 You're in trouble here. Try typing return to proceed.
 If that doesn't work, type X return to quit.

 As I mentioned above, the exact same LaTeX code does exactly what I  
 want when placed directly in the preamble and used with ERT.

I suspect that the \newfontfamily command is put in preamble before the 
\usepackage{fontspec}. Since this is a command of that package, you need to 
load the fontspec package from the module.

Try

InsetLayout CharStyle:Greek
LyxType   charstyle

LatexType command

  \RequirePackage{fontspec}
  \newfontfamily{\G}{Lucida Grande}

pdf font quality improvement after miktex update

[asm23]

Hi, I'm using Lyx and Miktex 2.7 in Windows.

I notices that in the Lyx preamble, there are some code like below:

 % set fonts for nicer pdf view
\IfFileExists{lmodern.sty}{\usepackage{lmodern}}{}

This will give a nice font view in pdfLatex(the font looks heavy black).

If I didn't use these code, the font in the generated pdf was light and 
looks ugly.


Since I update my Miktex to the latest package yesterday, I found this 
difference has gone, both cases will give a nice pdf. So we don't need 
these statement in preamble any more.


Can someone tell me the reason? Why?

Thanks.

Graphics output on PDF

[Pablo]

Hello everybody!

I'm working on a thesis, currently running Lyx 1.6 over MikTex 2.7 on a Vista
environment. Just in case I'm using the standard Report layout. When
generating the PDF via pdflatex everything looks pretty except for the graphics.
Eventhough they look pretty good on Lyx, on the pdf they appear completely
oversized and since I am mostly working with raster images (I mean, not
vectorial) they look pretty bad. So, for every figure I add, a process of trial
and error follows in order to get the right scale.. (then of course I have to
determine the right clipping values in order to get the image centered!)...

I have the impression that lyx would work much better with vectorial images
(eps, svg, etc.) but most of my figures are made with Flash.. and sadly its
fuction for exporting vectorial images doesnt work too well..


Anyway, any ideas of whether there is something wrong here? 

Thank you very much in advances!

SVG conversion to pdf produces bitmaps

[Stefano Franchi]

Hi all,

I know this issue has been discussed repeatedly, but rereading the old threads 
and the wiki pages did not provide any help.

Problem: I have a small illustration produced with Inkscape and saved as SVG. 
When I insert it into LyX as SVG, it gets converted to a bitmapped image both 
in the LyX preview (which I don't care about) AND in the pdf output (which I 
DO care about).
The SVG image looks all right when loaded into an SVG-aware app (e.g. 
FIrefox).

What I did:

1. I followed the instructions on the wiki and added format and converters for 
SVG and SVG--EPS, SVG--PDF, SVG--PNG

Result: bitmaps both on screen and in Pdf

2. As suggested  in an older  thread, I tried removing the SVG--PNG 
converter.

Result: as above


My setup is: Lyx 1.6.2 on Linux (Kubuntu 9.04) and Inkscape 0.46. I use 
pdflatex to compile to pdf.



Thanks for the help,

S.

Float placement with SWeave

[Graham Smith]

Can anyone give me some hints about float placement of figures created 
with SWeave. 

I have tried a float and a wrap float,  but the former seems to put the 
floats one per page, and the latter seems to end up with text running 
through the figure.


Is there a standard way of doing this, or do I just have to keep fiddling.

Of course this migt be more my inexperience wth Lyx rather than SWeave, 
but normally with a figure,  I can alter the size of the figures, to 
find an optimum size for the float, but with SWeave, the float doesn't 
contain the figure, only the code to create the figure in R, so this 
isn't an option.


This is Lyx 1.6.2 on a Mac with tiger.

Many thanks,

Graham

Strange.

Some more trials:

* Convert to Postscript.

* Try the used converter-scripts from a command line and have a look at
  the produced eps and pdf file.
  
* remove the SVG-PDF converter and try PDF and Postscript generation.

* (add SVG-PDF again and) remove the SVG-EPS converter and try PDF and
  Postscript generation.
  
