源码如下：
//批处多个文件
var prefs = new Object()
var sourceFolder = Folder.selectDialog('Please select the imported folder:', Folder(prefs.sourceFolder))
var docs = sourceFolder.getFiles("*.pdf")
for (index in docs) {
doc = docs[index]
//判断输入文件格式是否为PDF
if (doc.name.indexOf('pdf') == -1) {
continue
}
open(File(doc))
var doc = activeDocument
doc.changeMode(ChangeMode.RGB) //图像模式RGB
app.preferences.rulerUnits = Units.MM
activeDocument.resizeImage(120) //保持长宽比，宽为120，高度随宽度变化，默认分辨率
doc.rotateCanvas(90) //顺时针旋转90°
var jpegOptions = new JPEGSaveOptions()
//jpegOptions.embedColorProfile = true
//jpegOptions.formatOptions = FormatOptions.STANDARDBASELINE
//jpegOptions.matte = MatteType.NONE
jpegOptions.quality = 12 //保存质量1~12
saveFile = new File(sourceFolder + '/' + doc.name.split('.')[0] + '副本.jpg')//文件名称
activeDocument.saveAs(saveFile, jpegOptions, true) //保存确认
activeDocument.close(SaveOptions.DONOTS**ECHANGES)//保存后自动关闭
}

//处理单个文件
var prefs = new Object()
var file_name = open(File(openDialog()))
var doc = activeDocument
doc.changeMode(ChangeMode.RGB)//图像模式RGB
app.preferences.rulerUnits = Units.MM
activeDocument.resizeImage(120)
doc.rotateCanvas(90) //顺时针旋转90°
var jpegOptions = new JPEGSaveOptions()
jpegOptions.quality = 12 //保存质量1~12
saveFile = new File("~/desktop/" + doc.name.split('.')[0] + '副本.jpg')//存储至桌面
activeDocument.saveAs(saveFile, jpegOptions, true) //保存确认
activeDocument.close(SaveOptions.DONOTS**ECHANGES)//保存后自动关闭
