I'm trying to add padding to the top of an image using the command line.
I've found the
sips command and I've tried
sips --padToHeightWidth 1300 1920 image.png
on an image which is 1920 x 1080.
However this adds 50px of padding to the top and bottom.
Is it possible to just add 100px of padding to the top?
Is there another tool I should/could be using to do this?
