you _cannot_ get a PostScript file when running pdflatex.
So you did something else, like viewing PostScript output.
Then LyX converts the jpegs to eps and maybe then anables

Hello Marc,

I came to the same conclusion about using the defaults.

I use the defaults with Windows and Lyx 1.3.7 and on Linux Fedora4
which has LyX1.3.6. On both systems I can use the DVI, all 3 pdf and
the postscript viewers, in order to view your file.

That means the image files are OK, and the doc syntax structure is OK,
once \graphics dvips is eliminated. On the Windows system the/my
Layout-Document-Packages, the graphics driver is set to default
(as yours was) and it works so it seems just \graphics dvips is
problematic and maybe your other documents have that line also.
You would still need to be careful if they contained eps images.

So I was going to recommend saving preferences somewhere safe,
just in case, but reinstalling the defaults because they work for other
people and there is a fair chance your editing of lyxrc was faulty.
And I learned a lesson about the value of providing minimal examples.

Hope your other files are easy to fix,
Stephen

The defaults do not seem to work under MacOSX, in that they specify xpdf
rather than open to view files. This is probably fine if the user
is using XWindows subsystem to run LyX, but not if the user wants
to run LyX under the MacOS GUI. The only changes I
made to the defaults were to lyxrc to change xpdf to open.
(yes, I could have just specified those two lines in lyxrc.
Instead I elected to just copy lyxrc.default and change those
2 lines. It should have resulted in the same thing.)

Everything else was as provided, as far as I can tell.
However, I will erase everything again and start over, using
just the defaults modulo the above changes, and see if it does,
in fact, work with the \graphics default entry in the test file.
Then will see if it works with my older files.

OK, I have completed a full reinstall (I'm getting VERY good at this!)

LyX 1.3.7 on MacOSX 10.4.4.
Downloaded from http://wiki.lyx.org/LyX/LyXOnMac?from=LyX.Mac

LaTeX install from MacTeX.dmg downloaded from Tug was not touched.

OK. I have deleted LyX, deleted all the preferences
Library-Application Support-LyX (actually deleted the whole directory)
I then reinstalled LyX from a fresh download.

Opened my a1.lyx that worked before...

LyX does a whole bunch of stuff on the console, creating the
Library/Application Support/LyX directory and doing some self
configuration.

When I try View - PDF (ps to pdf) it doesn't display the images.

Under Layout-Document-Packages, Postscript driver was set to dvips.
This was AFTER resetting it in the document previously, as documented
previous in this thread.

So I manually reset dvips back to default, apply...

View - PDF (ps to pdf) now works fine and display my images.

There is now no preferences file in the Library-Application Support- 
LyX

directory. However, LyX.app/Contents/Resources/lyx
in the dmg file I just downloaded has the following:

\format pdf pdf PDF (pdflatex) 
\format pdf2 pdf PDF (ps to pdf) 

This also appears in preferences where I've installed LyX.app.

So may I suggest that if this is so wrong that the distribution
itself needs to be fixed, since I can guarantee that I had
nothing to do with these settings.

regards,
Marc

Yes ... it appears to be my mistake somewhere along the line. But  
those two lines have been in the LyX/Mac default preferences for a  
while and haven't caused a problem before. Moreover, deleting those  
lines from within the LyX.app bundle -- i.e., the default LyX/Mac  
preferences -- does not affect bug 2127 substantially. (I'll post new  
comments on bugzilla so we have them there: http://bugzilla.lyx.org/ 
show_bug.cgi?id=2127.)

Yes. But it might have lead Marc to think that he is converting via 
pdflatex when he actually used ps2pdf. I think there are no more 
misunderstandings now :-)

Yes ... it appears to be my mistake somewhere along the line. But  
those two lines have been in the LyX/Mac default preferences for a

lines from within the LyX.app bundle -- i.e., the default LyX/Mac

So you did something else, like viewing PostScript output.
Then LyX converts the jpegs to eps and maybe then anables

Hello Marc,

I came to the same conclusion about using the defaults.

I use the defaults with Windows and Lyx 1.3.7 and on Linux Fedora4
which has LyX1.3.6. On both systems I can use the DVI, all 3 pdf and
the postscript viewers, in order to view your file.

That means the image files are OK, and the doc syntax structure is OK,
once \graphics dvips is eliminated. On the Windows system the/my
Layout->Document->Packages, the graphics driver is set to "default"
(as yours was) and it works so it seems just \graphics dvips is
problematic and maybe your other documents have that line also.
You would still need to be careful if they contained eps images.

