor (mouse) tracking arrows (default).
-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.
GRAPHICAL OBJECTS
The objects in xfig are divided into primitive objects and compound
objects. The primitive objects are: ARC, CIRCLE, ELLIPSE, POLYLINE,
POLYGON, PICTURE, BOX, ARC-BOX, CLOSED SPLINE, OPEN SPLINE, and TEXT.
A primitive object can be moved, rotated, flipped vertically or hori‐
zontally, scaled, copied, aligned within a compound object or erased.
The TEXT primitive may not be flipped. The attributes of any primitive
object can be edited using a popup panel (discussed below), so you can,
for instance, set the position of an object manually.
A compound object is composed of primitive objects. The primitive
objects that constitute a compound can not be individually modified,
but they can be manipulated as an entity; a compound can be moved,
rotated, flipped vertically or horizontally, scaled, copied or erased.
A compound that contains any boxes or arc-boxes may only be rotated by
90 degrees.
Objects may overlap other objects according to their ``depth''.
Objects with larger depth number are obscured by objects with smaller
depth.
Regular polygons may be created using a special drawing mode, but a
general POLYGON is created as a result, which may then be modified,
i.e. the individual vertices may be moved if desired. Conversions
between POLYLINE , POLYGON , OPENSPLINE and CLOSEDSPLINE are achieved
by the CONVERT tool.
DISPLAY REGIONS
There are ten regions in the xfig window: the command region, top
ruler, side ruler, drawing mode, editing mode, filename, message, mouse
function indicator, canvas (drawing area), and indicator region with
buttons to show and change settings such as line thickness, line style,
color, etc. (The mouse function indicator region was inspired by the
UPS debugger from the University of Kent.) The drawing and editing
mode regions may be placed (together) to the left or right of the the
canvas region (default: left).
In addition, when the mouse passes over certain buttons or regions
there are ``balloons'' (messages) which popup to indicate the function
of the area under the mouse. These may be turned on and off by click‐
ing on the button labelled ``Balloons'', to the right of the message
region. There is a check mark indicating their state.
COMMAND PANEL FUNCTIONS
Quit Exit from xfig, discarding the figure. If the figure has been
modified and not saved, the user will be asked to confirm the
action, by clicking mouse button 1 on a confirm/cancel popup
menu. The accelerator <Meta>q will also perform this function.
This and all other accelerators are defined in the app-defaults
file and may be changed if desired.
Port/Land
Change shape of xfig canvas from/to portrait/landscape. Note:
the canvas will automatically change to the portrait/landscape
configuration specified in Fig files of version 3.0 or higher
when loading those files.
New Delete all objects from the canvas window and erase current file
name to make a new drawing (may be undone). The accelerator
<Meta>n will also perform this function. If you attempt to save
the new figure using the keyboard accelerator <Meta>s or with
mouse button 3 on the File button the popup file menu will
appear for you to enter a file name.
You may use the accelerator <Meta>d to delete all the objects
from the canvas and retain the current file name.
Undo Undo the last object creation, deletion or modification. The
accelerator <Meta>u will also perform this function. If an undo
of a Paste or file Merge is done, any user-defined colors in the
figure pasted in or the file just merged will NOT be undefined.
Redraw Redraw the canvas. There are also two accelerators which do a
redraw — <Meta>r and <Ctrl>l.
Paste Paste the object previously copied into the cut/paste file into
the current figure. The object will appear on the canvas under
or near the mouse where it may then be moved and placed by
pressing mouse button 1. The accelerator <Meta>t will also per‐
form this function.
File Pressing mouse button 3 on this button invokes Save function
without popping up the file panel. Before the figure is saved
the original file is first renamed with the suffix ``.bak''
appended. This provides a backup file.
Mouse button 1 or <Meta>f pops up a panel which contains several
file-related functions. Do not use this function for importing
images (picture objects). See the ``IMPORTING PICTURE OBJECTS''
section.
Current Filename
This is read-only AsciiTextWidget which contains the filename
that will be used to write output to a file if there is no name
specified in the Filename panel.
Filename
This is an editable AsciiTextWidget which contains the filename
selected either by clicking on a filename from the Alternatives
list or by typing a name in directly. Pressing return in the
Filename window will Load the file and copy the name to the Cur‐
rent Filename widget.
Note that xfig will automatically uncompress or gunzip any files
that have .Z, .z or .gz as the suffix.
(File) Alternatives
Pressing mouse button 1 on a filename in the file alternatives
window will copy the filename into Filename window and show a
preview of the figure in the file. It also shows the size of
the figure in its drawing units (in or cm). Pressing return in
this window will Load the file specified in the Filename window
(if any) or the Current Filename widget.
Filename Mask
A wildcard mask may be typed into this editable AsciiTextWidget
to restrict the search of filenames to a subset ala the ls com‐
mand. Pressing return in this window will automatically rescan
the current directory. This string may be set by setting the X
toolkit resource Fig*file_panel*mask*string.
Current Directory
This is an editable AsciiTextWidget which shows the current
directory. It may be modified by the user to manually set a
directory name. When return is pressed in this window the
directory specified is scanned for files matching the File‐
namemask, if any.
The ~ (tilde) character may be used to specify a user's home
directory, ala unix shell tilde expansion.
(Directory) Alternatives
Pressing mouse button 1 on a directory name in the directory
alternatives list will do a ``change directory'' to that direc‐
tory.
Pressing mouse button 3 in either the file or Directory Alterna‐
tives window will do a ``change directory'' to the parent direc‐
tory.
Load/Merge figure offset
These two editable AsciiTextWidgets allow one to load or merge a
figure with an offset on the canvas. The figure will be offset
by the amounts specified (in Fig units) in the X and Y panels.
A negative value in the X offset will shift the figure to the
left, and a negative value in the Y offset will shift the figure
up.
Home Pressing this button will change the directory to the $HOME
directory of the user.
Rescan Pressing this button or <Meta>r will rescan the current direc‐
tory.
Cancel Pressing this button or <Meta>c will pop down the File panel
without making any changes to the directory or file name.
Save Pressing this button or <Meta>s will save the current contents
of the canvas in the file specified in the Filename window if
any, or the name specified in the Current Filename if the former
is empty. If the filename being saved is different from the
current figure name and that file already exists a confirmation
popup menu will appear asking the user to confirm or cancel the
save. If there is a filename in the Filename window it is
copied to the Current Filename window.
The current Export directory is updated to the current File
directory when Save is pressed.
Before the figure is saved the original file is first renamed
with the suffix ``.bak'' appended. This provides a backup file.
Load Pressing this button or <Meta>l will clear the canvas of any
current figure and read the figure from the filename specified
in the Filename menu item if any, or the name specified in the
Current Filename if the former is empty. The figure will be
offset by the amounts specified (Fig units) in the X and Y
load/merge offset widgets. If there is a figure currently on
the canvas and any modifications have been made to it and not
saved, a popup query window will first appear asking if the user
wishes to discard the current figure or cancel the Load opera‐
tion.
The current Export directory is updated to the current File
directory when Load is pressed.
Note that xfig will automatically uncompress or gunzip any files
that have .Z, .z or .gz as the suffix.
