比较 JPG 文件与 Photoshop 图层

Question

是否可以比较作为 Photoshop 图层导入的一组文件的文件名？我有一个包含 50 张 jpg 图像的文件夹，我在 PSD 文件中使用了这些图像。现在我想检查是否所有的 JPG 文件都被使用了？可以这样做吗？

Answer 1

在Javascript中，可以使用PSD.js库

Answer 2

正如我所说，Photoshop 脚本可以帮助您通过使用文件对象和基本 javascript 知识来实现这一点。我已经按照您的需要修改了我的旧脚本，现在它应该可以很好地处理任何嵌套组和图像。

我强烈建议您学习脚本编写，并在您感到困惑时在这里提问。

将下面的代码保存为 'Script.jsx' 和运行来自 'File > Scripts > Browse'

更新 2：现在它也会根据您的要求保存 log.txt 文件。 P.S。从此脚本中学习并将其调整为您想要的结果。

// Managing Document
var docs = app.documents;

// Progress Bar
var win = new Window("window{text:'Progress',bounds:[100,100,400,150],bar:Progressbar{bounds:[20,20,280,31] , value:0,maxvalue:100}};");

// assigning activeDocument
if (docs.length != 0) {
    var docRef = app.activeDocument;

    // Defining the folder
    alert("You will be prompted for the folder containing your images.\n" +
        "Files will be selected with a '.png'/'.jpg/.jpeg' on the end in the same folder.");
    var folder = Folder.selectDialog();
    if (!folder) {
        exit;
    }

    var photoFiles = folder.getFiles(/\.(jpg|jpeg|png)$/i);
    var matchFiles = [];
    var photoFilesName = [];
    //Searching for used images
    var increment = parseFloat(0);
    var divider = parseFloat(100/photoFiles.length);
    win.show();
    for (var i = 0; i < photoFiles.length; i++) {
        increment = increment + divider;
        var indexPhotoName = removeExtension(photoFiles[i].displayName);
        photoFilesName.push(indexPhotoName);
        var doc = activeDocument;
        var curLayer;
        goThroughLayers(doc, indexPhotoName);
    }

    function goThroughLayers(parentLayer, targetName) {
        for (var i = 0; i < parentLayer.layers.length; i++) {
            curLayer = parentLayer.layers[i];
            doc.activeLayer = curLayer;
            if (curLayer.typename == 'LayerSet') {
                goThroughLayers(curLayer, targetName)
            } else {
                if (curLayer.name == targetName) {
                    // if (curLayer.name.match(/[e]/ig)) {
                        matchFiles.push(targetName);
                    // }
