Understanding the DOM

[davidn5918184]

I'm just trying to understand the DOM and I'm not sure how to do this. 

I was just trying to take a selected image and apply the effect innerGlowSettings with a grey color to it. 

I'm able to take the selection and apply most of the settings with the exception of the color. When I look at the DOM it shows a property of effectColor and the type is Swatch(how do you understand that?). The description shows I can add it multiple ways, I just want 50% grey. How do I know how to apply this property?

This was my attempt but unsuccessful. Thank you for any insight.

app.selection[0].transparencySettings.innerGlowSettings.applied = true;
app.selection[0].transparencySettings.innerGlowSettings.opacity = 100;
app.selection[0].transparencySettings.innerGlowSettings.spread = 0;
app.selection[0].transparencySettings.innerGlowSettings.source = (InnerGlowSource.CENTER_SOURCED);
app.selection[0].transparencySettings.innerGlowSettings.blendMode = (BlendMode.NORMAL);
app.selection[0].transparencySettings.innerGlowSettings.opacity = 100;
app.selection[0].transparencySettings.innerGlowSettings.spread = 0;
app.selection[0].transparencySettings.innerGlowSettings.size = 0;
app.selection[0].transparencySettings.innerGlowSettings.effectColor = (Swatch = [0,0,0,40]);

and now I see I can combine them, and I can use the black swatch but I don't know how to build it in CMYK. Mostly I'm interested in how by looking a the DOM I would know how to do it as CMYK.

app.selection[0].transparencySettings.innerGlowSettings.properties = {

    applied: true,
    opacity: 100,
    spread: 0,
    source: (InnerGlowSource.CENTER_SOURCED),
    blendMode: (BlendMode.NORMAL),
    opacity: 100,
    spread : 0,
    size : 0,
    effectColor: "Black"
};

Hi @davidn5918184,

The DOM documentation seems to be misleading, I was not able to get it work with an array argument as well. However, you can do it by first adding your color if it's not already added and then using it. Try the following

var col = app.documents[0].colors.itemByName("My Gray")
if(!col.isValid)
	col = app.documents[0].colors.add({colorValue:[0,0,0,40], name:"My Gray", space:ColorSpace.CMYK})
	
app.selection[0].transparencySettings.innerGlowSettings.properties = {

    applied: true,
    opacity: 100,
    spread: 0,
    source: (InnerGlowSource.CENTER_SOURCED),
    blendMode: (BlendMode.NORMAL),
    opacity: 100,
    spread : 0,
    size : 0,
    effectColor: col
};

This works. I'm really trying to figure out how to understand the DOM and script using it but it is so confusing. Thanks for the help.