A popup message window will appear and diagnostic messages will
be written if xfig changes any ``illegal'' object values to
legal values. For example, older versions of xfig were lax
about initializing unused parts such as depth, and would produce
very large, random values. Xfig now will ``clean up'' bad val‐
ues and inform you when it does so. Also, if you read in an
older file format, xfig will inform you that it is converting it
to the current format for that version of xfig.
This window can be popped down by clicking the mouse button on
the Dismiss button.
Merge Pressing this button or <Meta>r will read the figure from the
filename specified in the Filename window if any, or the name
specified in the Current Filename if the former is empty, and
merge it with the figure already on the canvas. It is first
made into a compound object so it may be easily moved later.
The figure will be offset by the amounts specified (Fig units)
in the X and Y load/merge offset widgets. Any user-defined col‐
ors in the file being merged will be renumbered if necessary to
unique values so as not to conflict with any user-defined colors
already defined. There is no comparison of the color values of
the existing user-defined colors with the colors being merged in
so there may be identical colors with different numbers.
See Load above for a description of the popup message window.
Export Will let you export the figure to an output file in one of sev‐
eral formats. Pressing mouse button 3 on this button invokes
Export function without popping up the export panel.
Mouse button 1 or <Meta>e pops up a directory browser widget and
a menu with several export-related functions:
Magnification
This is an editable AsciiTextWidget which contains the magnifi‐
cation to use when translating figure to the output language.
The default is 100%.
Fit to Page
Pressing this button will set the magnification so that the fig‐
ure will just fit the current paper size with no less than a 1/2
inch margin.
Fig Size:
This label shows the figure size at the current magnification.
It is updated when the panel is popped up and when the user
changes the magnification and shows the size in inches or cm
depending on the current units.
Paper Size
This is a pulldown menu which allows you to select the paper
size for printing. The 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)
Orientation
This button will toggle the output orientation between Landscape
(horizontal) and Portrait (vertical). The default orientation
is the same as the mode that xfig was started with, or the ori‐
entation in the Fig file when loading a Fig file of version 3.0
or higher.
Justification
This window will only be sensitive when the language selected is
``ps'' (PostScript). You may choose that the figure is flush
left or centered in the output file.
Pages With this pulldown menu you can select whether the figure should
be exported as a single page or multiple pages. The multiple
page option would only be useful if the figure is larger than
the current physical paper size.
Export Offset
These two editable AsciiTextWidgets allow one to export a figure
with an offset. The figure will be offset by the amounts speci‐
fied (in inches or cm) in the X and Y panels. A negative value
in the X offset will shift the figure to the left, and a nega‐
tive value in the Y offset will shift the figure up. These off‐
sets are in addition to any centering done with the centering
option.
Language
The translation language to use for xfig output. The default is
specified in the resource Fig.exportLanguage and is Encapsulated
PostScript as xfig is distributed.
Several languages are available; PostScript, Encapsulated Post‐
Script, LaTeX, TPIC, PIC, Textyl, IBM/GL (HP/GL), MetaFont, and
serveral bitmap formats; GIF, JPEG (JFIF), PNG, PCX (PC Paint‐
brush), ACAD (AutoCad slide), TIFF (no compression), tk
(tcl/tk), PPM (Portable Pixmap package), XBM (X11 monochrome
bitmap) and XPM (XPM3 package, producing color pixmaps).
Image quality (%)
For JPEG(JFIF) export, this entry will appear, and you may
select the quality factor for the JPEG image. Valid values are 1
to 100%. The default quality of 75% seems to be fine for fig‐
ures containing only solid objects (no images) and adequate for
figures containing imported images (GIF, JPEG, etc.).
Transparent Color
For GIF export, this menu button will appear and you may choose
that one of the colors in the figure is ``transparent'', meaning
that for those GIF viewers that support transparent color (Net‐
scape, for example) that color will not appear in the figure.
Instead, the background of the viewer will show through in place
of that color
The default is ``None'' (no transparent color).
Default Output Filename
This is read-only AsciiTextWidget which contains the filename
that will be used to write output to a file if there is no name
specified in Output File. The default is the figure name plus
an extension that reflects the output language used, e.g.
myfigure.ps if PostScript is the current language used. If the
file already exists a confirmation popup menu will appear asking
the user to confirm or cancel the save.
Output Filename
This is an editable AsciiTextWidget which contains the filename
to use to write output to a file. Pressing return in this win‐
dow will Export the file and copy the name to the Default Output
Filename widget. If the file already exists a confirmation
popup menu will appear asking the user to confirm or cancel the
save.
(File) Alternatives
Pressing mouse button 1 on a filename in the file alternatives
window will select that file by copying the filename into File‐
name window. Pressing return in this window will Export the
file and copy the name to the Default Output Filename widget.
Filename Mask
A wildcard mask may be typed into this editable AsciiTextWidget
to restrict the search of filenames to a subset ala the ls com‐
mand. Pressing return in this window will automatically rescan
the current directory. This string may be set by setting the X
toolkit resource Fig*export_panel*mask*string.
Current Directory
This is an editable AsciiTextWidget which shows the current
directory. It may be modified by the user to manually set a
directory name. When return is pressed in this window the
directory specified is scanned for files matching the File‐
namemask, if any.
It is automatically updated to follow the current File directory
when a File Load or Save is done.
The ~ (tilde) character may be used to specify a user's home
directory, ala unix shell tilde expansion.
(Directory) Alternatives
Pressing mouse button 1 on a directory name in the directory
alternatives list will do a ``change directory'' to that direc‐
tory.
Pressing mouse button 3 in either the file or Directory Alterna‐
tives window will do a ``change directory'' to the parent direc‐
tory.
Home Pressing this button will change the directory to the $HOME
directory of the user.
Rescan Pressing this button or <Meta>r will rescan the current direc‐
tory.
Cancel Pressing this button or <Meta>c will pop down the Export menu
without doing any print operation.
Export Pressing this button or <Meta>e will write (export) the figure
to the file using the selected language. If the file already
exists, a confirmation window will popup to ask the user to con‐
firm the write or cancel. Pressing return in the Output File‐
name window will also Export the file.
Print Pressing mouse button 3 on this button invokes Print to Printer
function without popping up the print panel. Pressing the Shift
key and mouse button 3 invokes the Print to Batch function.
Pressing mouse button 1 or <Meta>p pops up a menu with several
print-related functions:
Magnification
This is an AsciiTextWidget which contains the magnification to
use when translating figure to the output language.
Fit to Page
Pressing this button will set the magnification so that the fig‐
ure will just fit the current paper size with no less than a 1/2
inch margin.

This label shows the figure size at the current magnification.
It is updated when the panel is popped up and when the user
changes the magnification and shows the size in inches or cm
depending on the current units.
Paper Size
This is a pulldown menu which allows you to select the paper
size for printing. See the Export menu for the paper sizes.
Orientation
This button will toggle the output orientation between Landscape
(horizontal) and Portrait (vertical). The default orientation
is the same as the mode that xfig was started with, or the ori‐
entation in the Fig file when loading a Fig file of version 3.0
or higher.
Justification
This button will bring up a sub-menu from which you may choose
center or flush left to justify the figure on the page. The
default is flush left.
