PS大文件无压缩保存

操作步骤：

1.

这是文件的尺寸，不大也不小

2.

www.16xx8.com

导出jpg可以看到，目前一张jpg差不多42 M

3.

然后导入制作好的文件，通过脚本导入。导入后ps会卡顿一小会，等正常后文件就恢复正常了。（因为内容问题，所以我把内容覆盖掉了）

4.

最后重新导出，可以看到文件已经是370 K 了。

5.文件制作：

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();

用记事本粘贴以上代码后另存，后缀改为JSX，即（名字.jsx）后打开问题文件，文件-脚本-浏览-载入JSX格式文件即可。
