PhotoShop版本：Photoshop CC 2020
低版本可能会影响对象定义

----------
##一、脚本的使用
###1.HelloWolrd 走起
```
---->[Hello.js]-----------------
Alert("Hello World");
```

##二、从面向对象的角度来看PhotoShop
###0.对象：app
> 将整个app看做一个对象，它拥有着众多的方法和属性,以此可以获取信息和操作图片
先来看一下app对象中的几个对象,找点感觉
```
app {//整个PS软件对象
    name,//软件名称
    version,//软件版本
    documents:{},//打开的文件的信息
    fonts:{}//系统字体
    recentFiles:{},//所有的打开文档对象(数组)
    activeDocument:{}//当前激活的文档对象
}
```
###1.获取名称和版本号+操作提示音:`app.beep()`
```
---->[info.js]-----------------
var msg = app.name + "\r\n 版本:" + app.version;
alert(msg);
app.beep() //执行播放提示音效果：叮咚
```

###2.打开的文件的信息：app.documents
![](https://assets.guaishow.cn/Picgo/20200118100422.png)
```
var docs = app.documents;
var msg = "";

for (var i = 0; i < docs.length; i++) {
    msg +=
        "名称:" + docs[i].name + "\r\n" +
        "宽/像素:" + docs[i].width + "\r\n" +
        "高/像素:" + docs[i].height + "\r\n";
}
alert(msg);
```
###3.列出字体:`app.fonts`
![](https://assets.guaishow.cn/Picgo/20200118100511.png)
```
var fonts = app.fonts;
var msg = "";

for (var i = 0; i < fonts.length; i++) {
    msg += "序号:" + (i + 1) + "  字体:" + fonts[i].name + "\r\n";
}
alert(msg);
```
###4.最近打开的文件:`app.recentFiles`
![](https://assets.guaishow.cn/Picgo/20200118100552.png)
```
var cFiles = app.recentFiles;
var msg = "";
for (var i = 0; i < cFiles.length; i++) {
    msg += (i + 1) + ":" + cFiles[i].name + "\r\n";
}
alert(msg);
```
![](https://assets.guaishow.cn/Picgo/20200118100616.png)
###5.当前激活的文档对象:`app.activeDocument`
![](https://assets.guaishow.cn/Picgo/20200118100633.png)
```
var doc = app.activeDocument;
msg = "名称:" + doc.name + "\r\n" +
    "宽/像素:" + doc.width + "\r\n" +
    "高/像素:" + doc.height + "\r\n";
alert(msg);

```
----------------
##三、文件操作相关
1.打开图片:`open(File)`
```
var img = File("J:\\Java\\Android\\TolyGithub\\TolyTest\\toly_test\\src\\main\\res\\mipmap-xxhdpi\\bg_10.jpg");
var ok = confirm("打开图片?");
if (ok) {
    open(img)
}
```
![](https://assets.guaishow.cn/Picgo/20200118100714.png)
###2.打开文件夹下所有图片
```
var imgFolder = File("J:\\Java\\Android\\TolyGithub\\TolyTest\\toly_test\\src\\main\\res\\mipmap-xxhdpi");
var files = imgFolder.getFiles();
for (var i = 0; i <files.length; i++) {
    var file = files[i];
    if (file instanceof File) {
        open(file);
    }
}
```
![](https://assets.guaishow.cn/Picgo/20200118100739.png)
###3.拷贝当前文档并打开
```
var doc = app.activeDocument;//当前文件对象
doc.duplicate(app.activeDocument.name + "-copy", 1);//拷贝当前文档并打开
```
![](https://assets.guaishow.cn/Picgo/20200118100800.png)
###4.文件另存为:`app.activeDocument.saveAs`
```
var doc = app.activeDocument;//当前文件对象
var outPath = new File("G:\\Photo\\龙少.png");
var options = PNGSaveOptions;//保存png模式
var asCopy = true;//副本方式保存
var extensionType = Extension.LOWERCASE;//拓展名小写
doc.saveAs(outPath, options, asCopy, extensionType);
alert("保存完成")
```

