Resize a layer

[Ciccillotto]

I want to resize a layer to this size 6000x4000
But I didn't find anything in uxp
Does anyone have a piece of code I can use.

[c.pfaffenbichler]

Are you deliberately avoiding ESTK-code? 

[Ciccillotto]

If I can do it in uxp it's better
Alternatively I try with estk.

Layer bounds is still a thing in UXP, so I'd start there:

https://developer.adobe.com/photoshop/uxp/2022/ps_reference/objects/bounds/

I'll take a look when I have some free time.

Converting the layer to a smart object and editing the content and using image size to a specific px target is also possible for batchPlay UXP, but has more overhead.

This BatchPlay code was generated with the help of AI (the generated DOM code was useless). Adjust the interpolationType as required:

const app = require('photoshop').app;
const batchPlay = require('photoshop').action.batchPlay;

resizeLayer();

async function resizeLayer() {
    const command = {
        _obj: "transform",
        width: {
            _unit: "pixelsUnit",
            _value: 6000
        },
        height: {
            _unit: "pixelsUnit",
            _value: 4000
        },
        linked: false,
        interfaceIconFrameDimmed: {
            _enum: "interpolationType",
            _value: "bilinear"
        },
    };

    try {
        await batchPlay([command], {});
        console.log("Resize completed!");
    } catch (err) {
        console.error(err);
    }
}

I used the convert to smart object method

Curious! Obviously performance and workflow aren't an issue.

1. Convert to SO
2. Edit the SO
3. Image Size
4. Close/Save the SO
5. Optionally convert the SO back to a layer or rasterize

Stefano I used the convert to smart object method just because it was easier at the moment, The uxp code you put doesn't work and finding the problem would have cost me time, which I don't have at the moment. Maybe if I free myself up a bit I'll see if I can make it work.

Ah OK, the .psjs file obviously worked for me (Ps 2024).

[Ciccillotto]

I hadn't thought about psjs, I'll try it later, if it goes well I'll use this method. Thanks for your help.

[Ciccillotto]

Stefano I tried with psjs and it works fine
thanks a lot for your help

You're welcome! It always resizes from the default middle-centre. I couldn't work out how to change the resize anchor point.

[Ciccillotto]

I also had this problem
I solved it using center vertical level and center horizontal

kindly tell me with which AI you created the script above.

[Stephen Marsh]

Yes, post transformation alignment or X/Y translation.

As for AI, I tried "the big 3" - ChatGPT, Claude and CoPilot (surprisingly, Gemini is almost useless for Photoshop scripting).

I tried many iterations of UXP DOM code before giving up and asking it to use BatchPlay instead. 

I can't remember which of the 3 provided the final working code, or perhaps it was a combination - feeding the output of one as the input to another.
