P: Export As now crops to contents instead of using the mask

And another thing. This article explains You could alter the canvas size while exporting to have some control on the output size: https://helpx.adobe.com/photoshop/using/export-artboards-layers.html

But when I try this with an image inside an art board (so not just the canvas), the export window crashes.

Still no fix for this, Adobe? This really messes with our workflow here. We have to be able to export multiple Layer(folders) to PNG files while keeping control over the file size (in pixels) of those exports. That was possible by applying a mask to those layers to determine the size. 

We can not use the size of the canvas or art boards as suggested because the exports all need to have different sizes. Creating an artboard for each individual image would be crazy.

Please fix this.

I certainly hope a solution is in the works.   My needs are the same as yours.

Is a permanent solution for this problem still in the works? We are exporting assets for games, and it's really important to have control over how a layer is placed within the canvas in that case. The assets are often not centered. The legacy export options work, but a proper solution would be much better of course.

Update: Other scripted options here –

@julieb28824091 – Unfortunately, there is no legacy Export As option for M1 Macs. You can use Rosetta or one of the other workarounds mentioned in this topic.

This version works with selected layers:

Hey, @julieb28824091 

I can only offer a "work around". 

Go to programs, right click Photoshop and in the "information" menu – select open with Rosetta.  

That way it behaves like it used to for me. But it is also slower this way and there's a bug in this mode, where PS might crash if you try to move a shape's point and transform the shape into a regular path. (Can happen, but doesn't always.)
