I need to process a set of identically formatted images to get them to conform with my client's website format. I wanted to use ImageMagick's convert or mogrify instead of ffmpeg but I just cant make it work in a clean way. I tried the -border and -extent options but they behaved sort of inconsistently, so I'm thinking about falling back to the pad filter in ffmpeg:

ffmpeg -i input.jpg -vf "pad=1500:1500:(ow-iw)/2:(oh-ih)/2:color=white" output.jpg

This is just so much more straightforward - you set the canvas size, the location, and the color, and that's it. Is there a similar solution using the ImageMagick tools?

    What have you tried with IM and how did it not work? – slhck Jun 16 '19 at 13:26

I found something that works for me:

convert input.jpg -extenet WIDTHxHEIGHT+X+Y -background COLOR output.jpg

this allows offsetting much like with the pad filter in ffmpeg. I think what confused me is that the -bordercolor option doesn't seem to work on my setup with the convert command, while it works fine with mogrify. I don't know whether I'm missing something or this is a bug.
