images appear bigger

[Murpholino x]

I am doing my thesis with LYX

After a few ctrl-shift-R... images appear bigger in the pdf
I say ok, no problem... I have my backup at another partition.

I changed to the other partition and opened my thesis (a few days older)
with LYX and everything was ok
but after a couple of minutes, and after a few ctrl-shift-R got the same
problem.

I export my thesis to eps, and images are the size they used to be. But it
takes longer.

The problem is evince?
How can I solve that?

I am using Lubuntu 11.10

Do you need something else? please let me know

There are (at least) 3 ways:

For all methods, you must mark the text in question as Greek.

a) use the pre-composed Unicode characters in the Greek extended block
   (drag and drop from somewhere or use InsertSymbols).

b) use the LGR transliteration which is described in the babel Greek
   documentation http://mirror.ctan.org/info/babel/babel.pdf
   
   There is no need to use ERT (except, maybe for the tilde character).
  
   If you start with method a), you can also use the ViewSource feature to
   see the translation to the LGR transliteration (unless the document
   output encoding is set to Unicode (utf8)).
   
   Alternatively, you can look in the file unicodesymbols in the LyXdir to
   see how LyX maps the Unicode characters to LaTeX code.
   
c) if you load the LGRX extended font definitions for the Greek LGR fonts
   (http://milde.users.sourceforge.net/LGR/) in the latex preamble, you
   can also use standard accent commands (and their extensions) as
   described in http://milde.users.sourceforge.net/LGR/lgrxenc.pdf For
   single accents, this should also work with accent-... LyXfuns + base
   character in the minibuffer or bound to some key.


For quotes that you can drag and drop from somewhere, I recommend a). For
larger input by hand without a Greek-Unicode keybord mapping b) might
be more convenient. All methods can also be combined (with some
experimentation).

 A Lyx newbee myself I am a long way to have it replacing TeXworks but
 under the latter and pdfLaTeX I use the command \usepackage{psibycus} %

LyX uses Greek fonts in the LGR font encoding instead of the ibycus
encoding, therefore the input conventions differ.

aspect ratio in figures

[Allen Barker]

I'm having some problems with the aspect ratio of figures
which are inserted into Lyx.  This is with version 2.0.3
on a Fedora 15 system.

I insert a .png screenshot with insert-graphics and set
the width to some value (with the maintain aspect ratio box
checked).  The preview looks fine.  But, when the file is
printed in PDF the aspect ratio is not preserved.  For
example, a square image is stretched too much vertically
(by a very noticeable amount).  Postscript is the same.

If I set both the width and the height then the PDF
comes out as it should.  If I view as LyxHTML then the
size is also correct.

I'm just using the default article style, with no packages
inserted and an empty preamble.

Any ideas what's going on?

This is exactly what I was trying to do, but I cannot get it to work. Example:

If I enter

epim'eleia eato\~u

and set the language to Greek Poutoniko, this is what I get in the pdf:

 επιμέλεια εατο\ῦ

which is unsurprising, since the latex code in Viewsource is:

\foreignlanguage{polutonikogreek}{\textless{}epim'eleia
\textgreater{}eato\textbackslash{}\textasciitilde{}u}

(You mentioned probelms with the tilde, but not even the breathing
accents are correct. and the Latex looks completely wrong)

If, instead, I enter  \textgreek{epim'eleia eato\~u} in ERT, I get
the expected output

Can't open files in 2.0.3 (Buffer_convertLyxFormat.hXXXX is not a readable Lyx Document)

[John Enright]

Since upgrading to 2.0.3, Many of my files will not open. I get an error message
during the open operation saying:

C:\Users\myusername\AppData\Local\Temp\lyx_tmpdir.p10476
\Buffer_convertLyxFormat.h is not a readable LyX document.

The temp directory exits (as specified in the message); the temp file is
zero-bytes long.

- I'm running Win7 (x64). My MikTex is up to date. I've reinstalled LyX several
times (including uninstalling it). No difference. 