* use a different flavour of PDF (pdf, pdf1, pdf2) as end-format of the

* Maybe also FileExportPS/PDF and have a look at the generated graphics

I'd try to clip the margins already when producing the image or with some

That's not true. When you use the default fonts, you still get the font Computer Modern. You'll 
see this in the PDF when you zoom to 800 - 1200 % - the font is pixeld. When you go to the PDF 
document properties, you can see that the used font type it Type 3 which is a bitmap font, see 
attached.

That may be it. Inkscape seems to fail the SVG -- PDF conversion in batch

upgrade to the latest SVN version to see if the problem is solved. 

It seems, however, that, even when working, the Inkscape Cairo-based routines

summer 2008:

It doesn't support Patterns, Clipping, and Masks and

Is anyone encountering these kind of problems?

Well it seems that it will be kind of open, so I guess one _could_
write something on the server-side that translates something wave-y to
LaTeX, and from there to PDF/PS/whatever. But it would not be LyX...
(cause I think it would be insane to try to port the whole LyX
interface to Wave).

I suspect that the \newfontfamily command is put in preamble before the 
\usepackage{fontspec}. Since this is a command of that package, you need to 
load the fontspec package from the module.

Try

InsetLayout CharStyle:Greek
LyxType   charstyle
LabelString   greek
LatexType command
LatexName grk
Preamble
  \RequirePackage{fontspec}
  \newfontfamily{\G}{Lucida Grande}
  \newcommand{\grk}[1]{\G #1}
 EndPreamble
End

InsetLayout CharStyle:Hebrew
LyxType   charstyle
LabelString   hebrew
LatexType command
LatexName heb
Preamble
 \RequirePackage{fontspec}
 \newfontfamily{\H}{Lucida Grande}
 \newcommand{\heb}[1]{\H #1}
EndPreamble
End

pdf font quality improvement after miktex update

[asm23]

Hi, I'm using Lyx and Miktex 2.7 in Windows.

I notices that in the Lyx preamble, there are some code like below:

 % set fonts for nicer pdf view
\IfFileExists{lmodern.sty}{\usepackage{lmodern}}{}

This will give a nice font view in pdfLatex(the font looks heavy black).

If I didn't use these code, the font in the generated pdf was light and 
looks ugly.


Since I update my Miktex to the latest package yesterday, I found this 
difference has gone, both cases will give a nice pdf. So we don't need 
these statement in preamble any more.


Can someone tell me the reason? Why?

Thanks.

Graphics output on PDF

[Pablo]

Hello everybody!

I'm working on a thesis, currently running Lyx 1.6 over MikTex 2.7 on a Vista
environment. Just in case I'm using the standard "Report" layout. When
generating the PDF via pdflatex everything looks pretty except for the graphics.
Eventhough they look pretty good on Lyx, on the pdf they appear completely
oversized and since I am mostly working with raster images (I mean, not
vectorial) they look pretty bad. So, for every figure I add, a process of trial
and error follows in order to get the right scale.. (then of course I have to
determine the right clipping values in order to get the image centered!)...

I have the impression that lyx would work much better with vectorial images
(eps, svg, etc.) but most of my figures are made with Flash.. and sadly its
fuction for exporting vectorial images doesnt work too well..


Anyway, any ideas of whether there is something wrong here? 

Thank you very much in advances!

SVG conversion to pdf produces bitmaps

[Stefano Franchi]

Hi all,

I know this issue has been discussed repeatedly, but rereading the old threads 
and the wiki pages did not provide any help.

Problem: I have a small illustration produced with Inkscape and saved as SVG. 
When I insert it into LyX as SVG, it gets converted to a bitmapped image both 
in the LyX preview (which I don't care about) AND in the pdf output (which I 
DO care about).
The SVG image looks all right when loaded into an SVG-aware app (e.g. 
FIrefox).

What I did:

1. I followed the instructions on the wiki and added format and converters for 
SVG and SVG-->EPS, SVG-->PDF, SVG-->PNG

Result: bitmaps both on screen and in Pdf

2. As suggested  in an older  thread, I tried removing the SVG-->PNG 
converter.

Result: as above


My setup is: Lyx 1.6.2 on Linux (Kubuntu 9.04) and Inkscape 0.46. I use 
pdflatex to compile to pdf.



