How to make square that fills with border?

I can scale the photo, or add a border to it.
But how could I make the photo to the square that fills with the border?

Hello @filmape,

I’m not quite following what you’re asking for. Can you point to an example that I can see?

I want to add border to make non square photo to square that I can post to instagram. like the border does in VSCO app

So you’re basically wanting to crop the image, and then apply a border to it? You can do that today with the Crop node, and by choosing the type to “Aspect ratio”, and then ratio to 1x1 (square). Does that work for you?