So I was going to recommend saving preferences somewhere safe,
just in case, but reinstalling the defaults because they work for other
people and there is a fair chance your editing of lyxrc was faulty.
And I learned a lesson about the value of providing minimal examples.

Hope your other files are easy to fix,
Stephen

The defaults do not seem to work under MacOSX, in that they specify xpdf
rather than "open" to view files. This is probably fine if the user
is using XWindows subsystem to run LyX, but not if the user wants
to run LyX under the MacOS GUI. The only changes I
made to the defaults were to lyxrc to change xpdf to open.
(yes, I could have just specified those two lines in lyxrc.
Instead I elected to just copy lyxrc.default and change those
2 lines. It should have resulted in the same thing.)

Everything else was "as provided", as far as I can tell.
However, I will erase everything again and start over, using
just the defaults modulo the above changes, and see if it does,
in fact, work with the "\graphics default" entry in the test file.
Then will see if it works with my older files.

I did not talk about the viewer settings. Of course you can set them to 
"open", and it should work. I meant these two lines (found by Paul):

\format "pdf" "pdf" "PDF (pdflatex)" ""

OK, I have completed a full reinstall (I'm getting VERY good at this!)

LyX 1.3.7 on MacOSX 10.4.4.
Downloaded from http://wiki.lyx.org/LyX/LyXOnMac?from=LyX.Mac

LaTeX install from MacTeX.dmg downloaded from Tug was not touched.

OK. I have deleted LyX, deleted all the preferences
Library->Application Support->LyX (actually deleted the whole directory)
I then reinstalled LyX from a fresh download.

Opened my a1.lyx that worked before...

LyX does a whole bunch of stuff on the console, creating the
Library/Application Support/LyX directory and doing some self
configuration.

When I try View -> PDF (ps to pdf) it doesn't display the images.

Under Layout->Document->Packages, Postscript driver was set to dvips.
This was AFTER resetting it in the document previously, as documented
previous in this thread.

So I manually reset "dvips" back to default, apply...

View -> PDF (ps to pdf) now works fine and display my images.

There is now no preferences file in the Library->Application Support- 
>LyX

directory. However, LyX.app/Contents/Resources/lyx
in the dmg file I just downloaded has the following:

\format "pdf" "pdf" "PDF (pdflatex)" ""
\format "pdf2" "pdf" "PDF (ps to pdf)" ""

This also appears in preferences where I've installed LyX.app.

So may I suggest that if this is so wrong that the distribution
itself needs to be fixed, since I can guarantee that I had
nothing to do with these settings.

Marc

It seems my idea about converting the .eps file to .jpg format
was not the best way to proceed, but instead to use epstopdf.

http://mintaka.sdsu.edu/GF/bibliog/latex/LaTeXtoPDF.html

pdflatex method (details)

1. Convert all the figures to non-EPS form.

As  pdflatex  doesn't use EPS figures, we have to convert 
them all to either JPEG, PNG, or PDF form. It makes no sense 
to convert EPS to PNG, because that changes scalable graphics 
to bulky rasterised form. JPEG would be even worse, because 
of its lossy compression. 

The way to go is to convert EPS to PDF:  
epstopdf image.eps
which creates a file named  image.pdf  by default. (This has the 
happy side-effect of compressing the actual PostScript text of 
the original EPS file; if that file were longer than about 2 kB, the 
compression would more than offset the added PDF headers, 
and the PDF file could be smaller than its EPS parent.) 


2. Tell LaTeX what to expect.

The preamble to the LaTeX source file now looks much like 
the one used in the traditional method: 


\documentclass[pdftex,...]{article}  % the pdftex is essential
\usepackage[dvips]{graphicx} % to include images
\usepackage{pslatex}  % to use PostScript fonts

   % redefine float-placement parameters here 
\begin{document}


Note that the package name to put in the argument list 
is pdftex, not pdflatex. 


3. Include the figures in the *.tex file.

Just as in the traditional method, we can omit the filename suffix: 


\begin{figure}[htp]
\resizebox{\textwidth}{!}{
 \includegraphics[width=\textwidth]{circle1}
 }
\caption{circle1}
\end{figure}

But now, what's automatically found is the 
file circle1.pdf, not circle1.eps.

Stephen

Under LyX1.3.7, under View, there are three different .pdf viewing 
options, if your LyX is installed right. pdflatex is the recommended 
one, but it doesn't handle image files in the .eps format. Which is

why epstopdf is used to change the file format from .eps to .pdf.
pdflatex works with image files of the .png, .jpg and .pdf formats.

ps2pdf does work with .eps graphical files, but not the .jpg format 
So ps2pdf worked ok when you had one eps image within your

lyx document (and I presume within a (La)tex document). But then
you added another I think, .jpg image, which violated the boundaries 
of the ps2pdf conversion capability. 


