Imagemagick is made up of a bunch of commands like mogrify and convert
(there are more, I think). A lot of times I just use mogrify to resize,
but convert will do resizing too.
The basic command for resizing is:
mogrify -geometry WxH image.png
where W is width and H is height (in pixels). Note that this will
overwrite the image, so if you want to keep the originals, be sure to
copy them.
If the aspect ratio doesn't allow you to resize in the dimensions you
want, use ! to force the size (distortion will occur), i.e. -geometry
40x35! .
Doing this in batch depends on the picture names and whether you've got
spaces in the names (or the folders). With no spaces in names or
folders, something like
for image in `find /path/to/search -type f -iname '*.jpg' -o -iname
'*.png'` # (whatever extension(s) you need)
do
mogrify -geometry 16x16 "$image"
done
should do the trick. Find will recurse directories for you; the only issue
is if filenames/folders have spaces in them.