- Some old files will open. But many will not. Not sure of what is special about
the affected files. Perhaps some particular floats, but I can't seem to
replicate the problem with a new file.

- I can create and reopen a completely new file. 

- The affected files are not corrupted, since they open just fine in LyX 1.6.X
that I still had installed. 

Any thoughts?

Cheers,

John

If you're comfortable doing so, post the file here, and see if someone 
can figure out the problem. Alternatively, bisect. I.e., start 
deleting parts of the file until you get something that works. Then add 
stuff back in until you figure out what the problem is.

Sounds like some sort of lyx2lyx conversion error. If you can run LyX 
from a terminal, you should get more error messages, though that won't 
solve the problem by itself. So, alternatively, try posting one of the 
problematic files here, or sending it to me privately, if you prefer, 
and we can try to figure it out.

Is there some magic to get the debug output from the command line? I run:

lyx -dbg

or

lyx -dbg graphics

and get no additional output. Is this logged to a file somewhere?

BTW, I have verified that I can make the problem disappear by rolling 
back to 2.0.2 (well, uninstalling 2.0.3, and then installing 2.0.2).

I experienced something similar when converting some files created on windows.
It turned out, that the last line ended with \end_document but was not 
terminated by eol.
Inserting a new line in such lyx-file with a text editor helped.

This is important info. Many more things may go wrong in this case.

I have no experience with LuaTeX and I don't know whether it works with
the babel greek option at all (and which fonts are used in this case).

Maybe your document loads fontspec after babel and this way overwrites the
selection of LGR-encoded fonts for Greek. 

Do you use some hack to overwrite the font-encoding switch usually done
with \textgreek?

 Done. In my case, Greek (polutoniko)

With LuaTeX, babel (instead of polyglossia) and Unicode (utf8 XeTeX), it
*may* be better not to set the language to Grekk (YMMV).

 a) use the pre-composed Unicode characters in the Greek extended block

 Using insertsymbols works, but it is a pain to use. Copy and pasting
 from external sources does not. I see the proper greek on screen, but
 the characters simply disappear in the pdf.

Very strange. Does this happen to the same characters with the same language
setting?

Characters disappearing in the PDF are usually an indication of an
incomplete font. On screen, the system (or the QT libs or fontconfig, or
X...) use auto-substitution of missing characters in the configured font
with characters from another known system font, xetex and luatex do not have
this nice feature.

Make sure the document text font contains the pre-composed characters in the
Greek-extended Unicode block.

 b) use the LGR transliteration which is described in the babel Greek
   documentation http://mirror.ctan.org/info/babel/babel.pdf

...

 But in order for this to work, some characters need to be considered
 as letters. These characters are , , ~, ‘,
 ’,  and |.

Yes, these are the characters used to mark accents in the LGR
transliteration (except for the single quotes - the corresponding accent
markers are the ASCII chars ` and '.

   There is no need to use ERT (except, maybe for the tilde character).

 This is exactly what I was trying to do, but I cannot get it to work.
 Example:

 If I enter

epim'eleia eato\~u

 and set the language to Greek Poutoniko, this is what I get in the pdf:

 επιμέλεια εατο\ῦ

 which is unsurprising, since the latex code in Viewsource is:

 \foreignlanguage{polutonikogreek}{\textless{}epim'eleia
 \textgreater{}eato\textbackslash{}\textasciitilde{}u}

 (You mentioned probelms with the tilde, but not even the breathing
 accents are correct. and the Latex looks completely wrong)

Sorry, I did not consider LyX' paranoia escaping of text input because
there is no problem using | in the unicodesymbols file (only ~, because
this is no-break space in normal LaTeX, disabled by Babel for Greek but
re-enabled by LyX).

The conversion of , , and | to \textless, \textgreater, and \textbar is
only required with the legacy OT1 font encoding (i.e. never in Greek and
not with LyX's default setting of T1). Write a bug report?

 If, instead, I enter  \textgreek{epim'eleia eato\~u} in ERT, I get
 the expected output

This means you should be fine with ERT for these characters (or
phrases/words containing these characters) and the tilde.
(The \textgreek is inserted by LyX when you set the language.)


