It is a LyX issue. xfig (or any other program) does not know (and should not 
need to know) about the internals of file inclusion of LyX.

Thanks, Georg,

now I got it. 
I am translating Georg's hint for entering .fig files with greek letters in 
Lyx, since other people might have a problem with it too.

You imported the xfig-file as a grafic. But in this case the special mechanism 
for exchanging the text does not work. Instead, a direct .eps/.pdf is 
produced with the same text as in xfig (e.g. $\alpha$)

If you enter the grafic via insert>file>external material 
and chose in the dialog type xfig, $\alpha$ is given as desired by α.

You are not the first one who was fooled by it by not noticing the small 
difference between these two methods of including grafics. 
Therefore exists since more than 10 years the plan to bring together both, 
but nobody has so far implemented it.

Thanks again, Georg.

Could you tell me, whether this 'bring together both' is a task for xfig or 
for grafics/external material on the lyx side?

You need to do this before entering the text. Then it works for me. I don't 
know how to change these settings for existing text. It looks like they are 
some global settings that only influence newly created text.

You should not define anything related to xfig yourself here. If this 
converter is defined in your preferences file, please delete it from there. 
If it is in the syntax.default file (which is created by reconfigure) then 
it is fine.

Yes, I agree with you that LyX can already preview the xfig

But, can it preview the math text like $x_2$ in its final

I checked out fig2ps and it is a neat program.

I have been playing around with the converters in LyX,

It seems like you could define a converter to use

It is possible to force specialtext from hte fig2ps command line.

If they miss the flag, then you simply need to set the flag in the .fig file
(manually or with a script).

No. I mean what Abdel uses: Insert->File->External Material and then choose
the xfig template. In the file dialog you specify the .fig file. If you
want to edit the .fig file from within LyX press cklick on the file and
then press the edit button in the dialog that opens.

No, the -specialtext switch is only the default for new textboxes. Therefore
it is useful, but it does not change existing ones. How the text is output
to LaTeX depends on the flags that are stored in the .fig file, not on
the -specialtext switch.

If they miss the flag, then you simply need to set the flag in the .fig file
(manually or with a script). No ned to look at pstex_t. Then you include
all .fig files as external material, and maybe set the preamble command
mentioned by Vasek.

No, a textbox is what you get when you press the big T in xfig and where you
enter your text.

It does not find it out. It puts the text in a file that is processed by
LaTeX.

To do that, you really need the "special" flag switched on for strings in 
xfig. If you did not do it in your xfig files, you can change it quite 
efficiently using "update" functionality in xfig gui, or by a script on raw 
xfig file format. All strings are terminated by \001 so it is easy to detect 
them and the special flag is just one of the numbers in front of the text. Do 
not remember which one, you can easily find it out by diffing two files, one 
with and one without the special flag.

As a second step, redefine latex macro SetFigFont in the preamble:
either
\gdef\SetFigFont#1#2#3#4#5{\relax}
or 
\gdef\SetFigFontNFSS#1#2#3#4#5{\relax}
depending on the xfig version. Check one of your .pdftex_t file which version 
is used in it.

Then, all texts will be typeset by the active font in latex.

Hope this helps,
Vasek

Does it mean, I have to create the fig file after having started 
xfig -specialtext and xfig then puts my text in the pstex_t file with 
location marks etc?
With other words, I have to redo all my fig files and add (or copy, if I find 
out how the localization of the text is done in pstex_t)?

How does xfig find out the size and font I used in the document, or does it 
make latex take it over?

The external template way is supposed to be easier, since it does the
exporting automatically, so you can't get outdated figures because you
forgot to export.

The special flag is a property of each text box that you have to set
individually. AFAIK the -specialtext switch only sets that as default for
new text. If you have a lot of files that you need to convert it would
probably easy to write a small script that does this.

You should not need to worry about pstex_t and friends if you use the
external template. LyX is supposed to create all needed files
automatically, whether you use pdflatex or the traditional DVI. The only
decision you have to make is whether you want to use the special flag or
not: If you use it, the text will be typeset by LaTeX, and you can use
math, own commands that are defined in ERT or the preamble etc. The size
and font would also be adjusted through LaTeX commands. If you do not use
the special flag the text will appear as is in the final document, and you
set the font, size etc. in xfig.

You do not need to set anything in the preamble unless you use the xfig
special text flag and inserted nonstandard commands in a textbox of the
xfig file yourself.

If the special flag was set you encountered a bug, either in xfig, fig2dev
or in LyX. Otherwise just set the flag, and the text should be typeset by
LaTeX.

Wolfgang,

  No. I size the text in the figure to the figure (keeping in mind that it
will probably be smaller in the document), and pay no attention to the font
size relative to the text. The image is its own entity and the text should
be scaled to the graphics ... and clarity.


Thats what I did so far. But what about the pstex and the pstex_t which
you get after running xfig -specialtext? I thought this is the way to
divide the image part of the fig and the text part so that the latter can
be adjusted (by the program) to the font size of my text (and also to
include e.g. greek letters as latex etc).


