Automation - extending of canvas/arbeitsfläche according to x or y of resolution

Hi Team,

I use Photoshop actually to uncrop images to match their x or y resolution. I want to have quadratic images and for this use case is content aware and generative fill perfect.

Unfortunately, there is no real function in Photoshop to automate the canvas extension for this task. There is a workaround, but it works sometime and sometime not.

If there were some kind of option to extend the canvas to x or y of image resolution, I would save a lot of time, due to the possibility of automation of the process.

There s a workaround, but this process takes time (select, clone image, rotate and so on). I think if it is coded it can be really fast - extend canvas to longest side of image or so.

Or is there already such a feature and I didn't saw it?

Thank you!