On my system, I can view with a ghostscript viewer, gsview, or
Adobe Reader which reads .pdf files, save the file or print it out
on my printer. On Linux/Mac OS X the user .pdf viewer is xpdf
which I think you said you removed. 


Also under Lyx-File if you have a file open there is an active
choice to Export to .pdf or dvi or postscript. I know less about
that since the only time I use that is to export as Latex and that
exported file is made, but there isn't any indication of it, and I
think it is stored in a temp directory. 


Another place where the behavior of viewing files is controlled
is under LyX-Edit-Preferences, you will see File formats and
it displays the assigned Viewers for the different file formats.
Also you will see Converters which also lists three .pdf methods.


I've read the available documentation under Help, but can't

Usually the defaults work quite well and a user never has to fiddle
with the settings. Try loading your first file which I think had just
the .eps image; the one you said works with ps2pdf. This time
use the View windows and select ps2pdf and see if it still works.
Then try dvipdfm. I am not so sure you should have removed the
xpdf viewer, see how it works. If dvipdfm works with just the
one graphic image using View, then try it with the the file that has
two images (one eps and one jpg if I undertand you). You may
have to put xpdf back in as a viewer. You said you had pdflatex
working from the command line before, which would need your
jpg file and the image.pdf file (which you converted from image.eps)
using epstopdf (from the command line). Sometimes that epstopdf
conversion needs to have some bounding box (BB) work done on 
the image.eps file depending on how it was constructed. Edit your

homework .lyx file appropriately for BBs and adding images.

Herbert is the expert in this area. If I made any mistakes in 
explaining this I hope he corrects them. Perhaps part of the

problem so far is a lack of knowledge about LyX defaults.
http://wiki.lyx.org/ provides a searchable interface for some
topics. Google also contains a lot of information about (La)TeX
providing details about the pdf viewers which LyX relies upon,
but which come with the various (La)TeX versions and platforms.
Working instances of Ghostscript and Python are also needed.

I'll leave any further advice to more experienced users, Good luck,
Stephen

I have a LaTeX - PDF (ps to pdf) option that says:

Converter: pdflatex $$i
extra flag: latex


There's an inconsistency here.  I downloaded all the files from your 
directory.  The converters are defined in lyxrc, where the key lines (I 
think) are:


\Format pdf   pdf  PDF (ps2pdf) P
\Format pdf2  pdf  PDF (pdflatex)   F
\Format pdf3  pdf  PDF (dvipdfm)m
\converter latex pdf2 pdflatex $$i latex
\converter dvi pdf3 dvipdfm $$i 
\converter ps pdf ps2pdf13 $$i 

The first three lines declare three different extensions (pdf, pdf2, 
pdf3) to by used by LyX to indicate pdf files created three different 
ways (latex-dvi-ps-pdf, latex-pdf, latex-dvi-pdf respectively). 
The other three lines give the terminal conversion in each case.


In your preferences file, I found the following:

\format pdf pdf PDF (pdflatex) 
\format pdf2 pdf PDF (ps to pdf) 

Note that the labels for the pdf and pdf2 extensions are actually the 
reverse of what the converters do (i.e., pdf is via ps, not via 
pdflatex).  So if you're selecting View-PDF (ps to pdf), I think you're 
actually running pdflatex, and if you're selecting View-PDF (pdflatex), 
I think you're actually running latex, dvips and ps2pdf13.

I use jpeg because I was having trouble with other formats.
As in, LyX wouldn't even display them internally. Including png.
Since the clean install it seems to work ok, although no
better or no worse than jpg.

I'm not sure that creating something on the fly with gastex
is something I will be doing in the near future. Learning curve
seems a little high, and it doesn't seem condusive to taking
notes in class. Probably a lovely tool for writing a book or
paper. The better interface requirement is why I use LyX in
the first place! I don't want to have to type raw laTeX code.
I have in the past, and I didn't enjoy it.

I create my automata with Omnigraffle and export to jpg.
That tool also allows me to copy the professor's lectures from
the board on the fly. I'm not sure I could do that with gastex,
unless there is a better interface to it than a text editor.

replying to myself...

In testing, I've found that if I create a NEW file,
I get \graphics default.  This would explain why the new
file was working.

However, in a1.ps, even though I have set
the option to default, it seems to keep \graphics dvips
The file may have been created before my installation broke,
so I don't know if that was the way things were before.
Setting the options to dvips, saving, then setting them
back to default actually updated the file.

