I would like to make all of the pictures to aspect 1:1 by adding white background.

By adjusting each picture to it's biggest height OR width and NOT cropping or changing the size of the actual picture. The script I have does not work and errors out. I am not sure why. Can anyone help out or do you have a script that does what I am looking to do?

[CODE=javascript]// Open folder selection dialog

var inputFolder = Folder.selectDialog("Select a folder with images");

// Check if a valid folder was selected

if (inputFolder) {

    var files = inputFolder.getFiles(/\.(jpg|jpeg|png|tif|tiff|psd)$/i);

   

    for (var i = 0; i < files.length; i++) {

        var file = files[i];

        if (file instanceof File) {

            open(file);

            // Get the active document

            var doc = app.activeDocument;

            // Get original width and height

            var originalWidth = doc.width;

            var originalHeight = doc.height;

            // Determine the new canvas size (largest dimension)

            var newSize = Math.max(originalWidth, originalHeight);

            // Resize canvas to make it square (1:1 ratio)

            doc.resizeCanvas(newSize, newSize, AnchorPosition.MIDDLECENTER);

            // Deselect any active selection

            doc.selection.deselect();

            // Select the original image layer

            var imageLayer = doc.activeLayer;

            // Create a new solid white background layer

            var whiteBackground = doc.artLayers.add();

            whiteBackground.name = "White Background";

            // Fill the new layer with white

            doc.activeLayer = whiteBackground;

            var white = new SolidColor();

            white.rgb.red = 255;

            white.rgb.green = 255;

            white.rgb.blue = 255;

            doc.selection.selectAll();

            doc.selection.fill(white);

            doc.selection.deselect();

            // Move the white background layer to the **bottom**

            whiteBackground.move(doc.artLayers[doc.artLayers.length - 1], ElementPlacement.PLACEATEND);

            // Ensure the original image stays on top

            imageLayer.move(doc.artLayers[0], ElementPlacement.PLACEATBEGINNING);

            // Flatten the image to merge layers correctly

            doc.flatten();

            // Save the modified image

            var saveFile = new File(file.path + "/" + file.name);

            var saveOptions = new JPEGSaveOptions();

            saveOptions.quality = 12; // Max quality

            doc.saveAs(saveFile, saveOptions, true, Extension.LOWERCASE);

            // Close the document without saving additional changes

            doc.close(SaveOptions.DONOTSAVECHANGES);

        }

    }

   

    alert("Batch processing completed!");

} else {

    alert("No folder selected. Process canceled.");

}