Pages With this pulldown menu you can select whether the figure should
be printed as a single page or multiple pages. The multiple
page option would only be useful if the figure is larger than
the current physical paper size.
Printer
This is an AsciiTextWidget which contains the printer to use if
output is directed to a printer. The name of the printer may be
set setting the X toolkit resource Fig*printer*string. If no
resource is set, the environment variable PRINTER is used.
Print Job Params
This is an AsciiTextWidget which into which you may put any
extra command-line parameters that your lpr or lp program needs
for printing. If the meta sequence %f appears in the string the
current figure name will be substituted. It may appear more
than once. This may be set using the resource
Fig*job_params*string.
Figures in batch
This indicator shows how many figures have been put in the batch
file for printing
Dismiss
Pressing this button or <Meta>c will pop down the Print menu.
Print FIGURE/BATCH to Printer
Pressing this button or <Meta>p will send the current figure (or
the batch file if it is has any figures in it) to the printer,
by passing it through fig2dev to convert it to PostScript then
to the unix lpr (on BSD equivalent Unixes) or lp (on SYSV sys‐
tems) program. If the batch file is printed by this button then
it is removed after printing. The message in the button changes
to reflect whether the batch file will be printed (when there
are any figures in the batch file) or the current figure.
Note that the figure that is printed is what you see on the can‐
vas, not necessarily the figure file. I.e., if you haven't
saved the figure since the last changes, the figure from the
canvas is printed. Xfig writes the figure to a temporary file
to do this. The name of the file is XFIGTMPDIR/xfig-printPID,
where XFIGTMPDIR is the value of the environment variable by
that name and PID is the process ID of xfig. If the environment
variable XFIGTMPDIR is empty or not set, the /tmp directory is
used. Print FIGURE to Batch Pressing this button or <Meta>b
will append the figure (in PostScript form) to a batch file.
The Print to Printer button will send the batch file to the
printer.
Clear Batch
Pressing this button or <Meta>x will erase the accumulated fig‐
ures from the batch file.
Help The Help button pulls down a menu to view various help informa‐
tion.
The first entry will launch an external HTML browser specified by the
Fig.browser resource to view the xfig html reference manual written by
T. Sato. netscape is the default browser.
The next entry will launch an external PDF viewer specified by the
Fig.pdfviewer resource to view the Xfig How-to Guide written by Peter
Hiscocks. acroread is the default viewer.
The third entry will launch an external PDF viewer to view the xfig pdf
man pages. However, the HTML pages are much better.
The last entry will popup a window showing the xfig version and copy‐
right information.
INDICATOR PANEL COMMAND DESCRIPTIONS
The indicator panel contains buttons to set certain drawing parameters
such as line thickness, canvas grid, rotation angle etc. All of the
buttons use the same mouse buttons for setting values. Pressing mouse
button 1 on the indicator will pop up a panel in which either a value
may be typed (e.g. for a line thickness) or the mouse may be clicked on
one of several buttons (e.g. for grid style or font name). For those
that expect a value, pressing return in the value part of the window
will set the new value and pop down the menu.
Pressing mouse button 2 on an indicator will decrement the value (e.g.
for line thickness) or cycle through the options in one direction (e.g.
font names), while pressing mouse button 3 will increment the value or
cycle through the options in the other direction.
ZOOM SCALE
The canvas zoom scale may be set/increased/decreased with this
button. The zoom scale is displayed within the zoom button.
Ruler, grid and linewidth are scaled, too.
Pressing mouse button 1 will popup a panel where the zoom amount
may be entered manually. There is also a checkbox that if
checked, will force zooming with the mouse to use integral zoom
values (e.g. 2, 3, 4).
Pressing mouse button 2 will decrease the zoom factor by 1.0
unless it is less than 1.0 already in which case it will reduce
to the nearest 0.25.
Pressing mouse button 3 will increase the zoom factor by 1.0
unless it is less than 1.0 in which case it will increase it to
the nearest 0.25.
Pressing the control key and mouse button 3 together will set
the zoom scale to 1.
The figure may also be zoomed by defining a zoom rectangle on
the canvas by pressing the Control key and mouse button 1
together. This will define one corner of the zoom rectangle.
Move the mouse and click mouse button 1 again to define the
opposite corner of the zoom rectangle. If the ``Integral area
zoom'' checkbox in the zoom popup is checked, the area will be
zoomed by an integral value (e.g. 2, 3, 4).
GRID MODE
With this button the user may select no grid, 1/4 inch (5mm in
metric mode) grid 1/2 inch (10mm) grid, or 1 inch (20mm).
POINT POSITION
This button controls the coarseness of object placement on the
canvas. The options are exact (on pixel) placement, 1/16 inch
(1mm in metric mode), 1/4 inch (5mm), 1/2 inch (10mm) or 1 inch
(20mm). This allows the user to easily place objects in hori‐
zontal or vertical alignment.
This also restricts which objects may be ``picked up'' by the
mouse when editing. If a corner of an object is not positioned
on the canvas on a multiple of the point positioning resolution
you may not be able to pick it. If this happens, a black square
will temporarily appear above the mouse cursor. This square
will also appear anytime the user tries to pick a nonexistent
object.
ROTATION ANGLE
The rotation angle for rotating objects may be
set/increased/decreased with this button. Note that not all
objects may be rotated, and certain objects may only be rotated
by certain angles. Pressing mouse button 2 will decrease the
angle in steps of 15 degrees, while mouse button 3 will increase
the angle the same amount. To select other angles, press mouse
button 1 and enter the angle in the popup menu.
DEPTH The depth at which new objects will be created may be
set/increased/decreased with this button.
NUMBER OF POLYGON SIDES
The number of sides used in creating a REGULAR POLYGON is set
with this button.
NUMBER OF COPIES
The number of copies to make when doing a COPY & ROTATE function
on an object. Each copy will be rotated an additional ROTATION
ANGLE angle from the previous.
NUMBER OF X (or Y) COPIES
The number of copies to make in the X (or Y) direction when
doing a COPY function on an object.
SMART-LINKS MODE
This button controls the smart-links mode. When turned on,
lines which link box-like objects together (henceforth called
links) are treated specially when one of the box-like objects is
moved or copied. For a copy, the link is also copied. When set
to MOVE mode, the end point of the link which touches (or is
very near) the perimeter of the box is moved with the box so
that the box and the end point remain linked. When set to SLIDE
mode, the end segment of the link slides so that the box remains
linked and the angle of the end segment is maintained. This is
useful for keeping the last segment of a link horizontal or ver‐
tical.
(At the moment, smart-links only work for the MOVE and COPY
functions and only works for POLYLINE links and box-like
objects. Another limitation at the moment is that if both ends
of a link touch the box being operated on, only one end of the
link will be adjusted.)
VERTICAL ALIGN
This sets the vertical alignment mode for the ALIGN button in
the editing mode panel. The choices are no vertical alignment,
align to top edge, middle or bottom edge of compound, distribute
the centres or edges evenly, or abut the vertical edges
together. The HORIZONTAL ALIGN and VERTICAL ALIGN indicator
settings are used together to align objects inside a compound or
in canvas.