Now to try to solve the problem of it not working for any
other option, no matter what file format I use.  Prior to
my loss of /usr/local, it was working fine.  Now I open
my old files and I'm getting all sorts of errors and I can't
create pdfs from them at all, yet I could before.

I have been sent a couple more links for documentation, so
will read those before coming back with hopefully cogent
questions.

Herbert



It seems my idea about converting the .eps file to .jpg format
was not the best way to proceed, but instead to use epstopdf.

http://mintaka.sdsu.edu/GF/bibliog/latex/LaTeXtoPDF.html

pdflatex method (details)

1. Convert all the figures to non-EPS form.

As  pdflatex  doesn't use EPS figures, we have to convert 
them all to either JPEG, PNG, or PDF form. It makes no sense 
to convert EPS to PNG, because that changes scalable graphics 
to bulky rasterised form. JPEG would be even worse, because 
of its lossy compression. 

The way to go is to convert EPS to PDF:  
epstopdf image.eps
which creates a file named  image.pdf  by default. (This has the 
happy side-effect of compressing the actual PostScript text of 
the original EPS file; if that file were longer than about 2 kB, the 
compression would more than offset the added PDF headers, 
and the PDF file could be smaller than its EPS parent.) 


2. Tell LaTeX what to expect.

The preamble to the LaTeX source file now looks much like 
the one used in the traditional method: 


\documentclass[pdftex,...]{article}  % the pdftex is essential
\usepackage[dvips]{graphicx} % to include images
\usepackage{pslatex}  % to use PostScript fonts

   % redefine float-placement parameters here 
\begin{document}


Note that the package name to put in the argument list 
is pdftex, not pdflatex. 


3. Include the figures in the *.tex file.

Just as in the traditional method, we can omit the filename suffix: 


\begin{figure}[htp]
\resizebox{\textwidth}{!}{
 \includegraphics[width=\textwidth]{circle1}
 }
\caption{circle1}
\end{figure}

But now, what's automatically found is the 
file circle1.pdf, not circle1.eps.

Stephen

Under LyX1.3.7, under View, there are three different .pdf viewing 
options, if your LyX is installed right. pdflatex is the recommended 
one, but it doesn't handle image files in the .eps format. Which is

why epstopdf is used to change the file format from .eps to .pdf.
pdflatex works with image files of the .png, .jpg and .pdf formats.

ps2pdf does work with .eps graphical files, but not the .jpg format 
So ps2pdf worked ok when you had one eps image within your

lyx document (and I presume within a (La)tex document). But then
you added another I think, .jpg image, which violated the boundaries 
of the ps2pdf conversion capability. 


On my system, I can view with a ghostscript viewer, gsview, or
Adobe Reader which reads .pdf files, save the file or print it out
on my printer. On Linux/Mac OS X the user .pdf viewer is xpdf
which I think you said you removed. 


Also under Lyx-File if you have a file open there is an active
choice to Export to .pdf or dvi or postscript. I know less about
that since the only time I use that is to export as Latex and that
exported file is made, but there isn't any indication of it, and I
think it is stored in a temp directory. 


Another place where the behavior of viewing files is controlled
is under LyX-Edit-Preferences, you will see File formats and
it displays the assigned Viewers for the different file formats.
Also you will see Converters which also lists three .pdf methods.


I've read the available documentation under Help, but can't
recall any detailed documentation on exactly what LyX calls
to convert the LyX code to LaTeX and then to PDF. Once I understand
that process, I'll be able to see what might be broken on

Usually the defaults work quite well and a user never has to fiddle
with the settings. Try loading your first file which I think had just
the .eps image; the one you said works with ps2pdf. This time
use the View windows and select ps2pdf and see if it still works.
Then try dvipdfm. I am not so sure you should have removed the
xpdf viewer, see how it works. If dvipdfm works with just the
one graphic image using View, then try it with the the file that has
two images (one eps and one jpg if I undertand you). You may
have to put xpdf back in as a viewer. You said you had pdflatex
working from the command line before, which would need your
jpg file and the image.pdf file (which you converted from image.eps)
using epstopdf (from the command line). Sometimes that epstopdf
conversion needs to have some bounding box (BB) work done on 
the image.eps file depending on how it was constructed. Edit your

homework .lyx file appropriately for BBs and adding images.

Herbert is the expert in this area. If I made any mistakes in 
explaining this I hope he corrects them. Perhaps part of the

problem so far is a lack of knowledge about LyX defaults.
http://wiki.lyx.org/ provides a searchable interface for some
topics. Google also contains a lot of information about (La)TeX
providing details about the pdf viewers which LyX relies upon,
but which come with the various (La)TeX versions and platforms.
Working instances of Ghostscript and Python are also needed.

