NAME xfig - Facility for Interactive Generation of figures under X11
SYNOPSIS xfig [ options ] [ file]
DESCRIPTION Xfigis a menu-driven tool that allows the user to draw and manipulate objects interactively under the X Window System . It runs under X version 11 release 4 or higher and requires a two- or three-button mouse . file specifies the name of a file to be edited . The description of objects in the file will be read at the start of xfig.
When using a two-button mouse use the key and the right button at the same time to effect the action of the middle button.
Xfigis available via anonymous ftp from ftp. x. org in /contrib/applications/drawing**tools/xfig.
The TransFig package is used when printing or exporting the output from xfig. It is automatically called by xfigas a back-end processor 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 an Encapsulated PostScript output.
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 -L[ andscape] 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 .
-P[ ortrait] Make xfigcome up in portrait mode (8 . 5" x 9 " ) . See note about landscape mode .
-bg color Use color as the background color for the canvas and buttons .
-bol[ d] font Cause the font used for displaying the file name and confirmation messages to be font (default = 8x13bold) .
-butt[ on] font Cause the font used for most buttons to be font (default = 6x13) .
-but**[ per **row] number Specify the number of buttons wide the mode panel should be . This is useful in conjunction with the -pheight parameter to reduce the canvas height for small screens .
-de[ bug ] Turn on debugging mode . Prints various debugging messages like font names etc .
-do[ ntswitchcmap] Prevents xfig from switching to a private colormap if there aren't enough colors available in the default colormap . See also -maximagecolors.

-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 window 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 = 6x13) .
-not[ rack] Turn off cursor (mouse) tracking arrows.
-ph[ eight] height Make the xfig canvas height high (where height is either cm or in, depending on the -metric setting) .
-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 xfigwill automatically switch to non-scaling fonts.
-nosc[ alablefonts] Disables use of the X11R5 or OpenWindows 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 .

-startp[ sFont] font Set the starting font name for PostScript fonts.
-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 .
-te[ xtoutline] Specifies that xfig will draw a red (on color machines) outline of the ``actual'' bounding box of text objects . This is not very useful anymore . In the past it was useful to show you the outline of rotated text since xfigdidn't display rotated text then.
-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, PICTURE, 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 . 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 . The accelerator 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 .
Delete ALL Delete all objects from the canvas window (may be undone) . The accelerator d will also perform this function.
Undo Undo the last object creation, deletion or modification . The accelerator 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 r and l.
Paste Paste the object previously copied into the cut/paste file into the current figure (at its original position) . The accelerator t will also perform this function.
File Pressing mouse button 3 on this button invokes Save function without popping up the file panel . Mouse button 1 or fpops 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 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 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 .

XFIG ( 1 ) USER COMMANDS XFIG ( 1 )
These two editable AsciiTextWidget s 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 r will rescan the current directory .
Cancel Pressing this button or c will pop down the File panel without making any changes to the directory or file name .
Save Pressing this button or 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 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 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 . Xfignow 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 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 . The figure will be offset by the amounts specified (Fig units) in the X and Y load/merge offset widgets . Any user-defined colors 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 several formats. Pressing mouse button 3 on this button invokes Export function without popping up the export panel . Mouse button 1 or 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, or the orientation 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. Export OffsetThese two editable AsciiTextWidget s allow one to export a figure with an offset . The figure will be offset by the amounts specified (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 negative value in the Y offset will shift the figure up. These offsets are in addition to any centering done with the centering option .
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 X11 Bitmap as the output language . The bitmap(pixmap) is created from the figure, the size of which is determined by the enclosing rectangle of all the figure plus a small border . The figure may also be saved as an color X11 pixmap (using the XPM3 package) by choosing X11 Pixmap as the output language . Finally, the figure may be saved as a GIF file. The pixmap 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.

Note that the figure that is printed is what you see on the canvas, 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. Xfigwrites the figure to a temporary file to do this. The name of the file is XFIGTMPDIR/xfig-printPID, where XFIGTMPDIRis the value of the environment variable by that name and PID is the process ID of xfig. If the environment variable XFIGTMPDIRis empty or not set, the /tmp directory is used . Print FIGURE to Batch Pressing this button or 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 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/d ecreased 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 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 (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 .
ROTATIONANGLE The rotation angle for rotating objects may be set/increased/d ecreased 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/d ecreased with this

