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 in an X window. 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 description of objects in the file will be
read at the start of xfig.

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.

The TransFig package is used to print or export the output
from xfig.

Note for previous xfig users:

The f2p and f2ps translators have been phased out because
the TransFig package from Micah Beck is a more general
purpose translator for more graphics languages. The
TransFig package can be used as a back-end processor to xfig
to produce various types of output:

LaTeX - fig2dev -L latex translates xfig to LaTeX
picture environment commands which can be
processed along with other LaTeX commands.

Postscript -
fig2dev -L ps produces a PostScript 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
export.lcs.mit.edu in /contrib/R5fixes/transfig-
fixes/transfig.2.1.X.tar.Z, where the X is the current
patchlevel.

Note: TransFig versions 2.1.4 and later support color output
for PostScript.

OPTIONS
-L[andscape]
Make xfig come up in landscape mode (10" x 8"). This
is the default.

-P[ortrait]
Make xfig come up in portrait mode (8" x 9").

-bg color
Use color as the background color for the canvas and
buttons.

-bol[d] font
Cause the font used for displaying confirmation
messages to be font (default = 8x13bold).

-bu[tton] font
Cause the font used for most buttons to be font
(default = 6x13).

-de[bug]
Turn on debugging mode. Prints various debugging
messages like font names etc.

-e[xportLanguage] language
Specifies the language to be used for when exporting a
fig file. Choices are:

l l. 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 eps Encapuslated Postscript
ps Postscript pstex Combined PS/LaTeX (PS part)
pstex_t Combined PS/LaTeX (LaTeX part)
textyl Textyl special commands tpic TPIC pic PIC
xbm X11 Bitmap

-fg color
Use color as the foreground color and default color for
objects.

-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
Specifies the geometry for Fig application.

-iconG[eometry] +X+Y
Specifies the position for the icon.

-inc[hes]
Make inches the unit of choice (default).

-me[tric]
Make centimeters the unit of choice.

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.

-internalBW width
Use lines of width width between all buttons and panels
(default = 1).

-inv[verse]
Use inverse video (white on black).

-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.

-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.

-mo[nochrome]
Use black and white only.

-nor[mal] font
Cause the font used for the message panel and ruler
numbers to be font. This font is also used on the
canvas when the selected font is not available in an
X11 font (default = fixed).

-not[rack]
Turn off cursor (mouse) tracking arrows.

-ph[eight] units
Make xfig come up units high (where units are either cm
or in).

-pw[idth] units
Make xfig come up units wide (where units are either cm
or in).

-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 scalable fonts.

-nosc[alablefonts]
Disables use of the X11R5 scalable fonts. You might
want to use this for debugging.

-sh[owallbuttons]
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.

-sp[ecialtext]
Start xfig with the special text mode for text objects.

-startf[ontsize] pointsize
Set the default font size for text objects (default =
12pt).

-startl[atexFont] font
Set the starting font name for LaTeX fonts.

-startp[sFont] font
Set the starting font name for Postscript fonts.

-te[xtoutline]
Specifies that xfig will draw a red (on color machines)
outline of the "actual" bounding box of text objects.
This is mostly useful for determining what rotated text
will look like since xfig doesn't rotate the text
(other than 0, 90, 180, or 270 degrees) on the canvas.

-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.

GRAPHICAL OBJECTS
The objects in xfig are divided into primitive objects and
compound objects. The primitive objects are: ARC, CIRCLE,
CLOSED SPLINE, ELLIPSE, POLYLINE, POLYGON, ENCAPSULATED
POSTSCRIPT, BOX, ARC-BOX, SPLINE, and TEXT.

A primitive object can be moved, rotated, flipped vertically
or horizontally, scaled, copied, aligned within a compound
object or erased. The TEXT primitive may not be flipped. It
may be rotated but only the markers show the rotation (on-
screen) for angles other than 0, 90, 180 and 270 degrees.
Text IS rotated on PostScript output. 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.

DISPLAY WINDOWS
Ten regions comprise the display area of xfig: the command
region, top ruler, side ruler, drawing mode region, editing
mode region, filename region, message region, mouse function
indicator region and canvas region, and indicator region
with buttons to set and show current line thickness, line
style, color, area-fill gray color and several other
settings. (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 window (default: left).

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.

Delete ALL
Delete all objects from the canvas window (may be
undone).

Undo Undo the last object creation, deletion or
modification.

