Question

我正在尝试找出如何在photoshop中使用javascript，但是即使我在代码中找不到逻辑错误，也无法正常工作。

我有1000多个具有不同尺寸的images / .ai文件的文件夹。我需要在枕头上保存这些图像并另存为.jpeg。我选择智能图层并运行脚本以选择图像，然后正确保存它们。唯一的问题是图像的大小调整和定位无法正常工作。如果我手动放置图像，则可以正常使用，但不能与脚本一起使用。

如果宽度大于高度，则应将宽度设置为1200 px，并据此计算高度。（反之亦然）并放置在图层的中间。

如何调整大小和位置？
是否可以选择其中包含图像的文件夹而不是选择图像？
当要在模型中更改2个智能层而不是1个时，如何处理？

任何人都知道问题出在哪里吗？非常感谢您的帮助！

我已附上2张图片。 1它看起来像什么，2脚本输出什么 Correct Wrong

替换后的图像必须与智能对象具有相同的分辨率。
您可以在代码中声明文件夹路径。如果仍要手动选择路径，则可以在路径中选择一张图像，然后提取父文件夹路径。
您可以递归浏览文档中的所有层，并提取所有要替换的智能对象。

您可能希望函数以递归方式遍历文档中的所有图层

function browseLayer(layer, fn) {
    if (layer.length) {
        for (var i = 0; i < layer.length; ++i) {
            browseLayer(layer[i], fn)
        }
        return;
    }

    if (layer.layers) {
        for (var j = 0; j < layer.layers.length; ++j) {
            browseLayer(layer.layers[j], fn);
        }
        return;
    }
    //apply this function for every layer
    fn(layer)
}

获取文档中的所有智能对象

const smartObjects = [];
//The smart objects can be visit twice or more
//use this object to mark the visiting status
const docNameIndex = {};

const doc = app.open(new File("/path/to/psd/file"));

browseLayer(doc.layers, function (layer) {
    //You cannot replace smart object with position is locked
    if (layer.kind == LayerKind.SMARTOBJECT && layer.positionLocked == false) {

        smartLayers.push(layer);

        doc.activeLayer = layer;

        //open the smart object
        executeAction(stringIDToTypeID("placedLayerEditContents"), new ActionDescriptor(), DialogModes.NO);

        //activeDocument is now the smart object
        const docName = app.activeDocument.name;

        if (!docNameIndex[docName]) {

            docNameIndex[docName] = true;

            smartObjects.push({
                id: layer.id,
                name: layer.name,
                docName: docName,
                width : app.activeDocument.width.as('pixels'),
                height : app.activeDocument.height.as('pixels'),
                resolution : app.activeDocument.resolution //important
            });
        }
        //reactive the main document
        app.activeDocument = doc;
    }

});

我假设您需要替换两个智能对象，用于替换的图像以相同的名称存储在不同的文件夹中。

smartObjects[0].replaceFolderPath = "/path/to/folder/1";
smartObjects[1].replaceFolderPath = "/path/to/folder/2";
//we need temp folder to store the resize images
smartObjects[0].tempFolderPath = "/path/to/temp/folder/1";
smartObjects[1].tempFolderPath = "/path/to/temp/folder/2";

Ex：第一次迭代会将smartObjects[0]替换为"/path/to/folder/1/image1.jpg"，并将smartObjects[1]替换为"/path/to/folder/image1.jpg"

现在按照智能对象的属性调整所有图像的大小

smartObjects.forEach(function(smartObject){

    //Get all files in the folder
    var files = new Folder(smartObject.replaceFolderPath).getFiles();

    //Resize all the image files
    files.forEach(function (file) {

        var doc = app.open(file);

        doc.resizeImage(
            new UnitValue(smartObject.width + ' pixels'),
            new UnitValue(smartObject.height + ' pixels'),
            smartObject.resolution
        );

        //save to temp folder
        doc.saveAs(
            new File(smartObject.tempFolderPath + "/" + file.name),
            new PNGSaveOptions(),
            true
        );

        doc.close(SaveOptions.DONOTSAVECHANGES)
    });

});

最后，替换智能对象

//get list of file again
var files = new Folder(smartObject.replaceFolderPath).getFiles();

files.forEach(function(file){

    var fileName = file.name;

    smartObjects.forEach(function(smartObject){

        //active the window opening the smart object
        app.activeDocument = app.documents.getByName(args.documentName);

        var desc = new ActionDescriptor();
        desc.putPath(charIDToTypeID("null"), new File(smartObject.tempFolderPath + "/" + fileName));

        executeAction(stringIDToTypeID( "placedLayerReplaceContents" ), desc, DialogModes.NO);

    });

    //Now export document
    var webOptions = new ExportOptionsSaveForWeb();
    webOptions.format = SaveDocumentType.PNG; // SaveDocumentType.JPEG
    webOptions.optimized = true;
    webOptions.quality = 100;

    doc.exportDocument(new File("/path/to/result/folder" + file.name), ExportType.SAVEFORWEB, webOptions);

});

现在您可以关闭所有打开的智能对象

smartObjects.forEach(function (s) {
    app.documents.getByName(r.docName).close(SaveOptions.DONOTSAVECHANGES);
});
