XFIG(1)

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 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/transfig.tar.Z.

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

OPTIONS

-geom[etry] WxH+X+Y
    Specifies the geometry for Fig application.

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

-ri[ght]
    Change the position of the side panel window to the right of the canvas window (default: left).

-le[ft]
    Change the position of the side panel window to the left of the canvas window.

-mo[nochrome]
    Use black and white only.

-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").

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

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

    Turn on cursor (mouse) tracking arrows (default).

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

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

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

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

-fg color
    Use color as the foreground color and default color for objects. -bg color Use color as the background color for the canvas and buttons.

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

-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).

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

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

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

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

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

-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.

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

-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.

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

-sc[alablefonts]
    Allows use of the X11R5 scalable fonts.

-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.

-fl[ushleft]
    Set the print option to print the figure flush left. The default is to center the figure on the page.

-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 show the text rotation on the canvas.

-e[xportLanguage] language
    Specifies the language to be used for when exporting a fig file. Choices are:
    Name | Language
    box | LaTeX box (figure boundary)
    latex | LaTeX picture
    epic | LaTeX picture + epic macros
    eepic | LaTeX picture + eepic macros
    eepicemu | LaTeX picture + eepicemu macros
    pictex | PiCTeX macros
    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

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). 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, arc-boxes, ellipses or circles 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
Nine regions comprise the display area of xfig: the command region, top ruler, side ruler, drawing mode region, editing mode region, message region, indicator region with buttons to set and show current line thickness, line style, color, area-fill gray color and several other settings, mouse function indicator region and canvas region. (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.

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. 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.

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 *export_panel*mask*string.

Current Directory
    This is an editable AsciiTextWidget which shows the current directory. It may be modified by the user to manually set a directory name. When return is pressed in this window the directory specified is scanned for files matching the 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 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.

Dismiss
    Pressing this button or <Meta>c will pop down the Print menu.

Print 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 File
    Pressing this button or <Meta>x will erase the accumulated figures from the batch file.

Print to Printer
    Pressing this button or <Meta>p will send the current figure (or the batch file if it is has any figures in it) to the printer, by passing it through fig2dev to convert it to PostScript then to the unix lpr (on BSD equivalent Unixes) or lp (on SYSV systems) program. If the batch file is printed by this button then it is removed after printing. 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. Xfig writes the figure to a temporary file to do this. The name of the file is XFIGTMPDIR/xfig-printPID, where XFIGTMPDIR is the value of the environment variable by that name and PID is the process ID of xfig. If the environment variable XFIGTMPDIR is empty or not set, the /tmp directory is used.

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.

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.

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 AsciiTextWidgets and allow cut and paste. Others pop up a sub-menu of multiple choices when pressed and held. Yet others are buttons which toggle a setting on or off (e.g. arrow heads on lines). 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.
    Object | †Angle | Area | Line | Line | Box | ‡Depth | Color | Radius | Text Font/
     |  | Fill | Width | Style | Curve |  |  |  | Just./Size
    Arc |  | X | X | X |  | X | X
    Arc-Box |  | X | X | X | X | X | X
    Circle | X | X | X | X |  | X | X | X
    Ellipse | X | X | X | X |  | X | X | X
    EPS |  |  |  |  |  | X | X
    Box,Polygon, | X | X | X |  | X | X
    Line,Spline
    Text | X |  |  |  |  | X | X |  | X
† The angle may be set, but the object will only be rotated on PostScript output. ‡ 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 only the markers are rotated on the screen, but the text itself is not displayed rotated 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 on the screen. They will be rotated only 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.