###5.压缩并保存图片(web)
> 直接保存的png 有11.1M, web导出的0.3k,虽然效果上有些失色,还是很有价值的。
![](https://assets.guaishow.cn/Picgo/20200118100846.png)
```
//压缩保存gif
var doc = app.activeDocument;//当前文件对象
var path = new File("G:\\Photo\\龙少.gif");
var eop = new ExportOptionsSaveForWeb();//web图片导出配置
eop.transparecy = false;//是否正常透明度
eop.includeProfile = true;//是否包含内置颜色配置文件
eop.lossy = 0;//有损压缩程度
eop.colors = 256;//色彩量
eop.colorReduction = ColorReductionType.SELECTIVE;////减低颜色深度算法:可选择
eop.formate = SaveDocumentType.COMPUSERVEGIF;//导出格式FIF
eop.ditherAmount = 0;//像素抖动值
eop.dither = Dither.NOISE;//杂色
eop.palette = Palette.LOCALADAPTIVE;//局部（随样性）
doc.exportDocument(path, ExportType.SAVEFORWEB, eop);
alert("保存完成:" + path);

//压缩保存jpeg
var doc = app.activeDocument;//当前文件对象
var filePath = new File("G:\\Photo\\龙少.jpeg");
var eop = new ExportOptionsSaveForWeb();//web图片导出配置
eop.quality = 60;//图片质量
doc.exportDocument(filePath, ExportType.SAVEFORWEB, eop);
alert("保存完成:" + filePath);

//压缩保存png
var doc = app.activeDocument;//当前文件对象
var filePath = new File("G:\\Photo\\龙少-compressed.png");
var eop = new ExportOptionsSaveForWeb();//web图片导出配置
eop.PNG8 = true;//png 8彩
doc.exportDocument(filePath, ExportType.SAVEFORWEB, eop);
alert("保存完成:" + filePath);
```

##四、一些简单操作
###1.创建新文件
```
//创建新文件
var width = 1080;//宽
var height = 1920;//高
var resolution=72;//分辨率
var fileName="phone";//名称
var mode = NewDocumentMode.RGB;//色彩模式
var fillColor = DocumentFill.TRANSPARENT;//背景填充颜色
var pixelAspectRatio=1;//像素比率
app.documents.add(width, height, resolution, fileName, mode, fillColor, pixelAspectRatio);
```

###2.添加文字图层
```
//创建文字图层
var doc = app.documents.add(500, 200);
var artLayer = doc.artLayers.add();
artLayer.kind = LayerKind.TEXT;

var textItem = artLayer.textItem;//文字条目
textItem.contents = "张风捷特烈";//文字内容
textItem.size = 40;
artLayer.translate(0, 100);
```
![](https://assets.guaishow.cn/Picgo/20200118100932.png)
###3.获取当前文件的所有图层

```
//获取图层对象
var layers = app.activeDocument.artLayers;
var msg = "";
for (var i = 0; i < layers.length; i++) {
    var layer = layers[i];
    msg += i + "--图层名称：" + layer.name + "\r\n";
}
alert(msg);
```
###4.获取图层尺寸
```
var layer = app.activeDocument.activeLayer;//活动图层
alert(layer.bounds);
```
![](https://assets.guaishow.cn/Picgo/20200118101029.png)
###5.当前激活图层：色彩平衡
```
var layer = app.activeDocument.activeLayer;//活动图层
layer.adjustColorBalance([-39,-81,0], [-44,50,-52], [0,0,0], true);//阴影、中间调、高光
```
![](https://assets.guaishow.cn/Picgo/20200118101047.png)
###6.前景色和背景色的修改
```
var ok = confirm("是否随机设置前景色和背景色?");
if (ok) {
    //前景色
    app.foregroundColor.rgb.red = Math.random() * 255;
    app.foregroundColor.rgb.green = Math.random() * 255;
    app.foregroundColor.rgb.blue = Math.random() * 255;
    //背景色
    app.backgroundColor.rgb.red = Math.random() * 255;
    app.backgroundColor.rgb.green = Math.random() * 255;
    app.backgroundColor.rgb.blue = Math.random() * 255;
}
```
