Re: Issues using lyx

2017-06-22 Thread Mr William Balthes 
I am interested in the comment about  windows. I have always been a windows 
user but am not wrapped in windows 10.


Does anyone else have experience of documents changing after there has been a 
windows update when the lyx document has been saved but left open.


A suggestion from the list is that I use linux.


I know nothing about it.  Does it have automatic updates that you can't avoid 
where the system restarts.


Is it more stable and do you avoid the crashes out of the blue and when 
selecting large amounts of text with the mouse.


Does linux still have back-ups and save temp files.


Thank you

William Balthes

I just checked with LyX 2.2.3 on Linux Mint, and the same thing 
happens to me (minus the part about Inkscape, which I do not have 
installed). LyX claims to have the ability to display SVG files 
directly, says it's doing a non-conversion (from == to) and then can't 
convert the file.


I'd be inclined to suspect a missing library, but I have libqt4-svg 
and libqt4-svg:i386 installed, along with a half-dozen other SVG 
libraries. That said, GIMP shows my test file as a blank canvas, and 
the default image viewer will not load it.
Okay, I partially retract what I said. I don't have a lot of SVG files 
lying around, and the first ones I tested (all from the same source) 
generated exactly the same error messages Cris reported.


Just now, though, I tried a few others I tracked down on my drive, 
including some .svgz files provided by LyX (in /usr/share/lyx/images on 
Linux systems) and the only .svg file I could find from LyX 
(/usr/share/lyx/doc/clipart/SVG-Drawing.svg). They all worked fine, as 
did a non-LyX SVG file I found in one of my folders.


So apparently there's something "off" about the SVG files that caused 
LyX to spit up the error messages, and maybe there is similarly 
something different about Cris's images.

To my understanding, we depend on QT to do the convert for us.
For it to work, we have to install the appropriate svg module.
On debian-linuxes the needed packages are:
libqt4-svg (for QT 4.8)
libqt5svg5 (for QT 5.x)
Without this, display of svg-images is not working.

Here are my questions:

  * Which tool is converting my SVG to show on the screen if the log
says "No conversion needed"? Are SVG files now somehow "native" to
LyX 2.2.3?
  * Is it not the SVG -> PNG rule I should be overriding?
  * Why is my SVG -> PNG converter (the one I thought should be
executed) being ignored?

The reason I need to do this is that the rendering of flowed (wrapped) 
text in SVG (something I use quite a lot in figures) is very dependent 
on the converter. Inkscape lets me edit pretty well, but I'd been 
having issues with it hanging and so I switched it to rsvg-convert 
while debugging. That tool doesn't quite handle wrapped text so well, 
as it is a controversial (moving target) part of the standard. See 
http://wiki.inkscape.org/wiki/index.php/Frequently_asked_questions#What_about_flowed_text.3F


My SVG -> PDF (pdf2latex) etc. overrides seem to work just fine when I 
test.

Anymore after what? After an upgrade of LyX?

Have you tried using Insert > File > External Materials and choosing
"Inkscape figure"? I wonder if that will work better for your workflow.

While debugging some issues with SVG converters, I'm a bit confused now. I

Here are my questions:

   - Is it not the SVG -> PNG rule I should be overriding?
   - Why is my SVG -> PNG converter (the one I thought should be executed)