I'll leave any further advice to more experienced users, Good luck,
Stephen

I have a LaTeX - PDF (ps to pdf) option that says:

Converter: pdflatex $$i
extra flag: latex


There's an inconsistency here.  I downloaded all the files from your 
directory.  The converters are defined in lyxrc, where the key lines (I 
think) are:


\Format pdf   pdf  PDF (ps2pdf) P
\Format pdf2  pdf  PDF (pdflatex)   F
\Format pdf3  pdf  PDF (dvipdfm)m
\converter latex pdf2 pdflatex $$i latex
\converter dvi pdf3 dvipdfm $$i 
\converter ps pdf ps2pdf13 $$i 

The first three lines declare three different extensions (pdf, pdf2, 
pdf3) to by used by LyX to indicate pdf files created three different 
ways (latex-dvi-ps-pdf, latex-pdf, latex-dvi-pdf respectively). 
The other three lines give the terminal conversion in each case.


In your preferences file, I found the following:

\format pdf pdf PDF (pdflatex) 
\format pdf2 pdf PDF (ps to pdf) 

Note that the labels for the pdf and pdf2 extensions are actually the 
reverse of what the converters do (i.e., pdf is via ps, not via 
pdflatex).  So if you're selecting View-PDF (ps to pdf), I think you're 
actually running pdflatex, and if you're selecting View-PDF (pdflatex), 
I think you're actually running latex, dvips and ps2pdf13.


 
Now that the homework has been handed in (manual cut

and paste of images) I've posted the .lyx file to
http://ryuu.ca/lyx, along with the images, in case anyone
wants to see the raw source. I've also posted my preferences
and lyxrc files in the same directory. All will vanish
once this is solved, but it might help, and it can't hurt.



I ran your document with LyX 1.3.7, Win XP, MiKTeX.  No matter how I 
view it, it comes out correct.  I also exported to latex and ran latex 
(twice, dvips, and ps2pdf13 in that order, and got a correct PDF file. 
I notice from your path that you're using teTeX.  Maybe a component 
needs upgrading?

And by the way, it is a kind of crazy to convert your
automata images to jpeg. png or odf is the right format,
or what I would prefer, create them on the fly with gastex.


I use jpeg because I was having trouble with other formats.
As in, LyX wouldn't even display them internally. Including png.
Since the clean install it seems to work ok, although no
better or no worse than jpg.

I'm not sure that creating something on the fly with gastex
is something I will be doing in the near future. Learning curve
seems a little high, and it doesn't seem condusive to taking
notes in class. Probably a lovely tool for writing a book or
paper. The better interface requirement is why I use LyX in
the first place! I don't want to have to type raw laTeX code.
I have in the past, and I didn't enjoy it.

I create my automata with Omnigraffle and export to jpg.
That tool also allows me to copy the professor's lectures from
the board on the fly. I'm not sure I could do that with gastex,
unless there is a better interface to it than a text editor.

replying to myself...

In testing, I've found that if I create a NEW file,
I get \graphics default.  This would explain why the new
file was working.

However, in a1.ps, even though I have set
the option to default, it seems to keep \graphics dvips
The file may have been created before my installation broke,
so I don't know if that was the way things were before.
Setting the options to dvips, saving, then setting them
back to default actually updated the file.

Now to try to solve the problem of it not working for any
other option, no matter what file format I use.  Prior to
my loss of /usr/local, it was working fine.  Now I open
my old files and I'm getting all sorts of errors and I can't
create pdfs from them at all, yet I could before.

I have been sent a couple more links for documentation, so
will read those before coming back with hopefully cogent
questions.

Marc

It seems my idea about converting the .eps file to .jpg format
was not the best way to proceed, but instead to use epstopdf.

http://mintaka.sdsu.edu/GF/bibliog/latex/LaTeXtoPDF.html

pdflatex method (details)

1. Convert all the figures to non-EPS form.

As  pdflatex  doesn't use EPS figures, we have to convert 
them all to either JPEG, PNG, or PDF form. It makes no sense 
to convert EPS to PNG, because that changes scalable graphics 
to bulky rasterised form. JPEG would be even worse, because 
of its lossy compression. 

The way to go is to convert EPS to PDF:  
epstopdf image.eps
which creates a file named  image.pdf  by default. (This has the 
happy side-effect of compressing the actual PostScript text of 
the original EPS file; if that file were longer than about 2 kB, the 
compression would more than offset the added PDF headers, 
and the PDF file could be smaller than its EPS parent.) 


