converting images with command "convert"?

[raptor]

I have a cd full of images that i would just like to convert all of them to a certian resolution. How would i go about converting a whole cd of images to .png format and a screen resolution of 1024x768?

Thanks!

Hmm, I would think something like this should do it:

Code: Select all

$ mkdir ~/pics
$ cd /mnt/cdrom
$ for i in `find | egrep -i ".jpg$|.gif$"`
> do
> convert -resize 1024x768 $i ~/pics/${i%%.[jJgG][pPiI][gGfF]}.png
> done


That should convert any gif and jpg files to png, resize them to 1024x768 and put them in your ~/pics directory. It should work, however there may be problems if you have spaces in your filenames. That can be worked around by adding some quotes. It also won't keep whatever subdirectory structure you have on your CD (it will put all the png files in one directory) so the names must be unique. That could be worked out as well.
