I need to take a spinner gif and add text to it, but the text needs to be under the spinner animation, below the border of the current image.
Is there a command to add transparent space around an image with Imagemagick? Alternatively, is there a free online tool to achieve the same result?
I tried the following, but it creates a very jittery and unusable image:
convert spinner.gif -background none -gravity north -extent 400x200 new_spinner.gif
