Hi All,

I am new to scripting and I am trying to get the logic to change the opacity of a layer. Here's what I have so far.

//This is just a test script
#target photoshop

//bring application forward for double-click event
app.bringToFront();

//ensure that at least one document is open
if (!documents.length){
    alert ('There are no documents open');

//if no document is open it will automatically create a new document once the user clicks ok
app.preferences.rulerUnits = Units.PIXELS
var docCount=documents.length
if (docCount==00
documents.add(1920,1080)

//create a new art layer at the beginning of the current document
var layerRef = app.activeDocument.artLayers.add()
layerRef.name = "Background"
layerRef.blendMode = BlendMode.NORMAL

//Select all so we can apply a fill to the selection
app.activeDocument.selection.selectAll

//create a color to used with the fill command
var colorRef = new SolidColor
colorRef.rgb.red = 0
colorRef.rgb.green = 0
colorRef.rgb.blue = 0

//Now apply fill to current selection
app.activeDocument.selection.fill(colorRef)
function changeOpacity(Background,opacity){
     var object = imageObject.Style
     object.opacity = (opacity/50);
     object.filter = "alpha (opacity = " + opacity + + "(";

I know this is simple but I can't seem to figure it out.

Thank You!

Something like this...


 
//This is just a test script  

#target photoshop  

 

//bring application forward for double-click event  

app.bringToFront();  

var current_units = preferences.rulerUnits;  

app.preferences.rulerUnits = Units.PIXELS  

 

documents.add(1920,1080)  

//create a new art layer at the beginning of the current document  

var layerRef = app.activeDocument.artLayers.add()  

layerRef.name = "Background2"  

layerRef.blendMode = BlendMode.NORMAL  

//Set opacity of new layer 

layerRef.opacity=60; 

//Select all so we can apply a fill to the selection  

app.activeDocument.selection.selectAll  

 

//create a color to used with the fill command  

var colorRef = new SolidColor  

colorRef.rgb.red = 0  

colorRef.rgb.green = 0  

colorRef.rgb.blue = 0  

 

//Now apply fill to current selection  

app.activeDocument.selection.fill(colorRef); 

app.activeDocument.selection.deselect(); 

preferences.rulerUnits = current_units;
