resizing a set of images
Morning,
I remember someone else having asked something similar to the question I have, but I looked and looked but couldn't find it, so I'll ask again:
Is there a way to resize a set of images all at once, instead of editing
them one by one?
And if this can't be done with The Gimp, is there another program I could
use?
I have about 100 images, and it would take far too long to start resizing each one individually.
Thanks. -Nasim Sh.

Stock answer #317:
Use 'convert' from the ImageMagick set of utilities.
Cheers, Malcolm

Alternative answer, for the command line impaired: try dbp. http://www.ozemail.com.au/~hodsond/dbp.html

Nasim,
Gimp can do this function too, but ImageMagick is much easier and
quicker to use for such things.

Hi,
here are a few scripts that may be usefull
sorry it is a little bit long
create a txt file copy the script in it
type chmod 755 the_name_of_the_file
put the file in /usr/bin
and use the cript from the folder containing the files
#!/bin/bash
for i in *jpg
do
# rotate the file and change its name to temp.jpeg
put here one of the line starting by convert that is in between the~~~~~
# remove the file rm "$i" ;
# give temp.jpeg the file name mv temp.jpeg $i ;
done
~~~~~~~
#land2portrait 90 CCW
convert -rotate "-90>" "$i" temp.jpeg;
#land2portrait 90 CCW convert -rotate "90>" "$i" temp.jpeg;
#port2land 90_CCW convert -rotate "-90" "$i" temp.jpeg;
#portrait 180 convert -rotate "-180" "$i" temp.jpeg; ~~~~~~~~
this file allows you to create a web page (W3C compliant) with thumnails of pictures as link to the same pictures.
you may need to have to adjust the file if the mail system screwed up by adding carriage returns
you will find there commands to resize images

Good Morning...
well.. there is of course Irfan View, which can do
batch conversion of files, including the function you
want (resize) plus lots of other useful functions
(rotate, apply a filter, ... etc)...
u can find it at www.irfanview.com
