I was looking for how to get the image’s (JPEG, PNG, TIFF) PPI value and all the solutions I found look something like this:

identify -format "%x x %y" foo.jpg

This works, but what I don’t understand is why there is % in the end of its output?

72 x 72%

144 x 144%

and so on. Is it because the command’s syntax should be somewhat different?