Thanks for the help,

S.

Float placement with SWeave

[Graham Smith]

Can anyone give me some hints about float placement of figures created 
with SWeave. 

I have tried a float and a wrap float,  but the former seems to put the 
floats one per page, and the latter seems to end up with text running 
through the figure.


Is there a "standard" way of doing this, or do I just have to keep fiddling.

Of course this migt be more my inexperience wth Lyx rather than SWeave, 
but normally with a figure,  I can alter the size of the figures, to 
find an optimum size for the float, but with SWeave, the float doesn't 
contain the figure, only the code to create the figure in R, so this 
isn't an option.


This is Lyx 1.6.2 on a Mac with tiger.

Many thanks,

Graham

The SVG->PNG converter is not needed.

Strange.

Some more trials:

* Convert to Postscript.

* Try the used converter-scripts from a command line and have a look at
  the produced eps and pdf file.
  
* remove the SVG->PDF converter and try PDF and Postscript generation.

* (add SVG->PDF again and) remove the SVG->EPS converter and try PDF and
  Postscript generation.
  
* use a different "flavour" of PDF (pdf, pdf1, pdf2) as end-format of the
  SVG->PDF converter.

* Maybe also File>Export>PS/PDF and have a look at the generated graphics
  file.

I'd specify the width in absolute units or as percentage of the
textwidth.

I'd try to clip the margins already when producing the image or with some
image editor. Centering can be done with \centering as ERT (raw LaTeX)
before the image.

You checked the vector graphics option, right?  (Just to be sure.)

My setup is: Lyx 1.6.2 on Linux (Kubuntu 9.04) and Inkscape 0.46. I use 
pdflatex to compile to pdf.




I ran into this with LyX 1.6.1 on XP (Inkscape 0.46).  The reason for 
the bitmaps is that Inkscape is failing silently during the conversion, 
and so LyX is falling back on the generic conversion utility, which does 
not grasp SVG.  I'm not sure I ever figured out why it happened on XP, 
but adding the Inkscape directory to the system command path (and 
removing it from the LyX path prefix) seemed to fix it.  (I also used 
the Linux converter syntax:  '--export-pdf=$$o' rather than just 'PDF'.)


I just checked on my office machine (Ubuntu 9.04, LyX 1.6.2) and the 
Linux instructions from the wiki seem to work ok.  You might want to run 
'which inkscape' in a terminal just to be sure that LyX (or Python, as 
the case may be) can find Inkscape.  As Guenter suggested, you should 
also try 'inkscape --export-pdf=myfile.pdf myfile.svg' in a terminal to 
make sure the conversion works outside LyX.

That's not true. When you use the default fonts, you still get the font "Computer Modern". You'll 
see this in the PDF when you zoom to 800 - 1200 % - the font is pixeld. When you go to the PDF 
document properties, you can see that the used font type it "Type 3" which is a bitmap font, see 
attached.



Can someone tell me the reason? Why?


Have you used another PDF viewer of upgrades the existing on?

That may be it. Inkscape seems to fail the SVG --> PDF conversion in batch 
mode. It seems to be a known bug of version 0.46 (the latest version, I 
believe). At least the Inkscape bugtracker reports a known bug in version 0.46 
for the opposite conversion path in batch mode (PDF-->SVG). I will try to 
upgrade to the latest SVN version to see if the problem is solved. 

It seems, however, that, even when working, the Inkscape Cairo-based routines 
to convert to Pdf leave a lot to be desired, From the Inkscape dev list in 
summer 2008:

It doesn't support Patterns, Clipping, and Masks and 
evince won't display the gradients with transparency correctly but 
Acroread will. 
 

Is anyone encountering these kind of problems?

S.

Yes, you are right. And I'm sorry I was wrong.

The empty preamble Lyx document will give a "Type 3" bitmap font.

If I use " % set fonts for nicer pdf view
\IfFileExists{lmodern.sty}{\usepackage{lmodern}}{} " code, the generated 
  pdf has "Type 1" vector font, which is nicer and high quality.


Thanks for your time and your help!

The attachment was the screenshot of the pdf files after zoom to 1600%.
