.\" Man page portability notes
.\"
.\" These are some notes on conventions to maintain for greatest
.\" portability of this man page to various other versions of
.\" nroff.
.\"
.\" When you want a \ to appear in the output, use \e in the man page.
.\"
.\" Evidently not all versions of nroff allow the omission of the
.\" terminal " on a macro argument.  Thus what could be written
.\"
.\" .B "bold stuff
.\"
.\" in true nroffs must be written
.\"
.\" .B "bold stuff"
.\"
.\" instead.
.\"
.\" Use symbolic font names (e.g. R, I, B) instead of the standard
.\" font positions 1, 2, 3.  Ideally, do not use \f at all to change
.\" fonts (there are none in this man page at this writing).  Use the
.\" -man macros instead, that's what they are there for and they are
.\" more readable to boot.
.\"
.\" Note that sentences should end at the end of a line.  nroff and
.\" troff will supply the correct intersentence spacing, but only if
.\" the sentences end at the end of a line.  Explicit spaces, if given,
.\" are apparently honored and the normal intersentence spacing is
.\" suppressed.

.\" It's an indented paragraph starting immediately after the

.\" The reason for having this is so that we can construct the
.\" ``tag'' for the paragraph (which describes a command argument)
.\" using more than one line of -man macros.  The regular .TP
.\" macro only allows the tag to occupy one line in the source file,
.\" which can often force explicit font changes using troff mechanisms
.\" which make the source harder to read.

.SH NAME
xfig - Facility for Interactive Generation of figures under X11
.br
Version 3.2.9
.SH SYNOPSIS
.B xfig
.RI [ options ]
.RI [ file ]
.SH DESCRIPTION
.I Xfig
is a menu-driven tool that allows the user to draw and manipulate
objects interactively under the X Window System.  If
.I file
is given, it specifies the name of a file to be edited.
.PP
The bulk of the documentation for
.IR xfig
is in an HTML-based reference guide.
See the Help menu in
.IR xfig
or point your browser at
.IR /usr/share/doc/xfig/html/index.html .
There are both English and Japanese versions.
.PP
When using a two-button mouse instead of a three-button mouse, use the
.I <Meta>
key and the right button at the same time to effect
the action of the middle button.
.PP
.I Xfig
is available from
https://sourceforge.net/projects/mcj/.
.PP
The
.I Fig2dev
package is used when printing or exporting the output from
.IR xfig .
The
.IR fig2dev
program is automatically called by
.IR xfig
as a back-end processor to produce various types of output:
.PP
LaTeX, Metafont, PDF, PostScript or Encapsulated PostScript,
CGM and EMF (mostyl used under Windows),
tk (tcl/tk tool command language/tool kit package), SVG,
GIF, JPEG, PCX, PNG, PPM, TIFF,
XBM, XPM, Gerber, AutoCAD Slide, IBM-GL (HP/GL), Pic and
PiCTeX.
For use with TeX/LaTeX: box, epic, eepic, eepicemu,
pict2e, pstricks, tikz.
.PP
See man fig2dev for all options.
.PP
The
.I Fig2dev
package is available from
https://sourceforge.net/projects/mcj/.

Make xfig look at the timestamp on the .fig file and
automatically load it and display it every time it changes.
.\"-------
.At
.BR \-bal [ loon_delay ]
.I msec
.Ap

.Ap
Cause the font used for most buttons to be
.I font
(default = 6x13).
.\"-------
.At
.BR \-but_ [ per_row ]
.I number
.Ap
Specify the number of buttons wide the mode panel should be.
This is useful in conjunction with the
.B \-pheight
parameter to reduce the canvas height for small screens.
.\"-------
.At
.B \-cbg
.I color
.Ap
Use
.I color
as the background color for the canvas.
If you want to set the background of everything in xfig
(e.g. menus, etc.) use the general
.B -bg
option.
.\"-------
.At
.B \-center
.Ap
Set the print option to print the figure centered on the page.
This is the default.
.\"-------
.At
.BR \-centim [ ers ]

.I compose-key-file
.Ap
Use
.I compose-key-file
instead of
.I CompKeyDB
for compose (meta) key database.
If there are no
.RB `` / ''s
in the name, the file must reside in the
.I xfig
library directory,
.IR $XFIGLIBDIR ,
usually
.BR /usr/local/lib/X11/xfig .
If there are any
.RB `` / ''s
in the name it is taken as is (not relative to
.IR $XFIGLIBDIR ).
If there is a leading

.At
.BR \-me [ tric ]
.Ap
Make centimeters the unit of choice.
The option
.B -centimeters
may also be used.
Fig files saved in metric mode are, due to rounding issues, scaled down by about
5% when saved, and scaled up when read in. Using
.BR -inches " or " -imperial
avoids the scaling.
.IP \&
After
.I xfig
is started you may change the units from metric to
imperial or vice versa from a popup menu available by pressing mouse

.SH BUGS and RESTRICTIONS
Please send bug reports, fixes, new features etc. to:
.br
\&thomas.loimer@tuwien.ac.at
.PP
Because of the difference of the fonts shown on the canvas and the PostScript
fonts on printers, text alignment can be problematic.
.PP
Not all operations employ smart redrawing of objects which are altered
as a by product of the operation.
You may need to use
.I Redraw
in these cases.
.PP
If the image is panned or the
.I 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
.I Redraw
after the operation is complete.
.PP
When zoomed very large, the length of dashes in dashed lines will top out
at 255 pixels long.  This is due to a restriction in X
that the dash list is defined by char (255 pixels maximum for a dash).
The figure will print correctly, however.
.PP
When you do a copy/rotate with multiple copies,
only the creation of the last object can be undone with the Undo button.
.PP
Modifications to text using the popup search/update/replace/spell check panel
cannot be undone.

.B "Version 3.1:"
.sp 2
.in +4
.br
The only difference between protocol version 3.0 and version 3.1 is
that the position of the ``magnet'' has been shifted by 14 fig units.
In the 2.1 and older versions of xfig the grid was in 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 like 4 became 60 instead
of 74 ((4+1)*15 - 1).

.sp
.B "Version 3.2:"
.sp 2
.in +4
.br
The changes to the version 3.2 file protocol are the addition of the
paper size, print/export magnification, single/multiple page indicator
and a transparent color name used for GIF export to the header
of the file.
.br
The other difference in the version 3.2 protocol is the
mathematical model used for splines. The new version
uses X-splines which allows the user to mix interpolation and approximation
points in a same curve. More precisely, it means that an X-spline curve
is neither an interpolated spline nor an approximated one, it is BOTH
(the behaviour of each point is controlled by one single parameter
called ``shape factor''). For additional information about X-splines, see:
.sp
  "X-Splines: A Spline Model Designed for the End User"
  by C. Blanc and C. Schlick, Proceedings of SIGGRAPH'95
  http://dept-info.labri.u-bordeaux.fr/~schlick/DOC/sig1.html
.sp
Caveat: Because previous spline models (quadratic B-splines and Bezier
with hidden points) are no longer supported, curves that are present
in version 3.1 and older files are automatically converted to X-splines.
This translation is only an approximation process. It means that the
converted curves are not exactly the same as the original ones. Though
they are usually very close, some hand-fitting may be needed in
some pathological cases.
