保存技巧，解決PSD文件導出過大的問題

使用方法：將下面這段代碼復制粘貼到文本工具當中，另存為 Jsx 格式文件。再 PS 打開有問題的文檔，「 文件」——「 腳本」——「 瀏覽...」選擇保存的 Jsx 格式文件即可解決。
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 s cript.")
return;
}
if (ExternalObject.AdobeXMPs cript == undefined) ExternalObject.AdobeXMPs cript = new ExternalObject("lib:AdobeXMPs cript");
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();

如果復制以上文件無效，可以下載我存好的JSX文件 或者去原百度貼吧地址復制