2. Tell LaTeX what to expect.

The preamble to the LaTeX source file now looks much like 
the one used in the traditional method: 


\documentclass[pdftex,...]{article}  % the pdftex is essential
\usepackage[dvips]{graphicx} % to include images
\usepackage{pslatex}  % to use PostScript fonts

   % redefine float-placement parameters here 
\begin{document}


Note that the package name to put in the argument list 
is pdftex, not pdflatex. 


3. Include the figures in the *.tex file.

Just as in the traditional method, we can omit the filename suffix: 


\begin{figure}[htp]
\resizebox{\textwidth}{!}{
 \includegraphics[width=\textwidth]{circle1}
 }
\caption{circle1}
\end{figure}

But now, what's automatically found is the 
file circle1.pdf, not circle1.eps."

Stephen

Yes, my sentence was correcting an earlier post which suggested

I should have put a comma after "proceed, but instead,..."

Under LyX1.3.7, under View, there are three different .pdf viewing 
options, if your LyX is installed right. pdflatex is the recommended 
one, but it doesn't handle image files in the .eps format. Which is

why epstopdf is used to change the file format from .eps to .pdf.
pdflatex works with image files of the .png, .jpg and .pdf formats.

ps2pdf does work with .eps graphical files, but not the .jpg format 
So ps2pdf worked ok when you had one eps image within your

lyx document (and I presume within a (La)tex document). But then
you added another I think, .jpg image, which violated the boundaries 
of the ps2pdf conversion capability. 


On my system, I can view with a ghostscript viewer, gsview, or
Adobe Reader which reads .pdf files, save the file or print it out
on my printer. On Linux/Mac OS X the user .pdf viewer is xpdf
which I think you said you removed. 


Also under Lyx->File if you have a file open there is an active
choice to Export to .pdf or dvi or postscript. I know less about
that since the only time I use that is to export as Latex and that
exported file is made, but there isn't any indication of it, and I
think it is stored in a temp directory. 


Another place where the behavior of viewing files is controlled
is under LyX->Edit->Preferences, you will see File formats and
it displays the assigned Viewers for the different file formats.
Also you will see Converters which also lists three .pdf methods.


I've read the available documentation under "Help", but can't
recall any detailed documentation on exactly what LyX calls
to convert the LyX code to LaTeX and then to PDF. Once I understand
that process, I'll be able to see what might be broken on
my system, maybe even contribute a general-purpose script

Usually the defaults work quite well and a user never has to fiddle
with the settings. Try loading your first file which I think had just
the .eps image; the one you said works with ps2pdf. This time
use the View windows and select ps2pdf and see if it still works.
Then try dvipdfm. I am not so sure you should have removed the
xpdf viewer, see how it works. If dvipdfm works with just the
one graphic image using View, then try it with the the file that has
two images (one eps and one jpg if I undertand you). You may
have to put xpdf back in as a viewer. You said you had pdflatex
working from the command line before, which would need your
jpg file and the image.pdf file (which you converted from image.eps)
using epstopdf (from the command line). Sometimes that epstopdf
conversion needs to have some bounding box (BB) work done on 
the image.eps file depending on how it was constructed. Edit your

homework .lyx file appropriately for BBs and adding images.

Herbert is the expert in this area. If I made any mistakes in 
explaining this I hope he corrects them. Perhaps part of the

problem so far is a lack of knowledge about LyX defaults.
http://wiki.lyx.org/ provides a searchable interface for some
topics. Google also contains a lot of information about (La)TeX
providing details about the pdf viewers which LyX relies upon,
but which come with the various (La)TeX versions and platforms.
Working instances of Ghostscript and Python are also needed.

I'll leave any further advice to more experienced users, Good luck,
Stephen

Delete the line

Thank you.

I still don't understand where that line came from, since

And by the way, it is a kind of crazy to convert your
automata images to jpeg. png or odf is the right format,
or what I would prefer, create them on the fly with gastex.


I use jpeg because I was having trouble with other formats.
As in, LyX wouldn't even display them internally. Including png.
Since the clean install it seems to work ok, although no
better or no worse than jpg.

I'm not sure that creating something "on the fly" with gastex
is something I will be doing in the near future. Learning curve
seems a little high, and it doesn't seem condusive to taking
notes in class. Probably a lovely tool for writing a book or
paper. The "better interface" requirement is why I use LyX in
the first place! I don't want to have to type raw laTeX code.
I have in the past, and I didn't enjoy it.

I create my automata with Omnigraffle and export to jpg.
That tool also allows me to copy the professor's lectures from
the board on the fly. I'm not sure I could do that with gastex,
unless there is a better interface to it than a text editor.

Marc

replying to myself...

In testing, I've found that if I create a NEW file,
I get \graphics default.  This would explain why the new
file was working.

