Thank you in advance.

I have a script that resizes images, it works perfectly, but it doesnt transfer or copy the metadata of each file resized.

I need to keep the metadata that the file has. please help. here is the script that i have.

// Resize based on height. otherwise, resize based on width
doc = app.activeDocument;

// change the color mode to RGB. Important for resizing GIFs with indexed colors, to get better results
doc.changeMode(ChangeMode.RGB);

// these are our values for the end result width and height (in pixels) of our image
var fWidth = 1920;
var fHeight = 1080;

// do the resizing. if height > width (portrait-mode) resize based on height. otherwise, resize based on width
if (doc.height > doc.width) {
doc.resizeImage(null,UnitValue(fHeight,"px"),null,ResampleMethod.BICUBIC);
}
else {
doc.resizeImage(UnitValue(fWidth,"px"),null,null,ResampleMethod.BICUBIC);
}

// our web export options
var options = new ExportOptionsSaveForWeb();
options.quality = 75;
options.format = SaveDocumentType.JPEG;
options.optimized = true;

var doc = activeDocument;
var f = new Folder(doc.path+'/New folder');
if (!f.exists) {
f.create();
}
// var newName = 'Web.'+doc.name+'.jpg';
var newName = doc.name;
doc.exportDocument(File(doc.path+'/New folder/'+newName),ExportType.SAVEFORWEB,options);// /
app.activeDocument.close(SaveOptions.DONOTSAVECHANGES);

    There are numerous ways to batch resize images. Photoshop has a couple built-in, you can use Image Processor Pro, or there are loads of scripts floating around. In Save for Web, you need to include All Metadata. This is not a scriptable option so you might try exporting with this option set to see if it is sticky.

     

    Using EXIFTool is also an option if some fields get left behind.

     

    Finally, below is a demo Bridge script to copy all metadata from one file to multiple other files. You could probably adapt this to Photoshop.

      The problem is the Export Save for Web step, which is stripping out the metadata as it uses DOM code.


      You need to replace the DOM code for Export Save for Web with Save As... Either DOM code or AM code, or possibly use ScriptingListener recorded AM code for Export Save for Web as it can capture the All Metadata option which can't be set via DOM code.

       

      Here's an example of your original code using DOM code for Save As:

       

      // Resize based on height. otherwise, resize based on width
var doc = app.activeDocument;

// change the color mode to RGB. Important for resizing GIFs with indexed colors, to get better results
doc.changeMode(ChangeMode.RGB);

// these are our values for the end result width and height (in pixels) of our image
var fWidth = 1920;
var fHeight = 1080;

// do the resizing. if height > width (portrait-mode) resize based on height. otherwise, resize based on width
if (doc.height > doc.width) {
doc.resizeImage(null,UnitValue(fHeight,"px"),null,ResampleMethod.BICUBIC);
}
else {
doc.resizeImage(UnitValue(fWidth,"px"),null,null,ResampleMethod.BICUBIC);
}

// Save As options
var jpgOptns = new JPEGSaveOptions();
    jpgOptns.formatOptions = FormatOptions.OPTIMIZEDBASELINE; // STANDARDBASELINE
    jpgOptns.embedColorProfile = true;
    jpgOptns.matte = MatteType.NONE;
    jpgOptns.quality = 10;

var f = new Folder(doc.path + '/New folder');
if (!f.exists) {
f.create();
}

var newName = doc.name.replace(/\.[^\.]+$/, '');
app.activeDocument.saveAs(new File(f + '/' + newName + '.jpg'), jpgOptns, true, Extension.LOWERCASE);
app.activeDocument.close(SaveOptions.DONOTSAVECHANGES);

       

      One can also convert to sRGB and do many other things if needed.

       

       

      Edit: Here is a version using trimmed AM code for Export Save for Web, including the All Metadata entry:

       

      // Resize based on height. otherwise, resize based on width
var doc = app.activeDocument;

// change the color mode to RGB. Important for resizing GIFs with indexed colors, to get better results
doc.changeMode(ChangeMode.RGB);

// these are our values for the end result width and height (in pixels) of our image
var fWidth = 1920;
var fHeight = 1080;

// do the resizing. if height > width (portrait-mode) resize based on height. otherwise, resize based on width
if (doc.height > doc.width) {
doc.resizeImage(null,UnitValue(fHeight,"px"),null,ResampleMethod.BICUBIC);
}
else {
doc.resizeImage(UnitValue(fWidth,"px"),null,null,ResampleMethod.BICUBIC);
}

var f = new Folder(doc.path + '/New folder');
if (!f.exists) {
f.create();
}

var newName = doc.name.replace(/\.[^\.]+$/, '');

// Export Save for Web - Include All Metadata
function c2t(s) {
    return app.charIDToTypeID(s);
}
function s2t(s) {
    return app.stringIDToTypeID(s);
}
var descriptor = new ActionDescriptor();
var list = new ActionList();
descriptor.putBoolean( c2t( "DIDr" ), true );
descriptor.putPath( s2t( "in" ), new File( f ) );
descriptor.putString( s2t( "pathName" ), f + '/' + newName + '.jpg');
descriptor.putEnumerated(s2t("format"), c2t("IRFm"), s2t("JPEG"));
descriptor.putInteger(s2t("quality"), 75);
descriptor.putBoolean( s2t( "optimized" ), true );
descriptor.putEnumerated(c2t("SWmd"), c2t("STmd"), c2t("MDAl"));
descriptor.putObject( s2t( "using" ), s2t( "SaveForWeb" ), descriptor );
executeAction( s2t( "export" ), descriptor, DialogModes.NO );

app.activeDocument.close(SaveOptions.DONOTSAVECHANGES);
