Photoshop 脚本 - 如何获取图层集（组）可见部分的边界？

Question

我正在编写一个简单的 Photoshop 脚本，我需要活动图层可见部分的边界（即应用蒙版后的边界）。

值得庆幸的是，ArtLayer.bounds 属性为您提供了任何给定层的准确信息。

但是，如果活动层实际上是一个组（层集），事情就变得复杂了。

首先，完全忽略了组的遮罩效果。其次，层的可见性状态也被忽略了。

所以我的问题是：如何获取图层集（组）可见部分的边界？

或者至少，我如何获得组蒙版的边界？如果我有，我可以遍历所有组的可见层边界并与所有相交他们中的一些人带着面具来得到我需要的东西。

我在 reference guide 中没有找到任何方法或属性可以给我其中任何一个。

如有任何帮助，我们将不胜感激！谢谢！

这是一个 hacky 解决方案，它创建组的临时副本，合并它，获取它的边界，删除它并返回到组，这将处理不可见层

var mfDoc = activeDocument;
var mflayer = activeDocument.activeLayer; // currently active layer
var mfnewdLayer = mfDoc.activeLayer.duplicate(); // Dublicates active layer or group (creating a temp layer)
mfDoc.activeLayer = mfnewdLayer; // sets the temp layer as the active layer
mfnewdLayer.merge(); // merges it, this leaves only visible layers

var mfmlayer = activeDocument.activeLayer; //Grab the currently selected layer
var mfheight = mfmlayer.bounds[2]-mfmlayer.bounds[0]; //Grab the H value
var mfwidth = mfmlayer.bounds[3]-mfmlayer.bounds[1]; //Grab the W value

mfmlayer.remove(); // delete the temp layer
mfDoc.activeLayer = mflayer; // gets back to the layer that was active at the begining
mflayer.name = mfheight + " x " + mfwidth // set it's name to the dimintions we now have

现在如果你想处理 masks 脚本会稍微长一点：

var mfDoc = activeDocument;
var mflayer = activeDocument.activeLayer; // currently active layer
var mfnewdLayer = mfDoc.activeLayer.duplicate(); // Dublicates active layer or group (creating a temp layer)
mfDoc.activeLayer = mfnewdLayer; // sets the temp layer as the active layer
mfnewdLayer.merge(); // merges it, this leaves only visible layers

var mfmlayer = activeDocument.activeLayer; //Grab the currently selected layer

        if (hasVectorMask() == true){ // Only if it has a layer mask
                selectVectorMask(); // Select the vector mask
                rasterizeVectorMask(); // rasterize the vector mask
                applyLayerMask(); // Apply the layer mask
            }
        if (hasLayerMask() == true){ // Only if it has a layer mask
                selectLayerMask(); // Select the layer mask
                applyLayerMask(); // Apply the layer mask
            }
        if (hasFilterMask() == true){ // Only if it has a Smart Filter mask
            }

var mfheight = mfmlayer.bounds[2]-mfmlayer.bounds[0]; //Grab the H value
var mfwidth = mfmlayer.bounds[3]-mfmlayer.bounds[1]; //Grab the W value

mfmlayer.remove(); // delete the temp layer
mfDoc.activeLayer = mflayer; // gets back to the layer that was active at the begining
mflayer.name = mfheight + " x " + mfwidth // set it's name to the dimintions we now have
