How to get layer blendRange property?

Photoshop UXP Plugin API
,
1

With Alchemist I found how to set blendRange, but I can’t figure out how to get it. Tried variations of such descriptor:

{
    "_obj": "get",
    "_target": [
        { "_property": "blendRange" },
        {
            "_ref": "channel",
            "_enum": "channel",
            "_value": "gray"
        },
        {
            "_ref": "layer",
            "_enum": "ordinal",
            "_value": "targetEnum"
        }
    ]
}

Also just for layer:

{
    "_obj": "get",
    "_target": [
        { "_property": "blendRange" },
        {
            "_ref": "layer",
            "_enum": "ordinal",
            "_value": "targetEnum"
        }
    ]
}

And just for channel:

{
    "_obj": "get",
    "_target": [
        { "_property": "blendRange" },
        {
            "_ref": "layer",
            "_enum": "ordinal",
            "_value": "targetEnum"
        }
    ]
}

None worked. Error:

The command “Get” is not currently available.

Any way to get Blend if... data?

is this a property you want to get ?

Yes :slightly_smiling_face: After I got to bed yesterday, I remembered about this JSON property too. Will test a bit later today and let you know :pray:

Nope, desn’t really work :frowning: If there are layers in a group and you want to get any of those, it always returns the parent (group) layer data :confused:

My structure:

- Layer
- Group
|- GroupLayer1
|- GroupLayer2
'- GroupLayer3

If I select Group, it returns data for Group, but…

  • If I select Layer, it returns data for both Layer and Group
  • If I select any of the GroupLayerX, it returns data always just for Group

It doesn’t matter if I try to get data by active layers or by passing _index or _id

5

I guess I can get the data from the document json property, but I’ll have to search recursively through a layer tree to find the layers I need…

6

No need to search. In JSON property descriptor you can pick the layerID you want to. So you will get only one layer.

7

What do you mean? At least what I’ve tried, didn’t work. It always returns group layer:

It doesn’t matter if I try to get data by active layers or by passing _index or _id

8

It does not use the reference. This is the same: Photoshop Kevlar API Additions for Generator · adobe-photoshop/generator-core Wiki · GitHub

OK, I really tried understanding that piece of code, but I guess without ActionScript knowledge it’s a bit too much. I still have no idea how to request specific layer JSON in UXP :confused:

10

You can check Alchemist… it generates template code for you:

Or json property of layer directly

Yes, so that’s what I did as you suggest in the first option, to get document json, but then I need to parse all layers tree.

The second option to get by layer ID directly - I tried, and as I mentioned, it doesn’t really work. Responses don’t make much sense to me if I’m honest. For example this:
