Add border to top of image using imagemagick

I have an image 100x40 and I want to add a border to the top of the image 10 pixels high.

I've found 

convert source.jpg -border 0x10 out.jpg

but this adds a border to the top and bottom. Is there anyway to add it to only the top?

Solution

  • Use -splice:

    convert source.jpg -splice 0x10 out.jpg

    If you want to add the border only at the bottom, use -gravity as well: convert source.jpg -gravity south -splice 0x10 out.jpg

    Note that the border will be transparent, unless you use -background, too.
