Description

I have images that are 768x1200, and I want to add black bars to them so that their resolution is 1920x1080. How do I do that?

Your input is taller than your output. Just adding black bars won't do that.

As snibgo says, your input is 1200 px tall but you want your output to be 1080 px tall, which is smaller than the input. Are you willing to crop the input so that the output can be 1080 in place of 1200 or do you want to shrink the input height using by resizing it, then add black bars to fill the width?

Shrink the input.

try

magick input.suffix -resize "1920x1080^" -gravity center -background black -extent "1920x1080" output.suffix

escape the ^ as appropriate for your OS, if needed.

Note: I edited to add -gravity center. See above

Didn't work. It only cut out important parts of my image.

[fmw42]

Post your input image so I can examine it and then test with it and correct my command

Here is it.