HORIZONTAL ALIGN
This sets the horizontal alignment mode for the ALIGN button in
the editing mode panel. The choices are no horizontal align‐
ment, align to left edge, middle or right edge of compound, dis‐
tribute the centres or edges evenly, or abut the horizontal
edges together. The HORIZONTAL ALIGN and VERTICAL ALIGN indica‐
tor settings are used together to align objects inside a com‐
pound or in canvas.
ANGLE GEOMETRY
The following settings are available to restrict the drawing
angle of line segments in POLYLINES, POLYGONS and SPLINES.
UNRESTRICTED
Allow lines to be drawn with any slope. This is the default
setting.
LATEX LINE
Allow lines to be drawn only at slopes which can be handled by
LaTeX picture environment lines: slope = x/y, where x,y are
integers in the range [-6,6].
LATEX VECTOR
Allow lines to be drawn only at slopes which can be handled by
LaTeX picture environment vectors: slope = x/y, where x,y are
integers in the range [-4,4].
MANHATTAN-MOUNTAIN
Allow lines to be drawn in the horizontal, vertical or diagonal
direction only.
MANHATTAN
Enforce drawing of lines in the horizontal and vertical direc‐
tion only. The name Manhattan comes from the horizontal/verti‐
cal look of the Manhattan (New York City) skyline.
MOUNTAIN
Enforce drawing of only diagonal lines. The name comes from the
pointed shape of mountains.
FILL STYLE
This button allows the user to select the area fill darkness
(grey scale or color intensity) or fill patterns for all objects
except TEXT and PICTURE, or to turn off area fill altogether.
There are 21 ``shades'' going from black to full saturation of
the fill color, and 21 more ``tints'' from full saturation + 1
to white. In addition, there are 16 patterns (currently only
available for PostScript, GIF, JPEG, PNG, PCX, ACAD, TIFF, TK,
PPM, XPM and XBM output):
30 degree left-leaning diagonal lines,
30 degree right-leaning diagonal lines,
30 degree crosshatch,
45 degree left-leaning diagonal lines,
45 degree right-leaning diagonal lines,
45 degree crosshatch,
bricks,
circles
horizontal lines,
vertical lines,
90 degree crosshatch,
fishscales,
small fishscales,
octagons,
horizontal ``sawtooth'' and
vertical ``sawtooth''.
PEN COLOR
This button is used to select one of 32 standard colors for the
borders of objects, or one of the user-defined colors
FILL COLOR
This button is used to select one of 32 standard colors or user-
defined color to fill objects with if they have a fill style.
Pressing mouse button 1 on either the fill or pen color buttons
will popup an extended color panel, allowing the user to select
either a standard color or a user-defined color from menus.
The 32 standard colors are black, yellow, white, gold, five
shades of blue, four shades of green, four shades of cyan, four
shades of red, five shades of magenta, four shades of brown, and
four shades of pink.
To select one of the standard colors either click mouse button 1
on the desired color and either press Return or click mouse but‐
ton 1 on the ``Ok'' button. The latter step will pop down the
color panel. You may also double click mouse button 1 on the
desired color to select it and pop down the color panel in one
step.
To add a user-defined color press mouse button on the ``Add
Color'' button in the ``User Defined Colors'' section. User
defined colors are assigned values sequentially starting from 32
for a maximum of 512 colors.
A user color may be deleted by pressing mouse button 1 on the
color box to select it and then pressing the ``Del Color'' but‐
ton.
The last color deleted may be undeleted by pressing the ``UnDel
Color'' button.
To edit a user color first select the color square by pressing
mouse button 1 on the desired square. A solid or dashed line
will be drawn around the box to show that it is selected. Then
choose the color either by using the RGB (red, green, blue) or
the HSV (hue, saturation, value) sliders or by typing a hexadec‐
imal value into the window under the pen or fill color boxes
representing the red, green and blue components (00 to FF). If
the latter is used, typing carriage return in the hexadecimal
window will set the color.
Additionally, there is a button above each of the RGB sliders
which when activated will ``lock'' two or more sliders together
at their current setting and allow you to increase or decrease
their values together with the ``lock'' slider.
If the user color being edited was just created, a dashed line
will be drawn around the box instead of a solid line to indicate
that it is new. The color that is currently in the pen or fill
boxes will be copied into the user color cell for modification.
In this way you may start with a standard color or other user
color and modify it from there.
The user color is said to be ``defined'' when any of the sliders
is moved or a carriage return is typed into the hexadecimal win‐
dow. This will be shown by a solid line being drawn around the
square instead of dashed.
The pen or fill color choice is activated when the panel is
popped up by the respective button in the indicator panel, but
you may switch to editing the other color by pressing either the
``Edit Pen'' or ``Edit Fill'' button.
Note that TransFig supports color output for PostScript. On
monochrome screens the objects are created with the selected
color, but black (or white) is used to draw the objects on the
canvas.
LINE WIDTH
The width of lines may be selected with this button. Zero width
lines may be drawn for the purpose of having filled areas with‐
out outlines.
LINE STYLE
The choices for line style are solid, dash, dot, dash-dot, dash-
dot-dot and dash-dot-dot-dot. Once created, a dashed or dotted
line may be edited to change the length of dashes or the spacing
of dots respectively. The dash length and dot gap can be
changed from the default using the popup menu.
JOIN STYLE
Lines may be joined with a miter, rounded or bevel joint. This
is only used for POLYLINE or POLYGON objects.
CAP STYLE
The ends of lines may be capped with butt, round or projecting
cap. This is only used for POLYLINE, SPLINE or OPEN ARC
objects.
ARROW MODE
This button selects the auto-arrow mode for drawing lines. The
options are no arrow heads, backward-pointing arrow head, for‐
ward-pointing arrow head or both. If one or both arrow head
modes are turned on, then arrow heads are automatically drawn
when drawing POLYLINE, OPEN SPLINE or OPEN ARC objects.
ARROW TYPE
There are four types of arrows which may be filled with white or
the object color.
ARROW SIZE
Clicking mouse button 1 here will popup a panel where you may
set the arrow head thickness, width and height (length) either
as absolute values or as multiples of the current line thick‐
ness. Check the box labelled ``Absolute Values'' to use abso‐
lute values (the default) or the box labelled ``Multiple of Line
Width'' to use that feature. The values to change are under
their respective check boxes. The arrow measurements are in the
same units as line widths (1/80 inch). This has changed from
earlier versions where the width and height were in Fig units.
Clicking on mouse buttons 2 or 3 here will cycle through dis‐
playing the current thickness, width, and height settings.
BOX CURVE
The radius of the corners on ARC-BOX objects may be set with
this button.
TEXT JUSTIFICATION
The adjustment of text may be set to left, center or right jus‐
tification.
TEXT SIZE
The text size may be set/increased/decreased with this button.
The default is 12 points.
TEXT STEP
The interline spacing of text may be set/increased/decreased
with this button. The number displayed gives the multiple of
the font height that will be placed between lines on hitting
<return>. The default is a factor of 1.2 times the current font
size.
TEXT FONT
This button allows a selection of 35 fonts available for most
Apple PostScript printers. There are two buttons at the top of
the menu. The cancel button pops down the menu without changing
the current font. The use latex fonts will switch the menu to
the LaTeX font choices. When the LaTeX font menu is up, besides
a cancel button there is a button to switch back to the Post‐
Script fonts.
