Problem opening beamer document with 2.1.0
Hello, I have found a problem while migrating from 2.0.7 to 2.1.0. The beamer slides that I'm working on cannot be opened in the new version. It seems to be connected with the new layout. I tried to specify in the document to use the old (local) layout but I had no success in opening the files. I extracted a portion that reproduces the problem. Thanks in advance, Pietro Cortese bugreport.lyx Description: application/lyx

I tried to specify in the document to use the old (local) layout but I had no success in opening the files. The problem are the {} in the Block titles. The conversion routine assumes that opening and closing brackets are in two separate TeX mode insets. But you can also just remove them, and the file will be converted.

Small conversion issue with beamer
Hello, I have found a small conversion issue from lyx 2.0 to 2.1. In 2.0 one could define blocks and, for what I could tell, the block title was to be specified with ERT. In 2.1 one can insert the block title and the ERT text is now interpreted as part of the block. You can find in attachment the same document compiled with lyx 2.0 and lyx 2.1. I wrote a small awk script to correct the problem.

Re: Calculations in lyx
Hello, It would be nice to have the possibility of making calculations in lyx. >From time to time I make some table in excel or openoffice with some calculations and then I copy the numbers to lyx. Then I update something on the table and I have to update also my document. I saw that tex has some computation features but only fixed point. It would be great to have some (c like) computing in lyx with variables and putting in some inset printf("%5.3f", myvariable) and when you close the inset the result appears and gets updated every time you save or export the document. Thanks in advance, Pietro
Image resolution in preview
Hello, I need often to look in detail at a graph that I recently imported into lyx. The resolution of the displayed image is poor (e.g. when you import a pdf image). In order to improve this I tried to modify the line "opts" of the file /usr/share/lyx/scripts/convertDefault.py into for example opts = "-depth 8 -density 144x144". The image improves, however the clipping is messed up. Could it be possible to use the screen resolution parameter not only for fonts but also for images? Alternatively the "scale on screen" image could change the resolution of the displayed image and not scale a low resolution one. It would be also nice if the clipping dialogue would be improved to provide istantaneous previews as soon as a new number is put into the bounding box. It would also increase the productivity if one could have also some arrows to increase or decrease each bounding box parameter to avoid typing numbers. Thanks in advance, Pietro Cortese
Small problems with figure previews
Hello, I'm including some figures in a lyx and I would like to have a preview with better resolution. I'm using a lyx file as a logbook and I would like to see clearly pictures and included documents. Picture scaling increase the dimension but not the resolution. I tried to add a new converter in Tools-File-handling-Converters from PDF to png but it didn't work. Only solution seems to be to put the picture inside a preview box. Another problem is when including external material with pdfpages. If you specify for example in the latex options "pages=4" in the preview you see always the first page. In this case if you include the pdfpages inside a preview box you get an error message on output Warning: Failed to produce 1 preview snippet(s). Please could you give me some suggestion? Many thanks, Pietro
Missing Glyphs! error
Hello, when compiling the attached document with pdflatex in lyx2.2.1 or lyx2.2.0 I get the error message: Missing Glyphs! Missing character: There is no ; in font nullfont! However if I open the containing directory and compile by hand the tex file with pdflatex there are no errors. When opening the same document in lyx2.1.5 it compiles without problems. It is a very weird situation. Please could you have a look? Thank you in advance, Pietro Cortese broken_in_2.2.lyx Description: application/lyx
Re: Small problems with figure previews
Hi Scott, yes I'm referring to the image displayed in lyx that has low resolution and becomes unreadable. Scaling the image makes it bigger but does not improve resolution. Bu running lyx 2.2.1 in debug mode I see that the image is first converted from pdf to eps and then loaded into cache graphics/GraphicsCacheItem.cpp (265): Image conversion succeeded. graphics/GraphicsCacheItem.cpp (295): Loading image. graphics/GraphicsCacheItem.cpp (301): Image loading succeeded.

Hi Pietro, To make sure I understand, you are only referring to LyX's display right? i.e. there is no problem with the final PDF output? What is your LyX version? You can run LyX as lyx -dbg graphics to get more information about graphics conversions. Scott
Re: Small problems with figure previews
The converter to pdf to eps in my setup is: pdftops -eps -f 1 -l 1 $$i $$o this probably explains why when using pdfpages material the preview in lyx is always the first page. However this conversion preserves resolution. The loss of resolution should be downstream of the conversion. Best regards, Pietro
Re: Small problems with figure previews
Dear Scott, I send you an example that on my system (Centos 7) shows the problem. newfile2.pdf is included bt newfile1.lyx and the text displays correctly in the output but on my system does not display well in lyx.

Fwd: Re: Small problems with figure previews
Forwarded Message Subject:Re: Small problems with figure previews Date: Sun, 18 Sep 2016 18:03:29 +0200 From: Pietro Cortese To: parubi...@gmail.com, skost...@lyx.org Hello, for some reason I'm not receiving e-mails from you and I didn't see the screehsot. I had left the scaling to 150% in the example. However even with 100% the result is not very easy to read. The result seems to be independent on the fact that I put "convert $$i $$o" or "convert -density 300 -units pixelsperinc $$i $$o" in the eps to png conversion. I have the impression that convert is not called. I renamed /usr/bin/convert to /usr/bin/convert-no and the picture is loaded anyway. Pietro
Re: Fwd: Re: Small problems with figure previews
Hello, by using the debugging option as you suggested and looking in the code the issue became clear. With QT4.8 lyx is using QT for conversion and therefore the suggestion to change the converter settings didn't work. I recompiled with QT5 and now it is using the external converter and therefore the suggestion: convert -density 150 $$i $$o does the trick. Thanks, Pietro
