- XFIG - Facility for Interactive Generation of figures under X11
- ===============================================================
-
-
- Xfig is a menu-driven tool that allows the user to draw and manipulate objects
- interactively in an X window. The resulting pictures can be saved, printed
- on postscript printers or converted to a variety of other formats (e.g. to
- allow inclusion in LaTeX documents).
-
- This file contains some notes about installing xfig, the directory
- 'Examples' contains some example figures and the 'Doc' directory contains
- some further documentation including the manual in troff -man format.
-
- Please report any bugs, fixes, contributions, etc. to:

- Brian V. Smith (bvsmith@lbl.gov)

- ===================
- INSTALLATION NOTES:
- ===================
-
- 1. Edit the Imakefile if you need to customize it (see following notes)
- 2. Type "make Makefile" or "xmkmf" if you have xmkmf
- 3. Type "make install" (if you don't do this step, be sure to install resources)
- 4. Type "make install.man"
- 5. For X11R5 color implementations, specify "*customization: -color" in your
- .Xdefaults or .Xresources file.
- NOTE: this only works under X11R5.
-
- If your system doesn't have the signal SIGBUS, add the flag -DNO_SIBGUS in the
- Imakefile DEFINES line.
- If your system doesn't have strstr(), add the flag -DNOSTRSTR in the Imakefile
- in the DEFINES line.
- If your system doesn't have strtol(), add the flag -DNOSTRTOL in the Imakefile
- in the DEFINES line.
- If you are running on an IBM RS/6000 with AIX 3.2, add the flag -DDPS in the
- Imakefile and uncomment the line that says
- LOCAL_LIBRARIES = -ldps XawClientLibs
- and you will see the full PostScript object when using EPS objects.
-
- The maximum width of the top ruler is set to 1020 pixels and the height of the
- side ruler to 860 pixels. If your server can handle pixmaps larger than this
- and you need longer/taller rulers, you may set the maximum allowed in your
- Imakefile with -DMAX_TOPRULER_WD=1160 (or whatever value you wish) and
- -DMAX_SIDERULER_HT=1024 (or whatever value you wish).
-
- The SMOOTHMOTION option toggles between two methods for tracking the
- cursor. The first way (SMOOTHMOTION) just uses the (x,y) information given
- in the X pointer motion event. If your display server doesn't implement
- motion compression this is very slow for large movements of the mouse
- pointer because X sends back lots of small movement events, each of which
- causes the rubberband box to be erased and redrawn. The alternative
- way (not SMOOTHMOTION) queries the position of the X cursor whenever
- a motion event is received and if you make a large movement and then
- stop actually turns out to involve less work even though the XQueryPointer
- call is quite slow.
- The SMOOTHMOTION method is also automatically used for OpenWindows (when the
- -DOPENWIN flag is used in the Imakefile DEFINES line).
-
- ----------------------
- Printing your figures:
- ----------------------
-
- The program to translate your figure into one of many printer languages
- (Postscript, LaTex, etc) is called fig2dev and is part of the TransFig
- package by Micah Beck.
- It is available from export.lcs.mit.edu in /contrib/transfig.tar.Z or
- ftp.cs.cornell.edu in the directory /pub/fig.
- See the man pages for more information.
-
- -----------------
- OpenWindows users
- -----------------
-
- Openwindows has scalable fonts so xfig must be compiled with the -DOPENWIN
- flag in order to handle this. Also, there is a difference in the way the
- pointer position is queried for OpenWindows. See the SMOOTHMOTION description.
-
- There is also a bug in OpenWindows 2.0 which relates to pixmaps in widgets.
- You must compile xfig with the -DOPENWIN_BUG option in the Imakefile DEFINES
- line for this problem.
-
- ----------------------------------------------
- Possible problems encountered installing xfig:
- ----------------------------------------------
-
- PROBLEM:
- On a DEC Alpha the compiler may complain about something like: ".mask
- must have pcreg from .frame set if any bits are set in .mask or .fmask"
- in the file u_bound.c.
-
- POSSIBLE CAUSE AND SOLUTION:
- Set the optimization level to -O1 at least for that file.
- ________________________________________________________________________________
- PROBLEM:
- On Sun machines the linker may give erroneous error messages about
- the following symbols being undefined:
-
- ld: Undefined symbol
- _get_applicationShellWidgetClass
- _get_wmShellWidgetClass
-
- This may be ignored as it is a problem with the Sun shared libraries
- and the way X11 builds the shared Xmu library. It doesn't affect the
- operation of xfig.
- ________________________________________________________________________________
- PROBLEM:
- The window oscillates and fights with the window manager when
- I click on a mode button or try to resize the xfig window.
-
- POSSIBLE CAUSE AND SOLUTION:
- Perhaps the following resource has been set
- *allowShellResize: true
- because another program requires it to be true.
- Change the resource to be specific to the programs which need it,
- or set the following resource:
- Fig*allowShellResize: false
- Note: this is in the Fig.ad file that comes with xfig, which is
- installed when you do a "make install".
- ________________________________________________________________________________
- PROBLEM:
- Openwindows sometimes loses track of xfig's icon.
-
- POSSIBLE CAUSE AND SOLUTION:
- Cause unknown, here is a temporary kludge. Place the line:
- Fig*iconPixmap: ..../your_lib_area/fig.icon.X
- in your .Xdefaults file and copy fig.icon.X into your lib area.
- ________________________________________________________________________________
- PROBLEM:
- I can't seem to get a single xfig binary to work under both
- openwindows and standard X.
-
- POSSIBLE CAUSE AND SOLUTION:
- You can compile xfig so that it knows about openwindows fonts
- but then it won't work under standard X. If you want a single
- binary, compile with -DOPENWIN_BUG but not -DOPENWIN. This
- will work on both systems but you won't be able to access the
- openwindows fonts.
- ________________________________________________________________________________
- PROBLEM:
- When compiling on an HP 750 running HP-UX 8.05, the compiler dies with
- a bus error in the file u_undo.c.
-
- POSSIBLE CAUSE AND SOLUTION:
- There is a bug in the HP compiler. Workaround the problem by adding
- an extra statement between two statements in u_undo.c:
-
- Original:
-
- undo_glue()
- {
- list_delete_compound(&objects.compounds, saved_objects.compounds);
- tail(&objects, &object_tails);
-
- New:
-
- undo_glue()
- {
- list_delete_compound(&objects.compounds, saved_objects.compounds);
- >>> /* HP-UX 8.05 compiler bug fix -- don't ask */
- >>> last_action = last_action;
- tail(&objects, &object_tails);
- ________________________________________________________________________________
- PROBLEMS:
- o Ellipses are rotated in the wrong direction when printing.
-
- o When exporting a figure to Encapsulated Postscript, it always
- comes out in Portrait mode even if you select Landscape.
-
- o When batching together several figures and printing as one file,
- only the first one prints.
-
- POSSIBLE CAUSE AND SOLUTION:
- Get the newest version of TransFig (version 2.1.5 or later).
- ________________________________________________________________________________
- PROBLEMS:
- On HP machines, the capitalization of some letters in the text window
- in the edit popup for text objects are wrong.
-
- POSSIBLE CAUSE AND SOLUTION:
- Make sure that the CompKeyDB file has the lowercase letter definitions
- BEFORE the uppercase definitions. This should be the case for the
- CompKeyDB file shipped with xfig 2.1.5 and later.