The name of the font is printed in the font itself so that one
may see what that font looks like. If a corresponding X11 font
exists, new text is created on the canvas using that font. xfig
uses the size of X11 font closest to that selected by the font
size button. If the X11 font doesn't exist, xfig uses the font
selected by the -normal option. To abort selection of a font,
click mouse button 1 on cancel.
TEXT FLAGS
This button displays the current setting of the text flags. You
may use mouse buttons 2 and 3 to step back and forth through the
three flag settings: Hidden, Rigid and Special. To change any
of the flags you must use mouse button 1 to popup a menu from
which you may change any or all of the flags.
The Hidden flag 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.
The Special Special flag means that special characters in the
string are not specially processed but are passed directly to
LaTeX. 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. The default for the Special flag
is off unless xfig is started with the command-line parameter
-specialtext (resource specialtext).
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.
DRAWING AND EDITING MODE PANELS
Icons in the drawing and editing mode panel windows represent object
manipulation functions, modes and other drawing or modification aids.
Manipulation functions are selected by positioning the cursor over the
icon representing the desired drawing/editing function and clicking
mouse button 1. The selected icon is highlighted, and a message
describing its function appears in the message window. The hilighting
remains on until another function is selected.
DRAWING MODE PANEL COMMAND DESCRIPTIONS
The drawing mode panel contains buttons used to create the various xfig
objects. Once the drawing mode is selected, the object is created by
moving the mouse to the point on the canvas where the object is to be
placed and pressing and releasing mouse button 1. After that the mouse
is moved to the second point and mouse button 1 is again pressed for
the next point. For those objects which may have more than two points
(e.g. a line), mouse button 1 may be pressed for each successive point,
and mouse button 2 must be pressed to finish the object. If the cap
style is rounded, the point object will be a filled circle. Newly cre‐
ated points may be deleted by pressing the shift key and mouse button
1. For the ARC object, which requires exactly three points mouse but‐
ton 1 is used for all three points.
At any time mouse button 3 may be pressed to cancel the creation of the
object.
ARC Create an arc. Specify three points using mouse button 1. The
first and last points will form the endpoints of the arc and the
second specifies any point on the arc. There are two types of
arcs, open and pie-wedge.
BOX Create rectangular boxes. Start by clicking mouse button 1 on
any corner of the desired box and finish with the same mouse
button on the diagonally opposite corner of the box.
ARC-BOX
Create rectangular boxes with rounded corners. Start and finish
with mouse button 1 in the same way as BOX. The radius of the
corners is selected by the BOX CURVE button.
CIRCLE Create circles by specifying their radii or diameters. Click
mouse button 1 on the center of the circle and drag the mouse
until the desired radius or diameter is attained. Click mouse
button 1 again to finish the circle.
ELLIPSE
Create ellipses using the same procedure as for the drawing of
circles.
IMPORTING PICTURE OBJECTS
The following picture types may be imported into a figure:
· Encapsulated PostScript files
· GIF files
· JPEG (JFIF) files
· PCX (PC Paintbrush)
· X11 bitmap (monochrome) files
· X11 pixmap (XPM3) color files
Compressed (.Z) and gzipped (.z or .gz) files are also handled.
You must have the XPM3 libraries installed to use the XPM
import/export features. See the README and Imakefile files.
As it says, you may now import Fig (xfig) files as picture
objects. These may not be edited, but may be scaled and
rotated.
Import is by reference for all picture types. This means that
the picture file is not copied into the Fig file, only the pic‐
ture file name is stored with the Fig file.
A Floyd-Steinberg dithering is applied to color images for mono‐
chrome displays.
For EPS files, xfig will attempt to use Ghostscript to generate
a color image if xfig is running on an color display. Ghost‐
script must be compiled with with the ``pcx256'' and ``pbmraw''
drivers. The pbm driver is used when you run xfig on a mono‐
chrome display and the pcx256 driver is used on a color display.
Ghostscript is available from prep.ai.mit.edu.
A neural network color allocation scheme is used when the number
of colors for all the color images on the canvas exceeds the
lesser of the number of free colorcells or the value in the
resource Max_image_colors (command-line parameter
-max_image_colors). Whenever a new color image is added to the
canvas, the colors for all the images on the canvas are reallo‐
cated and the images are redrawn. No reallocation is done when
images are deleted from the canvas.
Click mouse button 1 on any corner for the PIC object and finish
by clicking mouse button 1 again on the diagonally opposite cor‐
ner. The EDIT popup panel will appear and the file name of the
PIC object may be entered. After pressing DONE or APPLY (see
the description of the EDIT panel for the difference between the
DONE and APPLY buttons) the bitmap part of the PIC object will
appear in the box just created. If no PIC file is available yet
or no name is entered or in the case of an Encapsulated Post‐
Script file there is no preview bitmap pressing DONE will pop
down the edit panel and the word <empty> or the PIC file name
will remain in the PIC box. Later, when the name of the PIC
file is known or the file is available, you may re-read the PIC
file using the popup edit panel and the bitmap part of the PIC
file will replace the name in the box.
If you want the original size of the PIC object, press the ``Use
orig size'' button and the eps bitmap will enlarge or shrink to
the size specified in the preview bitmap of the PIC file. Or,
to scale as a percentage of the original size, enter a percent‐
age value and press the ``Scale by %'' button.
If you want the PIC object to be approximately the size of the
rectangle specified with the mouse but want the aspect ratio to
be same as the original, press either ``Shrink to orig'' or
``Enlarge to orig'' buttons. You must press the APPLY button to
see these effects.
The Screen Capture button will unmap the xfig windows, allowing
you to capture either the contents of a window or a rectangular
section of the screen to a GIF* file, which becomes the current
import file. After pressing the Screen Capture button, if you
press and release mouse button 1 on a window (or the root win‐
dow) it will capture that window (without any window manager
frame). To capture a rectangular area of the screen, you press
and release mouse button 2 at one corner of the area you want to
capture, drag out the rectangle and press and release mouse but‐
ton 2 to finish. You may cancel the operation by pressing
either of the two other mouse buttons (1 or 3). The filename
given to the capture file is the base of the figure name plus
the time in seconds since 00:00:00 GMT, Jan 1, 1970 (from the
Unix time() call), e.g. myfigure_828065129.gif.
*If xfig was compiled without the USEGIF symbol then the capture
file is in PCX format (PC Paintbrush) with the suffix ``.pcx''.
The Edit Image button will call an external image viewer/editor
(see resource Fig.image_editor: in the Fig.ad file) to allow you
to edit the current image. The file is reimported automatically
after exiting the editor. The xfig windows are automatically
unmapped during the call of the editor.
The Reread button will cause xfig to re-read the image file in
case it has changed. This is useful (e.g.) when you have made
changes to the image file in a program external to xfig and you
wish to update the imported image.
The Browse button which will popup a file browser to allow you
to search directories for image files. The default search mask
will match *.gif*, *.jpg*, *.pcx*, *.xpm*, *.xbm*, *.ps* and
*.eps*. This mask is in the Fig.ad application defaults file.
POLYLINE
Create polylines (line segments connecting a sequence of
points). Enter points by clicking mouse button 1 at the desired
positions on the canvas window. Click mouse button 2 to finish.
To create a freehand line press mouse button 2 to start drawing.
As the mouse is moved points will be added to the line without
having to click the mouse buttons. To finish the freehand line
press mouse button 2 again.
For both modes, newly created points may be deleted by pressing
the Shift key and mouse button 1 before pressing mouse button 2.
The message window shows how many points have been created as
you add points to the line.
A single point object may be created by simply pressing mouse
button 3. If the cap style is rounded, the point object will be
a filled circle.
POLYGON
The function is similar to POLYLINE except that a line segment
is drawn connecting the first and last points entered.
REGULAR POLYGON
The number of sides is first selected with the NUM SIDES button
in the indicator panel. Then mouse button 1 is clicked on the
center and the mouse dragged to the desired size. The object
may be rotated as it is being created by moving the mouse up or
down relative to the starting point. Click mouse button 1 to
finish.
INTERPOLATED SPLINE
The function is similar to POLYLINE except that an open interpo‐
lated spline (a spline curve that passes through the control
points) is drawn. At least two points must be entered.
CLOSED INTERPOLATED SPLINE
The function is similar to POLYGON except that a closed interpo‐
lated spline is drawn. At least three points must be entered.
APPROXIMATED SPLINE
The function is similar to POLYLINE except that an open approxi‐
mated spline (a spline curve that passes through the two bound‐
ary points and approximates the shape of the other points) is
drawn. At least two points must be entered.
CLOSED APPROXIMATED SPLINE
The function is similar to POLYGON except that a closed approxi‐
mated spline is drawn. At least three points must be entered.
Note: xfig provides conversion tools to switch between any two
of the following objects: polylines, polygones, open interpo‐
lated spline, closed interpolated spline, open approximated
spline, closed approximated spline. This conversion can be done
either globally for the whole object (see LINE<->SPLINE and
OPEN<->CLOSED) or locally for each individual point (see EDIT
POINT).
TEXT Create text strings. Click mouse button 1 at the desired posi‐
tion on the canvas window, then enter text from the keyboard.
Text may be pasted from the PRIMARY cut buffer (xterm cut/paste
buffer) by pressing the F18 function key (the Paste key on Sun
keyboards) or any key/button defined in the translation table
for the canvas. See the default Fig.ad file for example. Text
is drawn using the current font, font size and justification
settings.
A Control-H (backspace) will delete a character to the left of
the cursor, while the Delete key or Control-D will delete the
character to the right of the cursor. A Control-X will erase
all the text to the left of the cursor, while a Control-K will
erase all the text to the right of the cursor. The Home key or
Control-A will move the cursor to the start of the text, while
the End key or Control-E move the cursor to the end of the text.
The left arrow key or Control-B move the cursor left one charac‐
ter and the right arrow or Control-F move the cursor right one
character. Finish entering/editing text by clicking mouse but‐
ton 2 or typing the <return> key. If <return> is used, the text
pointer automatically moves to the next ``line'', a distance of
the font height times the value in the TEXT STEP button, and
text input mode is re-entered. To finish text fully, click
mouse button 2 or choose any panel button that changes modes
(e.g. box, save, etc). To edit text, click on an existing text
string with mouse button 1. Insertion of characters will take
place at that point. Or, use the popup EDIT mode to modify the
text.
Eight-bit (8-bit) characters may be entered using the meta (com‐
pose) key. For example, to create an ``a umlaut'', press and
release either the Meta key, the Alt key or the Compose key,
then the letter ``a'', then " (quote). To create a ``c
cedilla'', use <meta>c followed by comma.
When modifying text in the popup edit panel, only the Compose
key will work.
The following is a list of all special characters available
using the Meta, Alt or Compose keys:

Spell Checking and String Search in Text Objects
By pressing <Meta>h in the canvas area a popup panel will appear which
lets you search for strings in the text objects and/or do string
replacement and spell checking.
The external spell checking program can be specified by the
-spellcheckcommand command-line argument (resource Fig.spellCheckCom‐
mand). The default is the ``spell'' program. See the -spellcheckcom‐
mand description for usage details.
The ``Search/Replace/Update'' button will search all text objects for
the pattern given in the ``Search:'' entry. A panel pops up showing
any matching text objects. If the ``Replace'' button is pressed, the
matched pattern in the text objects will be replaced by the string in
the ``Replace with:'' entry. If the ``Update'' button is pressed, the
matching text objects' attributes will be updated from the current set‐
tings in the bottom indicator panel.
If the search pattern is empty all text objects will be listed. If the
Update button is pressed in that case, all text objects will be
updated.
EDITING MODE PANEL COMMAND DESCRIPTIONS
When a button in the editing mode panel is pressed, any objects that
may be affected by that editing operation will show their corner mark‐
ers. Only those objects may be affected by the particular edit mode.
In cases where two edit modes exist for one button, it may be that the
corner markers will appear for objects that may be affected by one but‐
ton but not the other.
SELECTING OBJECTS
When multiple objects have points in common, e.g. two boxes that touch
at one corner, only one object can be selected by clicking on that
point. To select other objects, hold down the shift key while pressing
mouse button 1: the markers of one object will be temporarily high‐
lighted. By repeatedly clicking mouse button 1 while holding down the
shift key, it is possible to cycle through all candidates for selection
at that point. To perform the selected action, e.g. deleting one box,
click on the point without holding down the shift key. The operation
will be performed on the highlighted object.
Note: If the mouse is not clicked near enough to an object marker or
for whatever reason xfig cannot ``find'' the object the user is trying
to select, a black square will temporarily appear above the mouse cur‐
sor.
GLUE COMPOUND
Compound objects are created by first tagging the objects to be
compounded and then pressing mouse button 3 to group the tagged
objects into a compound object. Single objects are tagged by
clicking on them with mouse button 1. A number of objects can
be tagged at once by using mouse button 2 to define the upper-
left and lower-right corners of a region enclosing the objects.
Tagged objects are shown with highlighted markers. Tagged
objects which are selected (see the SELECTING OBJECTS section
above) will be temporarily unhighlighted. There is currently no
special command to tag or untag all of the objects within a fig‐
ure. You can untag all of the objects by changing from GLUE
mode to some other mode (apart from BREAK) and back again.
BREAK COMPOUND
Break a compound object into separate component parts. Click
mouse button 1 on one of the corner markers of the compound
object or along one of the imaginary lines defining the compound
box. Clicking with mouse button 2 will achieve the same effect
but will also tag the component parts for re-gluing into a com‐
pound later (although you will not see the tags until you change
to the GLUE mode).
OPEN COMPOUND
Open a compound object temporarily for editing of its compo‐
nents. The compound object selected will be opened, and all
other objects in the figure that are not part of the compound
will disappear. You can make any changes to objects in the open
compound including adding and deleting objects. If you delete
all the objects in the compound, the compound will be removed
entirely.
A popup panel with two buttons appears which lets you close the
compound again. The first, labeled ``Close This Compound'' will
close the currently open compound. If you open a compound
within a compound, you may close all the compounds with one step
by clicking on the second button labelled ``Close All Com‐
pounds''.
After all compounds are closed, the rest of the original figure
will reappear.
