如何在已知名称的其他组图层中裁剪和导出特定的组图层？

Question

第一次在这里发布！如果此贴缺少信息或令人讨厌，我事先表示歉意。

所以，我有一堆层，结构有点像这样：

+ graphics (group, unique)
+ - + Figure_A (group, unique)
+ - + - + Figure_A_arm (group, unique)
+ - + - + - + Figure_A_arm_Variation1 (group, unique)
+ - + - + - + - + frame1_arm (group, not unique)
+ - + - + - + - + - + FigureGraphic (linked layer, not unique, has a mask)
+ - + - + - + - + frame2_arm (group, not unique)
+ - + - + - + - + - + FigureGraphic (linked layer, not unique, has a mask)
+ - + - + - + - + frame2_arm (group, not unique)
+ - + - + - + - + - + FigureGraphic (linked layer, not unique, has a mask)

（唯一/不唯一表示图层名称是否唯一）

我正在尝试获取组层次结构中最新的像素，并在自动导出之前裁剪文档。主要的问题是，即使不停地戳了两周，我还是不知道有很多功能。我在脚本中挖了很多代码片段，但结果变成一团糟，无法正常工作。 我要在尝试执行的操作中包含伪代码。理想情况下，我会在其中编写这些函数，但是在谷歌搜索了两个星期之后，我看不清其中的很多功能。 Photoshop脚本中的许多功能似乎相当模糊，我根本无法弄清楚它们……

我一直在通过从以下位置获取代码段来编写函数：

我一直在尝试，但是我发现很难实现它们来执行我需要的操作，有时我会遇到错误，或者变量变得“未定义”，从而引发错误。

// Here's some 'pseudocode' with how I'm trying to make it work
cropAndSave("Figure_A_arm_Variation1");
cropAndSave("Figure_A_arm_Variation2");
cropAndSave("Figure_A_arm_Variation3");
cropAndSave("Figure_A_leg_Variation1");
cropAndSave("Figure_A_leg_Variation2");
cropAndSave("Figure_A_leg_Variation3");
cropAndSave("Figure_B_arm_Variation1");
cropAndSave("Figure_B_arm_Variation2");
cropAndSave("Figure_B_arm_Variation3");
//etc

function cropAndSave(nameOfGroup)
{
    //nameOfGroup is the group layer we are looking for

    //Duplicate the document so we don't mess with the original
    var workingDoc = app.activeDocument.duplicate();

    // Path we want to export to
    var path="C:/test/"+nameOfGroup+"/";

    // Look up for this group layer in the document
    setActiveLayerSet(nameOfGroup);

    // Make a list (array?) with the ids of each layer set/group inside nameOfGroup
    // This shouldn't include anything inside each group, only the direct groups inside nameOfGroup
    var listOfLayers = getListOfChildrenObjects();

    // Loop the process for each sub-object
    for( var i = 0; i < listOfLayers.length ; i++ )
    {
        var name = getLayerNameById(listOfLayers.i); //I don't know if this is the correct way to ask for the i element of a list
        var bounds = []; //We'll be using this for the cropping
        if(groupName=="Figure_A_arm_Variation1") //Checking which set we're doing
        {
            if(name=="frame1_arm") bounds = [1px, 2px, 3px, 4px]; //just a test value
            else if(name=="frame2_arm") bounds = [5px, 6px, 7px, 8px]; //just a test value
            else if(name=="frame3_arm") bounds = [9px, 10px, 11px, 12px]; //just a test value
            else if(name=="frame1_leg") bounds = [13px, 14px, 15px, 16px]; //just a test value
            // and so on
        }
        else if(groupName=="Figure_B_arm_Variation2") //one of the many possible groups
        {
            if(name=="frame1_arm") bounds = [17px, 18px, 19px, 20px];
            //etc
        }
        // Duplicate this since we will be doing more drastic changes
        var secondaryDoc = workingDoc.duplicate();

        // Select the layer we're working with
        selectLayerByID(listOfLayers.i);

        // Do the cropping
        if(bounds.length > 2) secondaryDoc.crop(bounds); //Each bounds array has 4 elements, check if that's the case to make sure we haven't input any weird values, then crop
        else alert('No bounds set up for layer '+name+' in group '+groupName); //in this case it should be cancelled but I'm not sure how to stop the script from executing

        // Condense the group 'name', which is the one we're working with, into a single layer for easier management
        condenseGroup();

        // Remove all the layers that aren't the one we're working with
        deleteAllLayersAndGroupsExceptSelected();

        // Save as PNG
        var pngFile = new File(path+name);
        pngSaveOptions = new PNGSaveOptions();
        pngSaveOptions.embedColorProfile = true;
        pngSaveOptions.formatOptions = FormatOptions.STANDARDBASELINE;
        pngSaveOptions.matte = MatteType.NONE; pngSaveOptions.quality = 1;
        activeDocument.saveAs(pngFile, pngSaveOptions, false, Extension.LOWERCASE);

        // Close this duplicate without saving the PSD
        secondaryDoc.close(SaveOptions.DONOTSAVECHANGES);
    }
    workingDoc.close(SaveOptions.DONOTSAVECHANGES); 
}

所以我要摆脱的是，在具有特定的组结构的同时，使其在层次结构中选择一个组，然后将文档裁剪为一组后，将每个子组的内容另存为PNG。尺寸，但我很难找到正确的方法和功能。

[编辑]请求的图像发​​布在这里：

这是Layer structure。每个“ Figure_ X _ bodypart _Variation Y ”中都有一组子组。我想通过将文档裁剪为特定的边界来处理这些子组中的每个子组，这些边界已编码到每个子组的脚本中。

I have the PSD structured like this，打开的文件夹有一个遮罩（这是用于显示哪些像素属于该图层的当前选择）。我希望脚本选择为该图层指定的矩形，例如this。

之后，我希望脚本复制文档（以免与原始文档混淆），然后在脚本中为该组提供crop using the bounds。之后，脚本should remove all the other groups so only this one remains将其保存为PNG，然后关闭重复的文档，然后继续下一个子对象。

完成所有子对象后，继续每个“ Figure_ X _ bodypart _Variation Y ”类型组