Redraw
Redraw the canvas.

Paste
Paste the object previously copied into the cut/paste
file into the current figure (at its original
position).

File Pressing mouse button 3 on this button invokes Save
function without popping up the file panel.
Mouse button 1 or <Meta>f pops up a panel which
contains several file-related functions:

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
Current Filename widget.

(File) Alternatives
Pressing mouse button 1 on a filename in the file
alternatives window will select that file by
copying the filename into Filename window.
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 command.
Pressing return in this window will automatically
rescan the current directory. This string may be
set by setting the X toolkit resource
*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
Filenamemask, 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 directory.

Pressing mouse button 3 in either the file or
Directory Alternatives window will do a "change
directory" to the parent directory.

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 directory.

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 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.

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. 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 operation.

The current Export directory is updated to the
current File directory when Load is pressed.

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 values 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 Read
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 shown on the canvas.

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 several 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 magnification to use when translating figure
to the output language. The default is 100%.

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.

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.

Language
The translation language to use for xfig output
when output is directed to a file. The default is
PostScript. The figure may be saved as an X11
bitmap by choosing Xbitmap as the output language.
The bitmap is created from the figure, the size of
which is determined by the enclosing rectangle of
all the figure plus a small border.

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 window 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 Filename window.
Pressing return in this window will Export the
file and copy the name to the Default Output
Filename widget.

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 directory.

Pressing mouse button 3 in either the file or
Directory Alternatives window will do a "change
directory" to the parent directory.

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 directory.

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
confirm the write or cancel. Pressing return in
the Output Filename 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.

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.

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.

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 *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.

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.
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 figures from the batch file.

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 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 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.

GRID MODE
With this button the user may select no grid, 1/4 inch
(5mm in metric mode) grid or 1/2 inch (10mm) grid.

POINT POSITION
This button controls the coarseness of object placement
on the canvas. The options are exact (on pixel)
placement, 1/16 inch (2mm in metric mode), 1/4 inch
(5mm) or 1/2 inch (10mm). This allows the user to
easily place objects in horizontal 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.

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. 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
vertical.

(At the moment, this mode only works 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. 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 alignment, align to left edge, middle or
right edge of compound. The HORIZONTAL ALIGN and
VERTICAL ALIGN indicator settings are used together to
align objects inside a compound 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 direction only. The name Manhattan comes
from the horizontal/vertical 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) for all objects except TEXT and
ENCAPSULATED POSTSCRIPT, or to turn off area fill
altogether.

COLOR
The user may select one of eight predefined colors to
draw with, or select that the default (-fg) color is to
be used. The eight colors are black, blue, green,
cyan, red, magenta, yellow and white. Note that
TransFig versions 2.1.4 and later support color output
for PostScript. On monochrome screens the objects are
created with the selected color, but black 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 without outlines.

LINE STYLE
The choices for line style are solid, dashed and
dotted. 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.

BOX CURVE
The radius of the corners on ARC-BOX objects may be set
with this button.

ARROW MODE
This button selects the auto-arrow mode for drawing
lines. The options are no arrow heads, backward-
pointing arrow head, forward-pointing arrow head or
both. If one or both arrow head modes are turned on,
then arrow heads are automatically drawn when drawing
POLYLINE, SPLINE or ARC objects.

TEXT JUSTIFICATION
The adjustment of text may be set to left, center or
right justification.

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
PostScript 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 and Special attributes of text objects are
used with figures that will be incorporated into LaTeX.
Please see the documentation for LaTeX for further
information. The default for the Hidden flag is off.
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. To create a single point using the
POLYLINE button, press and release mouse button 2. For the
ARC object, which requires exactly three points mouse button
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.

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.

ENCAPSULATED POSTSCRIPT OBJECT (EPS)
Click mouse button 1 on any corner for the EPS object
and finish by clicking mouse button 1 again on the
diagonally opposite corner. The EDIT popup panel will
appear and the file name of the EPS 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 EPS object will appear in the box just created. If
no EPS file is available yet or no name is entered or
there is no preview bitmap in the EPS file, pressing
DONE will pop down the edit panel and the word <empty>
or the EPS file name will remain in the EPS box.
Later, when the name of the EPS file is known or the
file is available, you may re-read the EPS file using
the popup edit panel and the bitmap part of the EPS
file will replace the name in the box.

