SCALE ARTBOARD AND CONTENT

As mentioned, here is a first draft of a new script for resizing artboards. It uses a different method than my previous script, using a script interface rather than an interactive free transform:

Currently, it is only for use with a single artboard selected at a time.

It has not had exhaustive testing on complex artboards. Work on duplicates of any important files for safety. As resizing artboards requires canvas resizing, the script uses the Trim command to force trim to transparency, and may also benefit with saving before or after resizing an artboard to force the "shrinkwrap on save" to kick in, as the next artboard resize may not work correctly. Your insights from testing may be invaluable for getting this to work. I don't use artboards very often and I hate scripting them.

Use with caution!

Baby steps, once It is working for one artboard, the script can then be modified to cycle over all artboards.

P.S. Why not keep each artboard at 3000 px and resize the output to 2000 px when using Export As?

OK. I wish this was already part of PSD as I have several PSB files with each 30 artboards that need resizing from 3000x to 2000x scaled content... lot's of work and I don't have any coding skills

@Todd_Morgan 

I'll test for that, the script was only ever intended for use on a single artboard at one time.

I'm working on a new version that handles content outside of the artboard, again this is only intended for one artboard at a time.

OK so the script works if I have one artboard open and all layers selected... but if I have several artboards selected (layers are twirled closed) then I get that error...

still getting error - I am using the latest version of PSD

@Todd_Morgan 

I just tested in Photoshop 2021 and 2024 and the script works as expected without error.

Looking at line 88, I'm not sure why you would get that error.

What version are you using?

You could try changing line 88 from:

var tempGroup = sourceGroup.layerSets.add();

To this:

var tempGroup = app.activeDocument.activeLayer.layerSets.add();

 i get this when running script

yes you understood me completly, unfortently i usually have extended content in my artboards

but i love that someone trying to do this kind of script and i hope adobe will notice and know that creating auto adjustment for artboards is a must since i think alot of people need to create banners in a lot of different sizes and auto layout/sizing is importnat for this kind of work.

so again thank u

thanks for that, i tried using it and set the free transform to scle 30% and it did scale all the layers but it didnt scale the artboard, it actully made it larger than before, since the backgroung layer it much larger than the artboard.

By @Lital5E82 

Thank you for the feedback!

In my tests, having a true Background layer shouldn't matter, as the artboard size and content is what is being resized.

So do you mean that you have content in the artboard that extends beyond the visible bounds of the artboard? That would be problematic for resizing with the current coding, as that wasn't expected/taken into account.

I have updated the notes to include this limitation. At the moment I can't think of an easy work-around without a major rewrite of the code.