   Alternatively, you can look in the file unicodesymbols in the LyXdir to
   see how LyX maps the Unicode characters to LaTeX code.

 c) if you load the LGRX extended font definitions for the Greek LGR fonts
   (http://milde.users.sourceforge.net/LGR/) in the latex preamble, you

 I will have to try this once I get method (b) to work.

With XeTeX or LuaTeX, I recommend

* Use polyglossia instead of babel.

* Use a text font that contains the precomposed Greek characters
  (you can also set up a different font for Greek and Latin in the LaTeX
  preamble, see the fontspec manual).

* Use Unicode characters for the input. (The LGR transliteration does not
  work without legacy 8-bit LGR encoded fonts.)

   There is no need to use ERT (except, maybe for the tilde character).


By LGR transliteration I think you mean the following rules in the
Babel document:

But in order for this to work, some characters need to be considered
as letters. These characters are , , ~, ‘,
’,  and |.

This is exactly what I was trying to do, but I cannot get it to work. Example:

If I enter

epim'eleia eato\~u

and set the language to Greek Poutoniko, this is what I get in the pdf:

 επιμέλεια εατο\ῦ

which is unsurprising, since the latex code in Viewsource is:

\foreignlanguage{polutonikogreek}{\textless{}epim'eleia
\textgreater{}eato\textbackslash{}\textasciitilde{}u}

(You mentioned probelms with the tilde, but not even the breathing
accents are correct. and the Latex looks completely wrong)

If, instead, I enter  \textgreek{epim'eleia eato\~u} in ERT, I get
the expected output


   If you start with method a), you can also use the ViewSource feature to
   see the translation to the LGR transliteration (unless the document
   output encoding is set to Unicode (utf8)).


I am using utf8, so I guess this does not apply.

   Alternatively, you can look in the file unicodesymbols in the LyXdir to
   see how LyX maps the Unicode characters to LaTeX code.

 c) if you load the LGRX extended font definitions for the Greek LGR fonts
   (http://milde.users.sourceforge.net/LGR/) in the latex preamble, you
   can also use standard accent commands (and their extensions) as
   described in http://milde.users.sourceforge.net/LGR/lgrxenc.pdf For
   single accents, this should also work with accent-... LyXfuns + base

I will have to try this once I get method (b) to work.

Can't open files in 2.0.3 (Buffer_convertLyxFormat.hXXXX is not a readable Lyx Document)

[John Enright]

Since upgrading to 2.0.3, Many of my files will not open. I get an error message
during the open operation saying:

C:\Users\myusername\AppData\Local\Temp\lyx_tmpdir.p10476
\Buffer_convertLyxFormat.h is not a readable LyX document.

The temp directory exits (as specified in the message); the temp file is
zero-bytes long.

- I'm running Win7 (x64). My MikTex is up to date. I've reinstalled LyX several
times (including uninstalling it). No difference. 

- Some old files will open. But many will not. Not sure of what is special about
the affected files. Perhaps some particular floats, but I can't seem to
replicate the problem with a new file.

- I can create and reopen a completely new file. 

- The affected files are not corrupted, since they open just fine in LyX 1.6.X
that I still had installed. 

Any thoughts?

Cheers,

John

Sounds like some sort of lyx2lyx conversion error. If you can run LyX 
from a terminal, you should get more error messages, though that won't 
solve the problem by itself. So, alternatively, try posting one of the

Is there some magic to get the debug output from the command line? I run:

lyx -dbg

or

lyx -dbg graphics

and get no additional output. Is this logged to a file somewhere?

BTW, I have verified that I can make the problem disappear by rolling 
back to 2.0.2 (well, uninstalling 2.0.3, and then installing 2.0.2).

I experienced something similar when converting some files created on windows.
It turned out, that the last line ended with \end_document but was not 
terminated by eol.
Inserting a new line in such lyx-file with a text editor helped.

