How do you access layer style information in Photoshop?

I'm doing some research before I write a script for Photoshop CS3. I want to write the script in Photoshop with JavaScript.

I have looked through the Photoshop JavaScript Guide, but I can't find any way to get layer style information for a layer (stroke, gradient, outer glow, etc).

There is a way to set layer styles, but I haven't been able to find anything that lets you get the information.

I only have Photoshop CS3, so I'm looking for a solution that will s开发者_StackOverflow社区uit that.

Open the Adobe ExtendScript Toolkit. In the menu go to Help > Object-Model Viewer (or similar, mine is in german).

Inside the Object-Model browser in the "Browser" side-tab select Photoshop. Now you can search with the search field on the top right corner.

See the image below for ArtLayer's deifinition and ArtLayer.applyStyle():

Search around, it's much better than adobe's documentation.

I hope I am not too late, I reat your post, because I had the same problem and I found a solution on http://www.rags-int-inc.com/PhotoTechStuff/CollageTemplate/index.html. This guy has a script called "Layer Effects Options". You can download the source at the bottom.

Well it's only a panel to apply Effects, but if you browse through the code you can extract what you need.

Here is a little exsample (what I needed) for applying an stroke effect an the active layer

function newStrokeEffect(strokeSize, strokeColor, strokePosition) {
    var effectDescriptor = new ActionDescriptor();
    var effectColor = new ActionDescriptor();
    var strokeOpacity = 100.0;      // 0 - 100 %
    var strokeBlend = "Nrml";       // Normal[Nrml], ColorBurn[CBrn], SoftLight[SftL}, Color[Clr ]

    effectDescriptor.putBoolean(charIDToTypeID("enab"), true);
    effectDescriptor.putEnumerated(charIDToTypeID("Styl"), charIDToTypeID("FStl"), charIDToTypeID(strokePosition));
    effectDescriptor.putEnumerated(charIDToTypeID("PntT"), charIDToTypeID("FrFl"), charIDToTypeID("SClr"));
    effectDescriptor.putEnumerated(charIDToTypeID("Md  "), charIDToTypeID("BlnM"), charIDToTypeID(strokeBlend));
    effectDescriptor.putUnitDouble(charIDToTypeID("Opct"), charIDToTypeID("#Prc"), strokeOpacity);
    effectDescriptor.putUnitDouble(charIDToTypeID("Sz  "), charIDToTypeID("#Pxl"), strokeSize);
    effectColor.putDouble(charIDToTypeID("Rd  "), strokeColor.rgb.red);
    effectColor.putDouble(charIDToTypeID("Grn "), strokeColor.rgb.green);
    effectColor.putDouble(charIDToTypeID("Bl  "), strokeColor.rgb.blue);
    effectDescriptor.putObject(charIDToTypeID("Clr "), charIDToTypeID("RGBC"), effectColor);
    return(effectDescriptor);
}

var tmpC = new SolidColor();
tmpC.rgb.hexValue = "FF00FF";
var layerOptions = new ActionDescriptor();
var refr01 = new ActionReference();
var layerProperties = new ActionDescriptor();

layerOptions.putUnitDouble(charIDToTypeID("Scl "), charIDToTypeID("#Prc"), 400.0);

var layerEffects = newStrokeEffect(2, tmpC, "InsF");

layerOptions.putObject(charIDToTypeID("FrFX"), charIDToTypeID("FrFX"), layerEffects);

refr01.putProperty(charIDToTypeID("Prpr"), charIDToTypeID("Lefx"));
refr01.putEnumerated(charIDToTypeID("Lyr "), charIDToTypeID("Ordn"), charIDToTypeID("Trgt"));
layerProperties.putReference(charIDToTypeID("null"), refr01);
layerProperties.putObject(charIDToTypeID("T   "), charIDToTypeID("Lefx"), layerOptions);

try {
    executeAction(charIDToTypeID("setd"), layerProperties, DialogModes.NO);
} catch(ex) {
    if (ex != "Error: User cancelled the operation")
        alert(scriptName + " newLayerEffect() exception caught? line[" + ex.line + "] "  + ex);
}

I did not know the exact meaning of all lines (it is mainly copy & paste), but it works :-) (only tested it on Photoshop CS5)

A new module jamStyles has been recently added to the JSON Action Manager scripting library for Photoshop.

Among other stuff, it defines two JavaScript functions jamStyles.getLayerStyle and jamStyles.setLayerStyle which provide support for getting and setting the current layer style (both blending options and layer effects) using a JSON object.

A utility script called Get Layer Style is also provided.
