OK, not the most useful but a good way to impress friends. Requires the "display" command from ImageMagick.

convert {$file_in} \( +clone -background black -shadow 60x5+10+10 \) +swap -background none -layers merge +repage {$file_out}

Please take notice that if you are going to use an JPG file for shadow effect,

let change -background none to -background white!

Because -background none make a transparent effect while JPG doesn't support transparent! And when viewing, you will get a bacl box!

So we will use an white background under! We can use other color as well!

Requires ImageMagick. Takes a screenshot 5 seconds after it's run and saves it as desktop_screenshot.jpg Particularly handy when made into a menu option or button.

Create a favicon suitable for use on your web site. Note: ppmtowinicon is part of libpbm, not ImageMagick.

On Debian systems, displays a graph of package dependencies. Works also with other image formats, like svg :

This command requires the imagemagick libraries and will resize all files with the .jpg extension to a width of 1024 pixels and will keep the same proportions as the original image.
