photoshop 용량 큰 PSD 파일 수정하기(?)

증상 : 이미지 크기가 작은데 이상하게 PSD 파일 용량이 큼

원인 : 특정 이미지에서 얻어온 EXIF 정보 중 XMP 데이터 오염(?)

자세히 : photoshop:DocumentAncestors하위의 rdf:Bag 세부 내용이 넘쳐남

<?xpacket begin="" id="..."?> <x:xmpmeta xmlns:x="adobe:ns:meta/" x:xmptk="Adobe XMP Core 5.0-c060 61.134777, 2010/02/12-17:32:00        ">    <rdf:RDF xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#">       <rdf:Description rdf:about=""             xmlns:xmp="http://ns.adobe.com/xap/1.0/">          <xmp:CreatorTool>Adobe Photoshop CC 2014 (Windows)</xmp:CreatorTool>          <xmp:CreateDate>2018-02-27T09:17:54+09:00</xmp:CreateDate>          <xmp:MetadataDate>2018-02-27T09:17:55+09:00</xmp:MetadataDate>          <xmp:ModifyDate>2018-02-27T09:17:55+09:00</xmp:ModifyDate>       </rdf:Description>       <rdf:Description rdf:about=""             xmlns:photoshop="http://ns.adobe.com/photoshop/1.0/">          <photoshop:ColorMode>3</photoshop:ColorMode>          <photoshop:ICCProfile>sRGB IEC61966-2.1</photoshop:ICCProfile>          <photoshop:DocumentAncestors>             <rdf:Bag>                <rdf:li/>                <rdf:li>0</rdf:li>                <rdf:li>...</rdf:li>                <rdf:li>...</rdf:li>

해결방법

1. PSD 파일

File - Script - Script Events Manager

remove.jsx 로 저장 후(adobe javascript) export나 save에 연결해주면 끝!

// https://forums.adobe.com/message/8511978#8511978 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();