However, in a1.ps, even though I have set
the option to "default", it seems to keep \graphics dvips
The file may have been created before my installation broke,
so I don't know if that was the way things were before.
Setting the options to dvips, saving, then setting them
back to default actually updated the file.

Now to try to solve the problem of it not working for any
other option, no matter what file format I use.  Prior to
my loss of /usr/local, it was working fine.  Now I open
my old files and I'm getting all sorts of errors and I can't
create pdfs from them at all, yet I could before.

I have been sent a couple more links for documentation, so
will read those before coming back with hopefully cogent
questions.

Marc

From the Latex Companion: You did not specify an explicit image size on 
the \includegraphics command and LaTeX was unable to determine the 
image size. It usually does this automatically for EPS files by reading 
bounding box info. However... it may be unable to extract this 
information from binary bitmap images such as .jpeg files.

In my experience (1.3.5) LyX converts jpegs to an EPS automagically. And 
above it does say type eps...

You could, as a workaround, try doing this yourself (save the jpeg as an 
eps). I would also first try one of the LyX help docs (with images) to 
see if have the same problem.

This should not happen: pdflatex can use .jpg files natively. Did you check
whether the file in the temp dir does actually exist and is readable? Can
you run a simple .tex file that includes this very image through pdflatex?

What does specified as eps mean? If it means that this file is actually n

pdflatex can't handle .eps images.

If the .eps image file is causing a problem, could you convert it
.jpg and reference the .jpg version rather than the .eps in LyX?
Maybe the eps conversion is faulty and if it is the file itself then
it might fail to convert to another image format, so narrow it down.

I did a search for TeXshop and error messages. 
Maybe this will be helpful, maybe not. Most of the users use 
systems other than Macs and/or Texshop so don't have answers
arising from their own experience.

This was reported by Andreas in the beginning of July(05). He also 
observed that the bug could be fixed by inserting some quotes

around referenced variables.  (This revealed some very strange
phenomena that have not yet been explained...)  


Lars and Jon pointed out that the real problem is a missing

http://www.uoregon.edu/~koch/texshop/version.html [SH: unlikely]

The default TeXShop preference for the teTeX binary directory is 
/usr/local/teTeX/bin/powerpc-apple-darwin-current. But if users 
have installed Gerben Wierda's latest TeX redistribution, they 
also have Intel binaries. On Intel machines, the teTeX binary 
directory should then be 
/usr/local/teTeX/bin/i386-apple-darwin-current. TeXShop now has 
code to make this change automatically. When the program first 
starts, it calls uname -p to determine the current processor. 
If the result is i386, then TeXShop permanently changes the 
above preference to /usr/local/teTeX/bin/i386-apple-darwin-current. 
However this change is not made if the user has manually changed 
the default /usr/local/teTeX/bin/powerpc-apple-darwin-current to 
some other location. Thus if a user has the Fink teTeX distribution 
or some other distribution and has set the teTeX binary directory 
preference to point to it, the preference will not be changed.

That seems plausible since the error message he reported is
caused by an improper bounding box, or an incorrect filename.

Margins, cropping, and bounding boxes 

Every PostScript file included in a LATEX document must have 
a defined bounding box. Normally, the bounding box is defined 
using a structured comment at the beginning of the PostScript 
file. For example, the PostScript source for the figures shown 
above begins like this: 


%!PS-Adobe-3.0
%%BoundingBox: 90 252 540 684

In some cases, you may need to redefine the bounding box, 
either to adjust the amount of white space surrounding the 
figure or to crop your figure by selecting a clipping region. 
You may do so either by editing the PostScript file or in 
the LATEX source file. Any bounding box definitions in the 
LATEX source override those in the PostScript file. For 
details, see section 11.3, Merging Text and PostScript 
Graphics, in The LATEX Companion, pp. 317-320. 

An easy way to determine the correct bounding box is to 
view your figure using ghostview. Move the mouse pointer to 
the lower left corner of the figure and note the coordinates 
(displayed by ghostview immediately above the File button); 
these are the first two numbers in the BoundingBox line. 
Now move the mouse pointer to the upper right corner of the 
figure; the coordinates displayed are the last two numbers 
in the BoundingBox line. 

(This plot does not float within the text, since it was 
not put into a figure environment; rather, it appears in the 
same place in the output as in the LATEX source file.) Note 
that the = is required in the clip= option, although no 
value follows the =. Also note that the clip= option is 
ignored by pdfLATEX (see this figure in the PDF version of 
this book).

Stephen

What does specified as eps mean? If it means that this file is

I wish it was that easy.  That just happened once (so, of course,
that was the one I copied. Sigh).  It does exactly the same thing

I have reinstalled my LaTeX environment from the latest MacTeX image,
I've checked to make sure that all the paths are working, and that
everything is correctly installed.

I now get the following errors in the LaTeX log:

Why would it say type eps when it's a jpeg file? Why would it
have hbox overfull on the pathname to the file (that's line 468 in the
tex file. I tried shortening the path - same error)
I have no idea, and I'm giving up for now.

I'd like to thank all those who tried to help.

I know this can work: I had it working all last year with NO problems.
Large images, multiple include files, everything worked. Now... I can't
even print a frigging 3 page assignment with 1 small image.

It's only since installing new versions of teTeX and LyX that I have
experienced these problems.  I'm going to try to find my notes from last
year on how to install teTeX and LyX and try going back to previous
versions to see if I can get things to work again. Later. After class
and after I get some sleep.

Again, thanks to those who have tried to help.

Marc

I'm at my wits end. Can someone please tell me at least WHAT is wrong,
in terms of why LyX isn't able to create LaTeX code that works in
this case?
What is LyX is doing (or not doing) that creates this LaTeX error?
What should either LyX or myself should be doing to correct the problem?
I have googled, read the archives, searched, scoured, and generally
beat my head on this for many hours now, and I'm no closer to a clue.

Please, can someone help?

Do I have the wrong version of teTeX? Did I load the wrong tools?
This type of thing used to work without any problems with 1.3.4, 1.3,5
and 1.3.6 prior to a system error I had last week. Now, it's not working
at all.

What are the people using MacOSX generally using as the teTeX install?
I followed the instructions for Texshop, and used the 2006 MacTex.dmg
to install the necessary teTeX files. Should I be using something else?
I vaguely recall doing something different the first time I installed
teTeX, but do you think I can find my old notes? Not a chance!

All I'm doing is inserting a graphic into a file. That is the only
change between the two files.

Here are the differences between a file that works and one
that doesn't:

From the Latex Companion: You did not specify an explicit image size on 
the \includegraphics command and LaTeX was unable to determine the 
image size. It usually does this automatically for EPS files by reading 
bounding box info. However... it may be unable to extract this 
information from binary bitmap images such as .jpeg files.

In my experience (1.3.5) LyX converts jpegs to an EPS automagically. And 
above it does say type eps...

You could, as a workaround, try doing this yourself (save the jpeg as an 
eps). I would also first try one of the LyX help docs (with images) to 
see if have the same problem.

We don't know, but with your help we might find out. Maybe this is bug 2127
(but I doubt it, see below): http://bugzilla.lyx.org/show_bug.cgi?id=2127.

 What should either LyX or myself should be doing to correct the problem?

First we need to find out whether the error is on the LyX side or TeX side.
Export the file to LaTeX, and run it through pdflatex manually. Does that
work? If not, what are the error messages?

This is different to bug 2127: There LyX tries to run TeX in dvi mode, here
it does the right thing.

This should not happen: pdflatex can use .jpg files natively. Did you check
whether the file in the temp dir does actually exist and is readable? Can
you run a simple .tex file that includes this very image through pdflatex?

If the .eps image file is causing a problem, could you convert it
.jpg and reference the .jpg version rather than the .eps in LyX?
Maybe the eps conversion is faulty and if it is the file itself then
it might fail to convert to another image format, so narrow it down.

I did a search for TeXshop and error messages. 
Maybe this will be helpful, maybe not. Most of the users use 
systems other than Macs and/or Texshop so don't have answers
arising from their own experience.

This was reported by Andreas in the beginning of July(05). He also

around referenced variables.  (This revealed some very strange

Lars and Jon pointed out that the real problem is a missing

http://www.uoregon.edu/~koch/texshop/version.html [SH: unlikely]

The default TeXShop preference for the teTeX binary directory is 
/usr/local/teTeX/bin/powerpc-apple-darwin-current. But if users 
have installed Gerben Wierda's latest TeX redistribution, they 
also have Intel binaries. On Intel machines, the teTeX binary 
directory should then be 
/usr/local/teTeX/bin/i386-apple-darwin-current. TeXShop now has 
code to make this change automatically. When the program first 
starts, it calls uname -p to determine the current processor. 
If the result is i386, then TeXShop permanently changes the 
above preference to /usr/local/teTeX/bin/i386-apple-darwin-current. 
However this change is not made if the user has manually changed 
the default /usr/local/teTeX/bin/powerpc-apple-darwin-current to 
some other location. Thus if a user has the Fink teTeX distribution 
or some other distribution and has set the teTeX binary directory 
preference to point to it, the preference will not be changed.
