清除原始数据

这个问题我在CSDN写过一篇文章介绍解决方法，可以去看原贴，这里做一个简单的搬运。

贴一下这个脚本的源代码

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();