I have no experience with LuaTeX and I don't know whether it works with

Maybe your document loads fontspec after babel and this way overwrites the
selection of LGR-encoded fonts for Greek. 

Do you use some hack to overwrite the font-encoding switch usually done

 Done. In my case, Greek (polutoniko)

With LuaTeX, babel (instead of polyglossia) and Unicode (utf8 XeTeX), it
*may* be better not to set the language to Grekk (YMMV).

 a) use the pre-composed Unicode characters in the Greek extended block
   (drag and drop from somewhere or use InsertSymbols).

 Using insertsymbols works, but it is a pain to use. Copy and pasting
 from external sources does not. I see the proper greek on screen, but
 the characters simply disappear in the pdf.

Very strange. Does this happen to the same characters with the same language
setting?

Characters disappearing in the PDF are usually an indication of an
incomplete font. On screen, the system (or the QT libs or fontconfig, or
X...) use auto-substitution of missing characters in the configured font
with characters from another known system font, xetex and luatex do not have
this nice feature.

Make sure the document text font contains the pre-composed characters in the
Greek-extended Unicode block.

 b) use the LGR transliteration which is described in the babel Greek
   documentation http://mirror.ctan.org/info/babel/babel.pdf

...

 But in order for this to work, some characters need to be considered
 as letters. These characters are , , ~, ‘,
 ’,  and |.

Yes, these are the characters used to mark accents in the LGR
transliteration (except for the single quotes - the corresponding accent
markers are the ASCII chars ` and '.

   There is no need to use ERT (except, maybe for the tilde character).

 This is exactly what I was trying to do, but I cannot get it to work.
 Example:

 If I enter

epim'eleia eato\~u

 and set the language to Greek Poutoniko, this is what I get in the pdf:

 επιμέλεια εατο\ῦ

 which is unsurprising, since the latex code in Viewsource is:

 \foreignlanguage{polutonikogreek}{\textless{}epim'eleia
 \textgreater{}eato\textbackslash{}\textasciitilde{}u}

 (You mentioned probelms with the tilde, but not even the breathing
 accents are correct. and the Latex looks completely wrong)

Sorry, I did not consider LyX' paranoia escaping of text input because
there is no problem using | in the unicodesymbols file (only ~, because
this is no-break space in normal LaTeX, disabled by Babel for Greek but
re-enabled by LyX).

The conversion of , , and | to \textless, \textgreater, and \textbar is
only required with the legacy OT1 font encoding (i.e. never in Greek and
not with LyX's default setting of T1). Write a bug report?

 If, instead, I enter  \textgreek{epim'eleia eato\~u} in ERT, I get
 the expected output

This means you should be fine with ERT for these characters (or
phrases/words containing these characters) and the tilde.
(The \textgreek is inserted by LyX when you set the language.)

With XeTeX or LuaTeX, I recommend

  (you can also set up a different font for Greek and Latin in the LaTeX
  preamble, see the fontspec manual).

* Use Unicode characters for the input. (The LGR transliteration does not
  work without legacy 8-bit LGR encoded fonts.)

There are (at least) 3 ways:

For all methods, you must mark the text in question as "Greek".

a) use the pre-composed Unicode characters in the "Greek extended" block
   (drag and drop from somewhere or use Insert>Symbols).

b) use the "LGR transliteration" which is described in the babel Greek

For quotes that you can drag and drop from somewhere, I recommend a). For
larger input "by hand" without a Greek-Unicode keybord mapping b) might
be more convenient. All methods can also be combined (with some
experimentation).

LyX uses Greek fonts in the LGR font encoding instead of the ibycus
encoding, therefore the input conventions differ.

aspect ratio in figures

[Allen Barker]

I'm having some problems with the aspect ratio of figures
which are inserted into Lyx.  This is with version 2.0.3
on a Fedora 15 system.

I insert a .png screenshot with insert->graphics and set
the width to some value (with the maintain aspect ratio box
checked).  The preview looks fine.  But, when the file is
printed in PDF the aspect ratio is not preserved.  For
example, a square image is stretched too much vertically
(by a very noticeable amount).  Postscript is the same.

If I set both the width and the height then the PDF
comes out as it should.  If I view as LyxHTML then the
size is also correct.

I'm just using the default article style, with no packages
inserted and an empty preamble.

Any ideas what's going on?

Can't open files in 2.0.3 (Buffer_convertLyxFormat.hXXXX is not a readable Lyx Document)

\Buffer_convertLyxFormat.h is not a readable LyX document.

The temp directory exits (as specified in the message); the temp file is
zero-bytes long.

- I'm running Win7 (x64). My MikTex is up to date. I've reinstalled LyX several
times (including uninstalling it). No difference. 

- Some old files will open. But many will not. Not sure of what is special about
the affected files. Perhaps some particular floats, but I can't seem to
replicate the problem with a new file.

- I can create and reopen a completely new file. 

- The affected files are not corrupted, since they open just fine in LyX 1.6.X
that I still had installed. 

Any thoughts?

solve the problem by itself. So, alternatively, try posting one of the
problematic files here, or sending it to me privately, if you prefer,
and we can try to figure it out.

Is there some magic to get the debug output from the command line? I run:

lyx -dbg

or

lyx -dbg graphics

and get no additional output. Is this logged to a file somewhere?

BTW, I have verified that I can make the problem disappear by rolling 
back to 2.0.2 (well, uninstalling 2.0.3, and then installing 2.0.2).

I experienced something similar when converting some files created on windows.
It turned out, that the last line ended with "\end_document" but was not 
terminated by eol.
Inserting a new line in such lyx-file with a text editor helped.

There can be many reasons.

I am afraid, this cannot be solved without a minimal example, i.e. a LyX
file, as small as possible but still showing the problem.

This is important info. Many more things may go wrong in this case.

I have no experience with LuaTeX and I don't know whether it works with
the babel greek option at all (and which fonts are used in this case).

Maybe your document loads fontspec after babel and this way overwrites the
selection of LGR-encoded fonts for Greek. 

Do you use some hack to overwrite the font-encoding switch usually done
with \textgreek?

With LuaTeX, babel (instead of polyglossia) and Unicode (utf8 XeTeX), it
*may* be better not to set the language to Grekk (YMMV).

Very strange. Does this happen to the same characters with the same language
setting?

Characters "disappearing" in the PDF are usually an indication of an
incomplete font. On screen, the system (or the QT libs or fontconfig, or
X...) use auto-substitution of missing characters in the configured font
with characters from another known system font, xetex and luatex do not have
this nice feature.

Make sure the document text font contains the pre-composed characters in the
Greek-extended Unicode block.

Yes, these are the characters used to mark accents in the LGR
transliteration (except for the single quotes - the corresponding accent
markers are the ASCII chars ` and '.

Sorry, I did not consider LyX' "paranoia escaping" of text input because
there is no problem using <>| in the unicodesymbols file (only ~, because
this is no-break space in "normal" LaTeX, disabled by Babel for Greek but
re-enabled by LyX).

The conversion of <, >, and | to \textless, \textgreater, and \textbar is
only required with the legacy OT1 font encoding (i.e. never in Greek and
not with LyX's default setting of T1). Write a bug report?

This means you should be fine with ERT for these characters (or
phrases/words containing these characters) and the tilde.
(The \textgreek is inserted by LyX when you set the language.)

With XeTeX or LuaTeX, I recommend

* Use polyglossia instead of babel.

* Use a text font that contains the precomposed Greek characters
  (you can also set up a different font for Greek and Latin in the LaTeX
  preamble, see the fontspec manual).

* Use Unicode characters for the input. (The LGR transliteration does not
  work without legacy 8-bit LGR encoded fonts.)

Boxing eqnarray

[Merhebi, Bob]

Hello again,

I was wondering whether it is possible to box an eqnarray?

I am usually use the TeX \boxed to box an equation but I can't seem to
be able to box an eqnarray. Is it possible?

Thanks
