使用Photoshop脚本更改选定文本图层的语言

Question

虽然我已经成功地编写了一个功能脚本来更改选择层的词典语言，但它还不完全符合我的需求。

目前我正在检索所选层的索引，使用它们获取层名称——这是问题所在——然后根据自定义对话框中选择的选项来更改它们的语言。

使用层名称是一种非常笨拙的解决方案，我需要精度，我需要能够根据层ID或索引来更改语言。我的脚本不仅容易出现名称冲突，而且我也不知道选择的层将在哪里，是在文档的根部还是在5个层组堆栈中。

以下是我的当前代码：

主函数

function main() {
    // Create window with language selection and retrieve selected value
    var lang = createWindow();

   // Retrieve selected layers
   var selectedLayers = getSelectedLayersIdx();

   // Look at each entry and change language when possible
   for(var a in selectedLayers){
        try {
           setLangByIndex(Number( selectedLayers[a]), lang );
        } catch(err) {   }
   }
}

(createWindow返回一个lang值，跳过该内容)

function  getSelectedLayersIdx(){
    var selectedLayers = new Array;
    var ref = new ActionReference();
    ref.putEnumerated( charIDToTypeID('Dcmn'), charIDToTypeID('Ordn'), charIDToTypeID('Trgt') );
    var desc = executeActionGet(ref);
    if( desc.hasKey( stringIDToTypeID( 'targetLayers' ) ) ) {
        desc = desc.getList( stringIDToTypeID( 'targetLayers' ));
        var c = desc.count
        var selectedLayers = new Array();
        for(var i=0;i<c;i++) {
            try{
                activeDocument.backgroundLayer;
                selectedLayers.push(  desc.getReference( i ).getIndex() );
            } catch(e) {
                selectedLayers.push(  desc.getReference( i ).getIndex()+1 );
            }
        }
    } else {
        var ref = new ActionReference();
        ref.putProperty( charIDToTypeID('Prpr') , charIDToTypeID( 'ItmI' ));
        ref.putEnumerated( charIDToTypeID('Lyr '), charIDToTypeID('Ordn'), charIDToTypeID('Trgt') );
        try {
            activeDocument.backgroundLayer;
            selectedLayers.push( executeActionGet(ref).getInteger(charIDToTypeID( 'ItmI' ))-1);
        } catch(e) {
            selectedLayers.push( executeActionGet(ref).getInteger(charIDToTypeID( 'ItmI' )));
        }
    }
    return selectedLayers;
}

设置语言的功能

function setLangByIndex(idx, lang){
    ref = new ActionReference();
    ref.putProperty( charIDToTypeID("Prpr") , charIDToTypeID( "Nm  " ));
    ref.putIndex( charIDToTypeID( "Lyr " ), idx );
    var name = executeActionGet(ref).getString(charIDToTypeID( "Nm  " ));

    var el = activeDocument.layers.getByName( name );
    // Temp quick block; MUST UPDATE IN CASE OF NEW LANGUAGES
     if (lang == 'pt_br' )
        el.textItem.language = Language.BRAZILLIANPORTUGUESE;
    else if (lang == 'en_us' )
        el.textItem.language = Language.ENGLISHUSA;
    else
        el.textItem.language = Language.ENGLISHUK;
}

我尝试的低效解决方法：

• 使用Adobe的脚本监听器和executeAction来更改语言，但无法使其正常工作。语言部分位于 ~4 个堆叠描述符（和一个列表！）中。我迷失了方向并不断出现错误8800。
• 试图通过使用 idx 来获取对象引用。失败了。

没有一个示例PSD文件，调试起来有点困难。你能否上传一个非常简化的PhotoShop文档？如果你要上传，也可以同时上传这些脚本吗？ - Tahir Ahmed

我今天早上又尝试了一次，成功了！我使用的 Script Listener 输出在这里可以找到：http://pastebin.com/U9fQKLvG这是我的当前脚本：http://pastebin.com/kZf8aeDY 我暂时不会将其发布为答案，只是想看看是否有更好的建议（我的编码能力很差！）。我使用完整的 set 操作，因为 Override 不接受 idx。PSD 示例（我认为不再需要，但…）：http://goo.gl/C9SdNu 值得注意的是，我将在不同文件上使用此脚本，因此脚本不应仅针对此示例进行调整。 - Rhaenys

在我注意到一些与段落样式相关的烦人故障后（这些故障是您可以在PS上定义为文本默认值的样式，而不是JS对象），我放弃了固执的想法，停止避免通过索引数组进行新循环以在完成后重新选择图层。
