Thanks a lot for all tipe!
I will use pdftoppm now.
Here is a quick script written on the commandline to do this job.
(I use zsh.)
mkdir PDFviews
cd PDFviews
for i in ../*.pdf ../*.PDF
do
fn=${i:r}
fn=${fn:t}
fn=${fn}.png
pdftoppm -f 1 -l 1 $i > tmp.ppm
ppmtojpeg < tmp.ppm > $fn
done
rm -f tmp.ppm
Have a nice sun(ny)day !
