LyX 2.3 and 2.4 have troubles displaying EPS images

Wed Feb 9 01:06:17 UTC 2022

Dear list,

A friend of mine noticed that LyX 2.3 has problems displaying the attached
EPS file. All other EPS images can be previewed within LyX without any
problem. All EPS files are displayed correctly in the PDF (produced by
pdflatex). I can reproduce this issue with LyX 2.3.6.1. Both of us are
using Windows x64 (Windows 8 for her, Windows 10 for me). LyX shows the
following error message (within the preview box):

Error converting to loadable format

This EPS is quite large (almost 40 MB). All the other EPS files for the LyX
documents are at most 2 MB (and they all display correctly). It was
generated with Photoshop (which certainly explains the size).

Here is the way paths are configured (my MikTeX installation is totally up
to date):

[image: image.png]

C:\Users\Thibaut\AppData\Local\Programs\MiKTeX\miktex\bin\x64;$LyXDir\bin;$LyXDir\Python;$LyXDir\Python\Lib;$LyXDir\imagemagick;$LyXDir\ghostscript\bin

Here is the relevant part of the LyX document (with text edited for
brevity):

\begin_layout Standard

\begin_inset Float figure

placement t!

wide false

sideways false

status open

\begin_layout Plain Layout

\align center

\begin_inset Graphics

filename graphics/undisplayable.eps

width 60line%

\end_inset

\begin_inset Caption Standard

\begin_layout Plain Layout

Caption

\end_layout

\end_inset

\end_layout

\end_inset

\end_layout

With the same document as hers, with the development version of LyX,
however, I get more problems with previewing any image: they all show "
Error converting to loadable format", be they EPS or PDF. I thought it
could be a problem of paths, but they are configured in the same way as my
LyX 2.3 installation (with the exception of LilyPond -- removing it does
change anything).

C:\Users\Thibaut\AppData\Local\Programs\MiKTeX\miktex\bin\x64;$LyXDir\bin;$LyXDir\Python;$LyXDir\Python\Lib;$LyXDir\imagemagick;$LyXDir\ghostscript\bin;C:\Program
Files (x86)\LilyPond\usr\bin

The console output doesn't say anything about the issue, it mostly
complains that it cannot find Git:

Do you have any trick to debug this further? For the LyX 2.3 issue, it
might be a timeout for large EPS; for 2.4, I have no idea.
