convert to jpegs

[Brian Henning]

Greetings,

i have a bunch of files of different image formats that i would like to convert
to jpeg.
is there a command line converter to be able to do them all in one shot?
maybe with xv or xnview?

Thanks,
brian

But it to slow. Maybe gd will be more faster.
I think there is interesting which is `different image formats`

I'd like such variant
--cut-here--
#!/bin/sh

process_dir() {
for F in $1/*; do
if [ -d "$F" ]; then
process_dir "$F"
else
JF=$(echo "$F" | sed 's/\.[^\.]*$//')
case "$F"; in
*.gif) gif2jpg "$F" > $JF ;;
*.pnm) pnm2jpg "$F" > $JF ;;
*.png) png2jpg "$F" > $JF ;;
esac
fi
done
--cut-here--
or something like this

ImageMagic is one route; the URT or netPBM toolkit the other. With the
latter two you can do

for i.tiff in *
do
j=`basename $i .tiff`
cat $i tifftopnm | pnmscale 0.5 | cjpeg > $j.jpg
done

and so on. Combined URT and NetPBM support just about any format.

The Utah Raster Toolkit (urt) is a bit more advanced and very suitable for
scientific work where values and geoms are important; for visual work
netpbm is just fine.
