    Batch image editing?

    I love the Tango icon theme for it's simplicity and uniformity, but I'm really tired of all the blue. I was thinking it would look nice if I could fade them all out to grey (reduce saturation, convert to black and white, etc.) and use them with one of the many nice grey gtk themes. But there's a TON of these things! Is there an app that I can just point at the theme directory and have it take care of this automatically?

    The app you are looking for is called ImageMagick and I believe it's already installed in Dapper.

    The command to perform a conversion is 'convert'. You can find many examples on the official ImageMagick site.

    Here is an example:

    convert -modulate 100,0 input.png output.png

    This will reduce saturation of image input.png to 0, and create image output.png out of it.

    Sorry for the mega-kick, but it's better than opening a new topic, I'd say.

    Basically I want to do the same as the topic-starter. My theme looks really nice now, but I want the applet-icons to be grey, that would finish it. So what I have to do is select all files in /usr/share/icons, and all files in the subfolders in that, and saturize them.

    Can someone give a detailed how-to for that?
