All of the "convert" options can be found here.
Using GraphicsMagick to crop an image, you can either use "crop" or "shave". Use crop if you want to specify the size of the cropped image, or use shave if you want to specify the amount to remove from the edges.
So, if you want to take an 800x600 wallpaper and make an 800x480 version of it by just cropping the centre of the image, do this:

Unfortunately, qole's example works only in ImageMagick, not in GraphicsMagick since GraphicsMagick does not support the +repage option. But the command works if you remove that option.

Manpage: gm convert
Here's an example that fetches a big image, resizes it to 800 pixels wide, crops it to 800x480 centered, "flops" it (left-to-right), and displays the final result:

thanks, terrancegf,
I tested that in ImageMagick, not GraphicsMagick. I personally don't understand why IM doesn't work the way that GM works. You should be able to use "-gravity Center" and it should just work. So GM works "as expected" for me...
Thanks again for this port. What's the installed size?
