"Error converting to loadable format" when I insert an eps file into
a lyx document.
I am starting to think  there may be a problem with latex, dvips or
convert.  Here is what I have done
latex approx-pic.tex
dvips approx-pic -E -o approx-pic.eps
I then tested by hand (assuming that is roughly what lyx does)

convert approx-pic.eps pic.jpg
   

You're confused.

1. latex can handle eps files fine. No conversin needed.
2. pdflatex requires either pdf files (preferable as they retain the 
vector graphics info) or png/jpg files (bitmapped versions of the 
oiginal).
3. The preview you see on the lyx screen is generated from a format 
loadable by the gui-library. Either xforms or qt. Neither can load 
eps files natively, so we invoke a conversion step to a loadable 
format behind the scenes.

 

and I get
   

 

Unrecoverable error: rangecheck in .putdeviceprops
Unrecoverable error: rangecheck in .putdeviceprops
convert: Postscript delegate failed [No such file or directory].
   

 

What should I do?
   

As stated above, you don't need any conversion step to enable the 
latex compiler to handle eps files. More generally, if you believe 
that your version of convert is broken then I guess you should file 
bug report with either Fedora or ImageMagick.

Incidentally, does 
$ gs approx-pic.eps
work?

 

Thanks for the reply. I think we must have misundestood each other. 
1) I know latex can handle eps files. I ran the steps I showed to try to 
debug the lyx problem.   However see below...
2) I'm not using pdflatex at all. I am using View->Postscript in lyx
3)

" The preview you see on the lyx screen is generated from a format

Right. I was trying to pinpoint the error by assuming that this used convert to show the eps file in lyx.

The crucial points are these.

a) lyx preview does not work. It gives the conversion error I mentioned in the previous email. 
b) View->Postscript does not work. It gives

which is the division by zero error I reported last week.
