Hello i want to have a script takat creates bleeds,

Usually when im dong this by hand I do this:
1. create naew layer and mae it "bleed", fill it witch bucket tool

2.Expand canvas s

3.Select bleed layer with CMD, clear it, reverse the selection an fill it with color

 

But i cant figure out how to do step 3. I can ony select the whole layer and not the only filed part

 

This is my code:

 

 

var bleedLayer = app.activeDocument.artLayers.add();
bleedLayer.name = "bleed";

bleedLayer.move(app.activeDocument.artLayers[0], ElementPlacement.PLACEBEFORE);

app.activeDocument.selection.selectAll();
app.activeDocument.selection.fill(app.foregroundColor);
app.activeDocument.selection.deselect();

var doc = app.activeDocument;
var originalWidth = doc.width;
var originalHeight = doc.height;
var newWidth = originalWidth + 10;
var newHeight = originalHeight + 10;
doc.resizeCanvas(newWidth, newHeight, AnchorPosition.MIDDLECENTER);

doc.activeLayer = bleedLayer;
doc.activeLayer = doc.artLayers.getByName("bleed");
doc.selection.load(doc.activeLayer.channels["Transparency"], SelectionType.REPLACE);
doc.selection.clear();
doc.selection.invert();
doc.selection.fill(app.foregroundColor);
doc.selection.deselect();

Could you please post screenshots with the pertinent Panels (Toolbar, Layers, Options Bar, …) visible to illustrate the process? 

 

loadTransparency (false);
////// load transparency //////
function loadTransparency (theInvert) {
// =======================================================
var idsetd = charIDToTypeID( "setd" );
    var desc3 = new ActionDescriptor();
    var idnull = charIDToTypeID( "null" );
        var ref2 = new ActionReference();
        var idChnl = charIDToTypeID( "Chnl" );
        var idfsel = charIDToTypeID( "fsel" );
        ref2.putProperty( idChnl, idfsel );
    desc3.putReference( idnull, ref2 );
    var idT = charIDToTypeID( "T   " );
        var ref3 = new ActionReference();
        var idChnl = charIDToTypeID( "Chnl" );
        var idChnl = charIDToTypeID( "Chnl" );
        var idTrsp = charIDToTypeID( "Trsp" );
        ref3.putEnumerated( idChnl, idChnl, idTrsp );
    desc3.putReference( idT, ref3 );
    desc3.putBoolean(charIDToTypeID("Invr"), theInvert);
executeAction( idsetd, desc3, DialogModes.NO );
};

    Hello! Thank you very much it works witch your metchod!

    I'm coping my code here so if anyone in the future needs something similar there's an answer

    // Funkcja do ładowania przezroczystości jako zaznaczenia
function loadTransparency(theInvert) {
    var idsetd = charIDToTypeID("setd");
    var desc3 = new ActionDescriptor();
    var idnull = charIDToTypeID("null");
    var ref2 = new ActionReference();
    var idChnl = charIDToTypeID("Chnl");
    var idfsel = charIDToTypeID("fsel");
    ref2.putProperty(idChnl, idfsel);
    desc3.putReference(idnull, ref2);
    var idT = charIDToTypeID("T   ");
    var ref3 = new ActionReference();
    var idChnl = charIDToTypeID("Chnl");
    var idTrsp = charIDToTypeID("Trsp");
    ref3.putEnumerated(idChnl, idChnl, idTrsp);
    desc3.putReference(idT, ref3);
    desc3.putBoolean(charIDToTypeID("Invr"), theInvert);
    executeAction(idsetd, desc3, DialogModes.NO);
}

// Tworzenie nowej warstwy i nadanie jej nazwy "bleed"
var bleedLayer = app.activeDocument.artLayers.add();
bleedLayer.name = "bleed";

// Przeniesienie warstwy "bleed" na samą górę
bleedLayer.move(app.activeDocument.artLayers[0], ElementPlacement.PLACEBEFORE);

// Wypełnienie warstwy "bleed" za pomocą narzędzia Paint Bucket Tool
app.activeDocument.selection.selectAll();
app.activeDocument.selection.fill(app.foregroundColor);
app.activeDocument.selection.deselect();

// Powiększenie rozmiaru canvasu o 10 mm z każdej strony
var doc = app.activeDocument;
var originalWidth = doc.width;
var originalHeight = doc.height;
var newWidth = originalWidth + 10; // 10mm to pixele
var newHeight = originalHeight + 10;
doc.resizeCanvas(newWidth, newHeight, AnchorPosition.MIDDLECENTER);

// Zaznaczenie widocznych elementów na warstwie "bleed"
doc.activeLayer = bleedLayer;
loadTransparency(false); // Załaduj nieprzezroczyste piksele jako zaznaczenie

// Wyczyszczenie zaznaczonych pikseli na warstwie "bleed"
doc.selection.clear(); 

// Odwrócenie zaznaczenia, aby zaznaczyć resztę
doc.selection.invert(); 

// Wypełnienie zaznaczenia kolorem pierwszego planu
doc.selection.fill(app.foregroundColor);

// Odznaczenie zaznaczenia
doc.selection.deselect();