IMPORTANT NOTE: A side effect occurs when you open a compound,
delete an object in that compound, close the compound and
``undo'' the delete operation. The object you deleted will
reappear but it will not be part of the original compound any‐
more. You may use this to remove objects from a compound.
Conversely, if you delete an object from the canvas, open a com‐
pound then undo the delete of the original object, it will now
be part of the open compound.
PLACE LIBRARY OBJECT
Pressing this button will popup a library panel where you may
load a library from a list of libraries. The default library
directory is XFIGLIBDIR/Libraries which is defined in the Imake‐
file. This directory contains libraries which are defined by
sub-directories. The command-line argument -library_dir
(resource Fig.library_dir ) may be used to specify a different
directory. The choice of libraries is presented in a pull-down
menu. After choosing the library, the objects from the library
will be loaded. The status line shows how many objects or any
error messages that may occur. Once a library is loaded if you
single-click on an object name in the listbox area it will show
a preview of the object in the right side preview window. If
you double-click on one of the object names or single-click on
one and press the Select object button, this will pop down the
library panel and you will immediately see the chosen object
appear under the mouse on the canvas, where it may be dragged
around and placed by pressing mouse button 1 at the desired
location. You may place as many of these objects as you wish by
simply moving to the new location and pressing mouse button 1
each time.
If mouse button 2 is pressed, the library panel pops up again
where either a different object or library may be selected.
Pressing moust button 3 will cancel the library mode altogether.
Pressing Shift and mouse button 1 at the same time will switch
from drawing the object itself as it is dragged, to only drawing
the outline of the bounding box of the object. This second mode
is desirable on slow machines or with complex objects.
A library is simply a directory with .fig files, each containing
one library object. When xfig loads the .fig files as library
objects, it makes each one into a compound object so it may be
moved, scaled, etc. as a unit.
There are two ways to create your own libraries in xfig. For
the first method, create the file xfiglib in your home directory
(~/xfiglib). Each line of the xfiglib file contains the abso‐
lute path of the directory containing the .fig files in that
library, followed by the name of the library, which may be mul‐
tiple words with whitespace. There may be at most 50 libraries.
The length of the library name (not the path) may be at most 40
characters long, and any library may have no more than 400
objects, each of whose name (the name of the .fig file) may not
be more than 40 characters.
You must then either start xfig with `` -library_dir
~/xfiglib'', or set the resource ``Fig.library_dir: ~/xfiglib''.
Here is an example:
/xfig/Examples/Libraries/Electrical/Physical Electrical Parts
/xfig/Examples/Libraries/Electrical/Schematic Electrical Schematic Components
/xfig/Examples/Libraries/Logic Logic Symbols
/xfig/Examples/Libraries/Flowchart Flowchart Elements
/xfig/Examples/Libraries/Buildings Buildings
The other method is to use the X resource Fig.library_dir or
command-line argument -library_dir to point to a directory which
may contain Fig files (.fig) and sub-directories, each of which
may also contain .fig files and sub-directories if desired.
To link your libraries with the ones that come with xfig, simply
make a symlink for each xfig library in your library directory
or make one symlink to the top-level xfig library directory in
your library directory.
This is more versatile than using the xfiglib file because you
can add more directories in the top-level directory (or sub-
directories) and there is no need to edit the xfiglib file.
Using this method, the names of the libraries are simply the
names of the directories, e.g. if the resource Fig.library_dir:
/xfig/Examples/Libraries is defined, the /xfig/Exam‐
ples/Libraries/Electrical directory will result in the library
name Electrical.
It is hoped that users will contribute Fig objects to the
libraries to expand and enhance them for all xfig users. If you
wish to contribute any Fig objects to existing or new libraries,
please send them to me at xfigmail@epb1.lbl.gov. You may
restrict their usage by users if you wish, but all will benefit
if you allow free usage, i.e. copying, using them in published
reports, etc.
SCALE OBJECT
Any object may be scaled. If mouse button 1 is pressed on any
corner of a BOX or ARC-BOX object, then that object will be
scaled proportionally to its aspect ratio. If pressed on an
edge then that dimension will be scaled. For other objects only
mouse button 2 may be used for scaling; said object will be
scaled larger or smaller about its center. Mouse button 2 may
be used on boxes too. Text may only be scaled if inside a com‐
pound object and then only if its RIGID flag is set to NORMAL
(using the popup edit panel). See the TransFig manual for
description of text options.
ALIGN Align objects. Click mouse button 1 to align objects inside a
compound object or mouse button 2 to align all objects on canvas
according to the setting in the VERTICAL ALIGN and HORIZONTAL
ALIGN indicators. Note that alignment with respect to the can‐
vas doesn't work for distributing or abutting. The choices are
the cumulative effect of vertically aligning the objects to the
TOP, MIDDLE or BOTTOM edge and horizontally aligning to the
LEFT, MIDDLE or RIGHT edge of the compound, along with dis‐
tributing or abutting the objects vertically or horizontally.
MOVE POINT
Modify the position of a point of any object except TEXT and
COMPOUND objects. For unrestrained movement, click mouse button
1 over the desired point, reposition the point, and click the
left button again. For horizontally or vertically constrained
move, click mouse button 2 on the desired point and move either
horizontally or vertically. Notice that once you choose the
direction (horizontal or vertical), movement is constrained in
that direction. If, after moving the mouse initially, it is
moved in the other direction a greater distance than the current
position of the mouse relative to the starting point, then that
will be the new constraint direction. In other words if you
first move the mouse horizontally one inch (say) then move it
vertically 1.3 inches, the direction will switch to vertical
until any horizontal motion exceeds 1.3 inches. When the object
is positioned where desired, click mouse button 1 to place it if
that button was used to start the move (unconstrained), or mouse
button 2 (constrained) if that button was used.
ADD POINTS
Add points to POLYLINE, POLYGON, OPEN SPLINE, or CLOSED SPLINE
objects (points of a BOX can not be added or deleted). Note
that a REGULAR POLYGON is really an ordinary POLYGON, so adding
points to this object is allowed and does NOT keep the polygon
regular.
MODIFY SHAPE
This tool is activated by holding down the Control and Shift
keys in any of the EDIT modes. Clicking on a control point of a
spline object with mouse button 1 (resp. 3) decreases (resp.
increases) the shape factor of the spline at this point, while
clicking with mouse button 2 allows the user to cycle quickly
between the three basic status of a control point (i.e. approx‐
imation, sharp interpolation, smooth interpolation).
MOVE Move object. Click mouse button 1 (unconstrained move) or mouse
button 2 (constrained move) on any corner marker of the object
to be moved. The horizontal/vertical constrained movement
(mouse button 2) works exactly as described for MOVE POINT.
COPY / CUT TO CUT BUFFER
Copy object to canvas or cut buffer. Click mouse button 1
(unconstrained copy) or mouse button 2 (constrained copy) on any
corner marker of the object to be copied (for CIRCLE and ELLIPSE
objects, mouse may also be clicked on their circumferences).
The object will be duplicated and then moved exactly as in MOVE.
If the number of X or Y copies is non-zero (from the bottom
panel) then that many copies will be made in each respective
direction, spaced evenly by the amount of the distance the
object is placed from the original object.
