Opacity

[_Kin2001_]

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;

I wonder if there's an option that if there's no Document, it will just stop running the script.

Something like:

if (!documents.length) {

     alerts ("There are no Documents");

     Exit (); // A function that stops the script

}

Has anyone succeeded doing it?

Thanks.

function main()  {
  if (app.documents.length == 0) {
     return;
  }
  var doc = app.activeDocument;
  // insert code here
};
main()
