javascript - 使用 photoshop 脚本更改选定的文本图层语言

Question

虽然我设法放置了一个功能脚本来一起更改所选图层的字典语言，但这还不是我所需要的。

我目前正在检索我选择的图层的索引，使用它们来获取图层名称——这是有问题的部分——然后​​根据在我显示的自定义对话框。

层名称的使用是一个非常不成熟的解决方案，我需要精确度，我需要能够根据层 ID 或索引更改语言。不仅我的脚本容易出现名称冲突，而且我不知道那些选定的层将位于文档的根目录还是在 5 个组堆栈中。

这是我当前的代码:

主要功能

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，跳过那个)

迈克得到 Idx

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;
}

设置语言的函数

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;
}

我尝试过的低效解决方法:

• 使用 Adob​​e 的脚本监听器通过 executeAction 更改语言，但无法让它发挥作用。语言部分在里面~4叠描述符(和一个列表!)。我迷路了，一直收到错误 8800。
• 弄清楚如何使用 idx 获取对象引用。失败的悲惨地。

Answer 1

在我注意到一些与段落样式相关的恼人故障(您可以将其定义为 PS 上的文本的默认样式，而不是 JS 对象)之后，我放弃了顽固并停止避免通过索引数组进行新循环完成后重新选择图层。