If mouse button 3 is clicked on an object, that object is copied
to the cut buffer for pasting into this or another figure. The
file used for the cut buffer is called .xfig in the user's $HOME
directory. This allows a user to run two or more xfig processes
and cut/paste objects between them. If there is no $HOME, a
file is created in a temporary directory called xfigPID where
PID is the xfig process ID. The temporary directory used is
specified in the environment variable XFIGTMPDIR. If that vari‐
able is empty or not set then /tmp is used.
DELETE POINTS
Delete points from POLYLINE, POLYGON, OPEN SPLINE, or CLOSED
SPLINE. Objects (points of a BOX or ARC-BOX can not be added or
deleted). Note that a REGULAR POLYGON is really an ordinary
POLYGON, so deleting points from this object is allowed and does
NOT keep the polygon regular.
DELETE Click mouse button 1 on an object to delete the object. Delete
a region of the canvas by clicking mouse button 2 and dragging
the mouse to define an area of objects to delete. Clicking
mouse button 3 on an object will copy the object to the cut buf‐
fer (see COPY/CUT TO CUT BUFFER above).
EDIT OBJECT
Edit settings for an existing object. Click mouse button 1 on
the object and a pop-up menu will appear showing existing set‐
tings for the object. Some of the menu entries may be changed
by typing new values in the appropriate windows. These are
editable AsciiTextWidgets and allow cut and paste. Others pop
up a sub-menu of multiple choices when pressed and held. Yet
others are buttons which toggle a setting on or off (e.g. arrow
heads on lines). For the coordinates of an object's points, you
may enter either Fig units (1/1200 inch) or inches or centime‐
ters by following the value with an ``i'' or ``c'' respectively.
Press the ``done'' button to apply the changes to the object and
finish. Press the ``apply'' button to apply the changes but
keep the menu up for further changes. Press the ``cancel'' but‐
ton to cancel the changes and pop down the menu.
The following table shows which settings are used for the dif‐
ferent objects.

these settings.
EDIT POINT
In the EDIT OBJECT mode, click on a control point of a spline
with mouse button 3 to call the EDIT POINT window. Set the shape
factor either with the scrollbar for arbitrary values, or with
the buttons for preset values. Modifications are displayed
interactively (the fill pattern, if any, will be temporally
removed during the edition, to provide interactive rates).
UPDATE By pressing mouse button 1 on an object, the current settings
for the indicator buttons (line width, line style, area fill
etc.) which have been selected for update are copied into that
object. When xfig is started, all indicator buttons which are
components of objects are selected for update. To unselect an
indicator, click on the update button and click mouse button 1
on the small button in the upper-right corner of the indicator.
When that indicator is selected the foreground color (default
black) shows. When it is unselected the background color
(default white) shows.
If mouse button 2 is clicked on an object, the settings in the
object that are selected by the indicator buttons are copied
into those indicator button settings. Thus, one may copy
selected attributes of one object to another.
FLIP VERTICALLY
Flip the object up/down (mouse button 1) or copy the object and
flip it (mouse button 2). Point to part of the object, click
the appropriate button. That object will be flipped vertically
about that point.
Optionally, mouse button 3 may be pressed on the canvas to set
an anchor point about which the object will be flipped. A
crosshair indicates the anchor point on the canvas. Pressing
this button again will unset the anchor point.
FLIP HORIZONTALLY
Flip the object left/right (mouse button 1) or copy the object
and flip it (mouse button 2). Point to part of the object,
click the appropriate button. That object will be flipped hori‐
zontally about that point.
Optionally, mouse button 3 may be pressed on the canvas to set
an anchor point about which the object will be flipped. A
crosshair indicates the anchor point on the canvas. Pressing
this button again will unset the anchor point.
ROTATE CLOCKWISE
Rotate the object (mouse button 1) or copy and rotate it (mouse
button 2) -N degrees (clockwise), where N is the amount set in
the rotation indicator button. The object is rotated about the
chosen point.
Optionally, mouse button 3 may be pressed on the canvas to set a
rotation point about which the object will be rotated. A
crosshair indicates the rotation point on the canvas. Pressing
this button again will unset the rotation point.
Not all objects can be rotated, and not all can be rotated at
arbitrary angles. For example, BOX, ARC-BOX and PIC objects may
only be rotated by 90 degrees. Text objects may be rotated and
to any angle.
ROTATE COUNTER-CLOCKWISE
Rotate the object (mouse button 1) or copy (mouse button 2) +N
degrees (counter-clockwise), where N is the amount set in the
rotation indicator button. The object is rotated about the cho‐
sen point.
Optionally, mouse button 3 may be pressed on the canvas to set a
rotation point about which the object will be rotated. A
crosshair indicates the rotation point on the canvas. Pressing
this button again will unset the rotation point.
SPLINE <-> LINE
Click on mouse button 1 to cycle between polyline, open interpo‐
lated spline and open approximated spline when the selected
object is open, or between polygon, closed interpolated spline
and closed approximated spline when the selected object is
closed.
Click on mouse button 3 to turn an open object (polyline or open
spline) into its corresponding closed object (polygon or closed
spline) and vice versa. The closed object is opened at the
selected point.
ADD/DELETE ARROWS
Add or delete arrow heads of OPEN SPLINE, POLYLINE or ARC
objects. Add an arrow head by clicking mouse button 1 on the
endpoint of the object. Delete an arrow head by clicking mouse
button 2 on the endpoint or arrow head. The length and thick‐
ness of the arrowheads may be set using the arrow size button in
the indicator panel.
PANNING
The figure may be panned by clicking mouse button 1, 2 or 3 in the
rulers. Clicking mouse button 1 in the top ruler will pan the image to
the left by 1/2 inch (1cm in metric mode), adjusted for zoom factor.
Clicking mouse button 3 in the top ruler will pan the image right by
the same amount. By pressing and holding mouse button 2 the user may
drag the ruler by the amount desired, thus panning the image by that
amount.
If the Shift key is held down while panning the movement is five (5)
times the normal rate.
The figure is panned up and down in the same way by clicking the mouse
in the ruler on the right of the canvas.
If the Shift key is held down while panning the movement is five (5)
times the normal rate.
The figure can be returned to its origin by clicking mouse button 1 in
the units (e.g. cm or in) box.
The arrow keys may also be used to pan the image and the home key to
return the figure to the origin. Also, pressing the Control Key and
mouse button 2 will pan the figure to the origin.

BUGS and RESTRICTIONS
Please send bug reports, fixes, new features etc. to:
xfig-bugs@epb1.lbl.gov (Brian V. Smith)
Because of the difference of some fonts in some X servers and the Post‐
Script 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 Imake‐
file.
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 pic‐
ture will be distorted. This can be corrected using Redraw after the
operation is complete.
Corners of object scaled with point positioning in one of the grid
modes will not always fall on the grid line, but to the closest pixel.
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 fig‐
ure will print correctly, however.
When you do a copy/rotate or array place when making multiple copies of
objects, 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 mul‐
tiples of 5 fig units, but they were on intervals 4, 9, 14, 19,
etc. When version 3.0 was created, coordinates were simply multi‐
plied 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 soft‐
ware (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 mathemati‐
cal 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 nei‐
ther 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-fit‐
ting 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. Gros‐
bois, L. Maziere and L. Minihot as a student practice (Universite
Bordeaux, France).
