PS的BUG,原因是因为图片包含了极多的冗余信息,目前2021版本仍未修复。目前可通过其他手段解决,以下为解决方法新建TXT文本文档,复制以下内容进去function deleteDocumentAncestorsMetadata() {whatApp = String(ame);//String version of the app nameif(whatAsearch("Photoshop") > 0) { //Check for photoshop specifically, or this will cause errors//Function Scrubs Document Ancestors from Filesif(!length) {alert("There are no open Please open a file to run this ")return;}if (ExternalOAdobeXMPScript == undefined) ExternalOAdobeXMPScript = new ExternalObject("lib:AdobeXMPScript");var xmp = new XMPMeta( activeDxmpMawData);// Begone foul Document Ancestors!deleteProperty(XMPCNS_PHOTOSHOP, "DocumentAncestors");activeDxmpMawData = serialize();}}//Now run the function to remove the document ancestorsdeleteDocumentAncestorsMetadata();保存后 后缀改为jsx在打开你的大小异常的图片之后,执行操作 文件-脚本-浏览选择这个文件,点击确定后即可恢复正常再次保存和导出图片就是正常大小
