Resizing *many* images?

Hi everyone,

Does anyone know if there is a way to 'batch resize'? - I have about 1000 images that all need to be 20% of the original size...

Many thanks!

In ksh and I think it works in bash too:

for fn in $(

convert -resize 20% $fn 20-${fn} done

listoffiles is a file containing the names of the files you want to convert. If you can define them any other way (name, location) substitute that for the file.

man ImageMagick
man convert
man mogrify

etc.

ImageMagick is your friend for this kind of job. It will convert batches of images with a simple command line interface.

For example:

for pic in *.jpg do
convert -resize 20%x20% $pic small_$pic done

HTH,

for i in ; do
convert -scale 20% $i small_$i
done

(in other words, I'd use ImageMagick).

Cheers, Dave.

If you want to stay inside Gimp, try David's Batch Processor (DBP) at http://members.ozemail.com.au/~hodsond/dbp.html It provides the most common operations, lets you set up the effect you want, then runs all your files through the same processing. Linux only, I'm afraid, although I believe there's a Windows version somewhere on the Web. Current version is for Gimp 1.2, but I've got the Gimp 1.3 version nearly ready to go.

Great, that worked out just fine, thanks!

Much obliged ;-)
