Astonishing, because pdflatex can embed pdf's directly without conversation
yes I thought that.
Did you tried it again with the fixed paths (no umlauts, no spaces)?
I finally got it to switch to eps, thus these problems are not anymore as I can use eps instead of pdf.
But eps pumps up unnecessarily the size of your pdf.
But I encountered two further strange things on the way to this solution:
(1) lyx or something associated with handling eps in lyx/latex is sensitiv to filenames or paths. eps was not handled correctly if the files (.lyx, .eps) were on a different partition inside a path with German "Umlaute" (ü, ö, ä). I never had problems with that, it does not seem to be lyx specific but an eps issue, but after moving the .lyx/ .eps files directly into the lyx-path, the problem disappeared at once without changing the lyx-file
This is a known problem of LyX, but should be fixed now in LyX 1.3.5. (not available under win :-( )
(2) eps is NOT eps, i.e. there is no eps preview possible if the eps is made by different apps like Visio, CorelDraw, CorelPresentations etc. under win32. Only if the following procedure was chosen, it succeeded:
-> print into ps (with embedded eps checked in postscript settings via virtual laser-printer)
-> convert to eps via ghostview
some of these eps (visio, Corel, etc.) were not only unavailable in lyx-preview, but could not be handled to be transformed into dvi/pdf, too.
There were no problems regarding the classic method of ps -> eps
But ghostview was able to open all eps made by visio, corel.
This isn't a problem of LyX. LyX uses Imagemagick to process images and Imagemagick uses Ghostscript to process pdf, ps and eps images. I've also had some problems with these image formats and the Imagemagick developers often had a fast fix.
You should update to an actual Imagemagick (at least version 6.1.x) and to AFPL Ghostscript 8.14.
But it's also possible, that the eps are produced with errors. Just today, I wanted CorelDraw 10 to export a file to .eps and it often crashed after producing broken eps-images.