button.
NUMBEROF POLYGON SIDES The number of sides used in creating a REGULAR POLYGON is set with this button.
NUMBEROF COPIES The number of copies to make when doing a COPY & ROTATE function on an object . Each copy will be rotated an additional ROTATIONANGLEangle from the previous . NOTE: The undo command will only undo the last of the objects created .
NUMBEROF X (or Y) COPIES The number of copies to make in the X (or Y) direction when doing a COPY function on an object . NOTE: The undo command will only undo the last of the objects created .
SMART-LINKSMODE 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 POLYLINElinks 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 . )
VERTICALALIGN This sets the vertical alignment mode for the ALIGNbutton 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 VERTICALALIGN indicator settings are used together to align objects inside a compound or in canvas .
HORIZONTALALIGN This sets the horizontal alignment mode for the ALIGNbutton in the editing mode panel . The choices are no horizontal alignment, align to left edge, middle or right edge of compound, distribute the centres or edges evenly, or abut the horizonaal edges together . The HORIZONTALALIGN and VERTICAL ALIGN indicator settings are used together to align objects inside a compound or in canvas .
ANGLEGEOMETRY 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 .
LATEXLINE 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] .
LATEXVECTOR 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 .
FILLSTYLE This button allows the user to select the area fill darkness (grey scale or color intensity) or fill patterns for all objects except TEXTand 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: 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
FILLCOLOR 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 button 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'' 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 hexadecimal 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 window. 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 .
LINEWIDTH 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 .
LINESTYLE 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 .
JOINSTYLE Lines may be joined with a miter , rounded or bevel joint . This is only used for POLYLINEor POLYGON objects .
CAP STYLE The ends of lines may be capped with butt , round or projecting cap . This is only used for POLYLINE, SPLINEor OPEN ARC objects .
ARROW MODE This button selects the auto-arrow mode for drawing lines . The options are no arrow heads, backward-pointi ng 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, SPLINEor OPEN ARC objects .
ARROW TYPE There are four types of arrows which may be filled with white or the object color .
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 justification.
TEXT SIZE The text size may be set/increased/d ecreased with this button. The default is 12 points .
TEXT STEP The interline spacing of text may be set/increased/d ecreased with this button. The number displayed gives the multiple of the font height that will be placed between lines on hitting . 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. xfiguses 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 offunless 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 POLYLINEbutton, 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 . 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 .
PICTURE OBJECT (PIC) This has been changed from the previous (2 . 1) version to be more generic, allowing GIF files, X11 bitmap (monochrome) files and X11 pixmap (XPM3) color files in addition to Encapsulated PostScript files to be imported . In the future, more formats will be included . 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 .
A Floyd-Steinberg dithering is applied to color images for monochrome displays .
For EPS files, xfig will attempt to use Ghostscript to generate a color image if xfig is running on an color display . Ghostscript must be compiled with with the " gif8 " and " pbmraw" drivers. The pbm driver is used when you run xfig on a monochrome display and the gif8 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 -maximagecolors ) . Whenever a new color image is added to the canvas, the colors for all the images on the canvas are reallocated 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 corner . 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 PostScript file there is no preview bitmap pressing DONE will pop down the edit panel and the word 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. 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 .
INTERPOLATEDSPLINE Create (cubic spline) spline objects . Enter control vectors in the same way as for creation of a POLYLINEobject . At least three points (two control vectors) must be entered . The spline will pass through the entered points .
POLYLINE
Sun Release 4. 1 Last change: Release 3 . 1( . 3) (Protocol 3 . 1) 14
XFIG ( 1 ) USER COMMANDS XFIG ( 1 )
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 POLYLINEexcept 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 INTERPOLATEDSPLINE 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 .
SPLINECreate (quadratic spline) spline objects . Enter control vectors in the same way as for creation of a POLYLINEobject . 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 key. If 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 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
Sun Release 4. 1 Last change: Release 3 . 1( . 3) (Protocol 3 . 1) 17
XFIG ( 1 ) USER COMMANDS XFIG ( 1 )
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 .
BREAKCOMPOUND 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 VERTICALALIGNand HORIZONTALALIGNindicators . Note that alignment with respect to the canvas 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 distributing 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 .
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 SPLINEobjects (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 ELLIPSEobjects, mouse may also be clicked on their circumferences) . The object will be
Sun Release 4. 1 Last change: Release 3 . 1( . 3) (Protocol 3 . 1) 18
XFIG ( 1 ) USER COMMANDS XFIG ( 1 )
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 variable is empty or not set then /tmp is used .
DELETEPOINTS 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 .

* Encapsulated PostScript picture objects don't use any of the above attributes. The PostScript image is self-defined . However, X11 bitmap picture objects use the pen color for coloring the bitmap image .
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 .
FLIPVERTICALLY 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 .
FLIPHORIZONTALLY 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 .
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 to any angle and will be displayed at any angle now. Older versions of xfig (before 2 . 1 . 8) could only display horizontal and vertical text (2 . 1 . 7) or horizontal only (before 2 . 1 . 7) .

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 .
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 DEFINESline . For example, to have a maximum top ruler width of 1160 pixels, add -DMAX**TOPRULER **WD=1160 to your DEFINESline in the Imakefile .
If the image is panned or the xfig window iconified and de-iconified during the middle of an operation (e . g . while drawing a line), the picture will be distorted . This can be corrected using Redraw after the operation is complete .
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 .
See the README file for troubleshooting .

Version 3. 1:
The only difference from version 3 . 0 to version 3 . 1 is that the position of the " magnet " has been shifted by 14 fig units. In the 2 . 1 and older versions of xfig the grid was in multiples of 5 fig units, but they were on intervals 4, 9, 14, 19, etc . When version 3 . 0 was created, coordinates were simply multiplied by the ratio of the resolutions (1200/80 = 15) so values