  I've not done this. I create the figures separately, then insert them in
floats. If they're not readable in the pdf, I adjust the text size and try
again. For my purposes, 10pt or 12pt text in the figure is perfectly
readable.

  When I start a new figure, I change the default font (lower right corner
of the bottom) to 'postscript fonts' and select Palatino-Roman. Depending on
how much text will be in the figure, I leave the default size at 12pt (light
text) or reduce it to 10pt (a lot of text). Then I create the figure and
export it as .eps and put it in the document.

HTH,

Rich

Rich, thanks: 
What about the size of the text in your fig -> eps file in respect to the size 
of the text of the body (that is the document text, I guess?). Do you adjust 
it just by comparing it? Thats what I did so far. But what about the pstex 
and the pstex_t which you get after running xfig -specialtext? I thought this 
is the way to divide the image part of the fig and the text part so that the 
latter can be adjusted (by the program) to the font size of my text (and also 
to include e.g. greek letters as latex etc). If I check my  pstex file, it 
still shows the image and the text, as it was in the normal .fig file. The 
pstex_t file reads like:
\begin{picture}(0,0)%
\includegraphics{S021n.pstex}%
\end{picture}%
\setlength{\unitlength}{3947sp}%
%
\begingroup\makeatletter\ifx\SetFigFontNFSS\undefined%
\gdef\SetFigFontNFSS#1#2#3#4#5{%
  [EMAIL PROTECTED]
  \fontfamily{#3}\fontseries{#4}\fontshape{#5}%
  \selectfont}%
\fi\endgroup%
\begin{picture}(7881,10984)(1694,-10257)
\end{picture}%

perhaps I have to define things (see undefined% in the fifth line)

 I just did not get it yet, some step might be missing (perhaps something in 
the preamble

Use the external inset ("Inset->File->External Material") and choose the 
XFig template. You should also select "preview" in the display combo AFAIR.



I am using version 1.5.4 of LyX
Has 1.5.5 or 1.6 a feature to insert fig files directly and the rest is done 
by the program?


1.5.5 is the same as 1.5.4 in this regard. 1.6 will save you on choosing 
"preview" on the display combo, that's all.

Wolfgang,

  I can try.


I have quite a number of xfig produced files which are all exported as .eps
files and inserted in the LyX document as floats.


  That's what I've done, too.


My aim is to have the text of my fig files in the same font and size as the
text in the document. This is not the case now.



Do I have to use for all my fig files the xfig -specialtext or is there a
global command to do that for all files in one run?


  I do not know if you can post-process the typeface, but I made the
Palatino typeface the standard in Xfig images because that's the standard
typeface I use in all my documents. This produces the same text appearance
in both body and images.


And how exactly do I get it into the document? Is it the pstex or the
pstex_t file or both? Or is this done internally by LyX? With Enter
(Einfuegen) File (Datei) external Material I get the fig file but the text
of the pdf output is not scaled correctly (nor the fonts). Somehow I
haven't caught the way of entering it.


  I've always used Insert -> Float -> Float Figure, then specified the file
in the dialog box.

  Perhaps I don't understand your concerns well enough.

OK, so the ReplaceEnvironmentPath thingie should be moved as last in
the function. However, it strikes me that the command is called through
system() and thus the environment variables will be interpreted
correctly there (yes, I did check the fact). Therefore I propose the
following patch.

Where's the file? (.lyx and .fig)

Incidentally, can you not use the Include inset for this? 
That way you can get a preview of the figure with 1.3.0cvs.

Yes, that was it!! Thanks a lot.. the problem with the crash in 1.3.0cvs
(when including a .fig directly using external material) still remains..
so Wayan, I'm attaching a .fig file here and this is the error that
1.3.0cvs gives when it crashes:

No, I don't think so. But if you use fig2dev -L it produces the definition
of SetFigFont:

That probably because of the LaTeX tag inserted in fig or LaTeX tag
created by Xfig were wrong. For example, if I made a graphic with gnuplot
a degree symbol in german keyboard (if it was defined as a set encoding
bla-bla-bla) was wrong defined by Xfig (for pstex_t).

Could you send the fig or pstex* files?
Perhaps, I can try next 3 hrs... I have use 1.3.0cvs without any problem
for both pstex_t and fig format.

Ok.. I did that but still the problem of the undefined control sequence
remains.. on further investigation, I think the problem is with fonts
that XFig exports.. the error I get is:

(qingeg.pstex_t 
! Undefined control sequence.
 ... }{\mddefault }{\updefault }{\color 
  [rgb]{0,0,0}$M_1$}
l.14 }}}


The line in the .pstex_t file is:

\put(10351,-5236){\makebox(0,0)[lb]{\smash{\SetFigFont{12}{14.4}{\rmdef
ault}{\mddefault}{\updefault}{\color[rgb]{0,0,0}$M_1$}%
}}}

For some reason I think it doesn't like SetFigFont or so.. is this part
of standard Latex?
