Paul:
I don't understand this. You're saying that LyX will display the PPM
file properly (if you include it directly in the document) but GIMP
thinks the file is bad?
LyX displays the ppm file but not properly. I mean, it appears an
image on the screen, but this image has less to do with the original
ps figure. Therefore, ImageMagick is converting the ps file into a ppm
file containing some strange information that LyX is able to display
but GIMP is not able to open ("plugin cannot open image")
Do you have problems converting non-Adobe formats (e.g., figure1.jpg)
to PPM? The reason I ask is that ImageMagick relies on Ghostscript
when converting Postscript and Encapsulated Postscript to other
formats. So if the problem is only with PS/EPS and not with
JPG/PNG/..., then the place to look is your Ghostscript installation.
If I run
convert figure1.ps figure1.jpg
and then
convert figure1.jpg figure1.ppm
then both jpg and ppm files are correctly converted (I am able to open
them in GIMP) and LyX displays the ppm file without problems. However,
if I try to load the jpg file in LyX then I get the "Error converting
to loadable format". So I believe that the problem is not with
Ghostscript.
Meanwhile, I'm not sure any of this explains your problem entirely,
particularly since you indicated conversion to PPM (the format LyX uses
for internal display) failed for all sorts of image types. You might
try the following. Open a DOS window and cd to the LyX bin directory.
Run 'lyxc -dbg graphics' there. (Note that it's lyxc, not lyx.) Start
a new document. The DOS window will have all sorts of progress
messages from LyX that we don't care about; make a note where they end.
Now insert an image with the option to display in LyX turned on. More
messages will spew into the DOS window. Copy the ones that came after
you inserted the image and mail them to the list; maybe they'll tell us
where the script is failing.
