Question

PS图层转换为智能对象之后保存，文件体积突然升到几百M，文档里面明明就只有几十M，只有几个图层，究竟是哪里出问题了呢？

Answer 1

使用方法：将下面这段代码复制粘贴到文本工具当中，另存为 Jsx 格式文件。再 PS 打开有问题的文档，「 文件」——「 脚本」——「 浏览...」选择保存的 Jsx 格式文件即可解决。
function deleteDocumentAncestorsMetadata() {
whatApp = String(app.name);//String version of the app name
if(whatApp.search("Photoshop") > 0) { //Check for photoshop specifically, or this will cause errors
//Function Scrubs Document Ancestors from Files
if(!documents.length) {
alert("There are no open documents. Please open a file to run this script.")
return;
}
if (ExternalObject.AdobeXMPScript == undefined) ExternalObject.AdobeXMPScript = new ExternalObject("lib:AdobeXMPScript");
var xmp = new XMPMeta( activeDocument.xmpMetadata.rawData);
// Begone foul Document Ancestors!
xmp.deleteProperty(XMPConst.NS_PHOTOSHOP, "DocumentAncestors");
app.activeDocument.xmpMetadata.rawData = xmp.serialize();
}
}
//Now run the function to remove the document ancestors
deleteDocumentAncestorsMetadata();

把图层前的眼睛都关掉，再保存一次，看下文件体积效果。
