"Trim" in Affinity Photo

[ghobbit]

I’d like to request a Trim feature in Affinity Photo, similar to the one in Photoshop. This feature in photoshop allows users to trim or crop the canvas size to the visible pixels on screen. For example, if a layer is masked, the canvas could be cropped to fit the visible pixels of that mask.

This function is particularly useful during the macro creation process -- and is the main reason I need it. It enables users to perform batch operations on multiple images—say, 30 or 40—where a subject is selected and masked, and then "trimmed" or cropped to the mask. But most importantly, it keeps the mask intact without rasterizing or losing any data.

While "Rasterize and Trim" combined with "Clip Canvas" gets close, it results in the loss of image data that I’d like to retain for potential mask adjustments for when the select subject misses. I’ve explored various options within the macro editor but haven’t found a solution.

If there’s a current way to achieve this, please let me know. Otherwise, please consider adding this Trim feature!

Unfortunately, you can't automate that in a macro tool unless I'm wrong?

You can still do the above ("Rasterize and Trim" combined with "Clip Canvas") as when the batch file runs it creates an APhoto file for each image and APhoto automatically creates a snapshot of the image before the macro runs

So, if "Select Subject" fails for some images you can just restore the snapshot (the initial image) and redo/tweak "Select Same" as required

Not a bad solution, but still a full reset. It would work, but still not as clean as a simple Clip Canvas to mask function/Trim would be

I got fed up trying to get this to work. I don't have time to mess about so just used Krita. Easy. As. Pie.
