how o change background color of an image using script?

Hi @pb4891,

please explain:

- which scripting language?

- only the background color itself?

- or do you want to fill the canvas of the background layer?

- do you always have a real background layer?

But anyway - try this to change only the background color with javascript:

// create a color of your choice
var BGcolor = new SolidColor();
BGcolor.rgb.red = 0;
BGcolor.rgb.green = 0;
BGcolor.rgb.blue = 255;

// set your color as background color
backgroundColor.rgb.hexValue = BGcolor.rgb.hexValue;

And this will change the color of background layer:

// BGcolor_fillBackgroundLayer.jsx
// https://forums.adobe.com/message/7781601#7781601

// required: an opened document
// fill canvas with blue color - if background layer exists
// regards pixxxelschubser

// create a color of your choice
var BGcolor = new SolidColor();
BGcolor.rgb.red = 0;
BGcolor.rgb.green = 0;
BGcolor.rgb.blue = 255;

// set your color as background color
backgroundColor.rgb.hexValue = BGcolor.rgb.hexValue;

// check if a real background layer exists and fill with your color
var aDoc = app.activeDocument;
var theLayers = aDoc.layers;
aDoc.activeLayer = theLayers[theLayers.length-1];
var aLayer = aDoc.activeLayer;

if (aLayer.isBackgroundLayer) {
    app.activeDocument.selection.fill (backgroundColor, ColorBlendMode.NORMAL, 100, false);
    alert("Done")
    } else {
        // here you could create a new background layer - instead of the alert
        alert ("Sorry, but there is no background layer");
        }

Have fun