If you want the original size of the EPS 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 EPS file. If you want the EPS 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.

If the EPS file has no preview bitmap, but has a
%%BoundingBox comment and xfig has been compiled xfig
with the -DGSBIT flag and you have gs (ghostscript)
version 2.4 or newer then xfig will call gs to produce
a preview bitmap on the screen. Ghostscript is
available from prep.ai.mit.edu.

INTERPOLATED SPLINE
Create (cubic spline) spline objects. Enter control
vectors in the same way as for creation of a POLYLINE
object. At least three points (two control vectors)
must be entered. The spline will pass through the
entered points.

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.

POLYGON
Same as 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.

CLOSED INTERPOLATED SPLINE
Create closed or periodic splines. The function is
similar to POLYGON except that a closed interpolated
spline is drawn. The spline will pass through the
points (knots).

CLOSED SPLINE
Create closed or periodic spline objects. The function
is similar to POLYGON except that a closed spline will
be drawn instead of polygon. The entered points are
just control points; i.e. the spline will not pass any
of these points.

SPLINE
Create (quadratic spline) spline objects. Enter
control vectors in the same way as for creation of a
POLYLINE object. At least three points (two control
vectors) must be entered. The spline will only pass
through the two end points.

TEXT Create text strings. Click mouse button 1 at the
desired position 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 DEL or ^H (backspace) will
delete a character, while a ^X will erase the entire
line. Finish by clicking mouse button 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 characters may be entered using the meta
(compose) key. For example, to create an "a umlaut",
hold down the meta key while pressing the letter "a",
then press " (quote). To create a "c cedilla", use
<meta>c followed by comma. The following is a list of
all special characters available using the meta key:

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 markers. 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
button 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 highlighted. 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 cursor.

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 figure.
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 to allow manipulation of its
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 (although
you will not see the tags until you change to the GLUE
mode). You can use this feature to easily alter the
objects within a compound.

SCALE OBJECT
Any object may be scaled. If mouse button 1 is pressed
on a BOX or ARC-BOX object, then that object will be
scaled proportionally to its aspect ratio. If mouse
button 2 is pressed on any object, that object will be
scaled up or down about its center. Text may only be
scaled if inside a compound 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. 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.

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 otherwords 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.

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.

ADD POINTS
Add points to POLYLINE, POLYGON, 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.

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 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 variable is
empty or not set then /tmp is used.

DELETE POINTS
Delete points from POLYLINE, POLYGON, 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 buffer (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 settings for the object. Some of the
menu entries may be changed by typing new values in the
appropriate windows. These are editable Ascii-
TextWidgets 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).

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" button to cancel the changes and pop
down the menu.

The following table shows which settings are used for
the different objects.

- The angle may be set, but the object will only be rotated
on PostScript output for angles other than 0, 90, 180 and
270 degrees.

= The depth defines how overlapping objects are displayed.
Objects with a greater depth value are obstructed by objects
with smaller depth value. The maximum depth allowed is
1000.

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.

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 horizontally about that 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. Not all
objects can be rotated, and not all can be rotated at
arbitrary angles. For example, BOX, ARC-BOX and EPS
objects may only be rotated by 90 degrees. Text
objects may be rotated, although for angles other than
0, 90, 180 and 270 degrees only the markers are rotated
on the screen because of the limitations of the X11
Window System. Text IS rotated correctly on PostScript
output, however.

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 chosen point.

SPLINE <-> POLYLINE
Turn POLYGON into a CLOSED INTERPOLATED SPLINE object,
or turn POLYLINE into a INTERPOLATED SPLINE object.

ADD/DELETE ARROWS
Add or delete arrow heads of ARC, POLYLINE or SPLINE
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 thickness of the arrowheads may be
modified using the popup edit 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 left the 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.

The figure is panned up and down in the same way by clicking
the mouse in the ruler on the right of the canvas. Also,
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:
bvsmith@lbl.gov (Brian V. Smith)

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.

Must compile xfig with -DOPENWIN in order to make xfig
handle OpenWindows scalable fonts correctly.

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.

There is a bug in OpenWindows 2.0 which relates to pixmaps
in widgets. You must compile xfig with the -DOPENWIN_BUG
option for this problem.

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.

Rotated text will be displayed horizontally or vertically
(i.e. angles of 0, 90, 180 and 270 degrees) on the screen.
They will be rotated correctly when printed on PostScript
output.

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.
