ps降低图片存储大小方法、图片压缩方法，清除图片冗余
1. 将图片用PS打开。
2. 快捷键Ctrl+Shift+Alt+S
品质越小，图片占的内存就越小，但是图片的清晰度就会越低
清除图片冗余，
1.将以下代码放在txt文档，然后改后缀jsx格式
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();
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();
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) {

return;
}
if (ExternalObject.AdobeXMPScript == undefined) ExternalObject.AdobeXMPScript = new ExternalObject("lib:AdobeXMPScript");
var xmp = new XMPMeta( activeDocument.xmpMetadata.rawData);
