I would like to write simple script to take a directory full
of arbitrary graphics files ( gif, jpg, png, tiff, etc ) and
generate constant-pixel-height thumbnails of them all. What's
a simple, small tool that I can install and use for this?
I would really like small/simple rather than a huge beast like
gimp. And of course a CLI is needed. Something that will work
on vanilla linux box ( no kde or the like ) without need
for a GUI.
So- has anyone here actually done this? If so what tool(s)?
Imagemagick is easy enough to drive from the shell.
Hint: 'identify <some image>' will yield info about the image
(including its size [HxW]).
'convert <some image> -geometry HxW <thumnail image name>' will
generate the thumbnail of the specificed size. Both identify and
convert can be used in a shell script and neither are GUI programs.
Both are part of the Imagemagick package.
