Center image inside another

[elbitjusticiero]

Hi all! I'm trying to build a workflow to adapt vertical images to a horizontal layout by superimposing the original image to a stretched and blurred version of itself, as you often see on YouTube and elsewhere.

The step I'm stuck at is having the images align in the Composite transformation. There is no option to auto-center that I can see. And I'd like this process to be scriptable, so manually aligning the image is not an option because different images will have different dimensions.

This is the script I generated with the steps I followed until this point:

Code: Select all

end_image

end 2 1 18

I thought I could use the "Size to fit" transformation to bring the original image to the same size of the boundary I need, but with a transparent background. But I don't see a way to specify a transparent background so it seems it wont' work.

Any ideas will be appreciated. Thanks in advance!

If the vertical images are all the same proportions, I think the Layout transformation will do this.

They aren't. But I think I managed to do it with Layout!

Thank you so much! I'll test what I have and let you know if I run into any problems.

It works perfectly. I've tested it with several images and so far it's been flawless. Also, very quick when run from the command line!

This is the script I'm using to do what I want:
