如何 - Photoshop 脚本 - 合并两个图层

Question

My Photoshop Canvas 是 900X600。

下面的函数采用 X 层并制作X 层副本。

它需要Layer X 副本，并在保持比例的同时将高度调整为 600px。var newdLayer

它采用X 层，并在保持比例的同时将宽度调整为 900px 并应用高斯模糊。var blur.

然后我想合并 X层副本和X 层。

显然有一个merge()功能，但为此你必须装箱layerset.不是真正的JavaScript专家。

如何合并两层？

(function (){
var docRef = activeDocument
var newdLayer = docRef.activeLayer.duplicate();
newdLayer;
var startRulerUnits = app.preferences.rulerUnits;  
app.preferences.rulerUnits = Units.PIXELS;  
var bounds = newdLayer.bounds;  
var height = bounds[3].value - bounds[1].value;
var newSize = (100 / height) * 600;  
newdLayer.resize(newSize, newSize, AnchorPosition.MIDDLECENTER);
app.preferences.rulerUnits = startRulerUnits;  
var blur = docRef.activeLayer;
var startRulerUnits = app.preferences.rulerUnits;  
app.preferences.rulerUnits = Units.PIXELS;  
var bounds = blur.bounds;  
var width = bounds[2].value - bounds[0].value;
var newSize = (100 / width) * 900;  
blur.resize(newSize, newSize, AnchorPosition.MIDDLECENTER);
app.preferences.rulerUnits = startRulerUnits;  
blur.applyGaussianBlur(5)
blur;
})();

我通过消除一些多余的步骤来修改您的函数，并在末尾添加了一个片段，该片段有助于创建新layerSet，将newdLayer和blur层移动到集合中，并合并该集合：

(function (){
var docRef = activeDocument
var blur = docRef.activeLayer;
var newdLayer = blur.duplicate();
var startRulerUnits = app.preferences.rulerUnits;
app.preferences.rulerUnits = Units.PIXELS;
// since we resize based on the initial size of the source layer, 
// we don't need to get the bounds twice
var bounds = blur.bounds;
var height = bounds[3].value - bounds[1].value;
var width = bounds[2].value - bounds[0].value;
// declare 2 different vars for your sizes (there are better ways to do this, but
// since you say you aren't a JavaScript pro, I figured I'd keep it simple)
var newSize600 = (100 / height) * 600;
var newSize900 = (100 / width) * 900;
// resize your layers
newdLayer.resize(newSize600, newSize600, AnchorPosition.MIDDLECENTER);
blur.resize(newSize900, newSize900, AnchorPosition.MIDDLECENTER);
// apply blur
blur.applyGaussianBlur(5);
// below creates the group, moves the layers to it and merges them. Feel free to just include this part
// at the end of your function if you don't want to use the modified code above. 
// create a new layer set
var groupOne = docRef.layerSets.add();
// move the blur layer inside the layer set and name the layer for posterity
blur.move(groupOne, ElementPlacement.INSIDE);
blur.name = "blur";
// move the newdLayer inside and rename
newdLayer.move(groupOne, ElementPlacement.INSIDE);
newdLayer.name = "newdLayer";
// merge the layer set and name the new layer
var mergedGroup = groupOne.merge();
mergedGroup.name = "newdLayer + blur";
app.preferences.rulerUnits = startRulerUnits;
})();

作为旁注，merge()方法也可供artLayers使用，但根据您的文档的层数和层的顺序，可能需要额外的步骤才能将 2 层与artLayers方法合并。 这是因为artLayersmerge()方法只是将任何活动层与其下方的层合并。 复制图层时，我相信它们位于artLayers集合中的索引 0，这将是"图层"调色板中最顶层的图层。 如果您的源图层尚未处于索引 0，则需要在merge()之前对图层进行排序;
