Hi all,
I was having some trouble when generating a pdf output with pdflatex
for a document with various figures (pdf graphic files). Some of them
showed in the generated pdf but others didn't. For those not showing,
a blank box with the correct figure size was shown instead.
After some digging, I found that the problem only happened to the
graphic files for which LyX generated a "bb" (bounding box) option for
the \includegraphics LaTeX command. That option is generated when you
change the bounding box size in the graphics-clipping pane.
Some more digging revealed that the problem is that the latest version
of pdftex-def file present in texlive-2017 and also in miktex 2.9 just
ignores the bb option, leaving a blank box, with no error message.
Previous versions of pdftex-def deferred the bb option to the viewport
option (with a warning). In that case the graphic file was included
correctly. So, this problem occurs only with updated TeX installations.
Have anybody else seen this problem?
I may have a workaround, inspired by bug #7910
(https://www.lyx.org/trac/ticket/7910), which I think is related. Rather
than using the "Clipping" tab in the graphics dialog, use the "LaTeX and
LyX options" tab, and in the "LaTeX options" field enter "viewport="
followed by the offsets from lower left for the corners of the clipping
box (same values you would have entered in the clipping dialog). I had
to commit the change, save the document, close it and reload it to get
the new settings to apply, but my test graphic appeared an seemed to
work okay.
