Script to add Image Size to Description field to include in Printing Marks

[TaraRebeka]

Hi all,

Any help appreciated on this. I'm looking for a script that will add this info:

Into the Description field:

Allowing it to display in a printout when the Description field is checked in the Printing Marks window:

Thanks!

The following script will do this for a single open/active document.

P.S. It's ppi – not dpi, you can change that yourself if you disagree!  :]

Legacy:

/*
Add Document Dimensions & Resolution to Description Metadata of Open Document.jsx

*/

#target photoshop

// Rounded to 1 decimal place
var theDims = Math.round(activeDocument.width.as('in') * 10) / 10 + "in x " + activeDocument.height.as('in').toFixed(1) + "in @" + activeDocument.resolution + "ppi";

activeDocument.info.caption = theDims;

Or current:

*/

#target photoshop

// Rounded to 1 decimal place
var theDims = Math.round(activeDocument.width.as('in') * 10) / 10 + "in x " + activeDocument.height.as('in').toFixed(1) + "in @" + activeDocument.resolution + "ppi";

if (ExternalObject.AdobeXMPScript === undefined) ExternalObject.AdobeXMPScript = new ExternalObject("lib:AdobeXMPScript");
var xmp = new XMPMeta(activeDocument.xmpMetadata.rawData);
xmp.deleteProperty(XMPConst.NS_DC, 'description');
xmp.setProperty(XMPConst.NS_DC, 'description', theDims);
app.activeDocument.xmpMetadata.rawData = xmp.serialize();

You could automate this when opening a file using the Script Events Manager:

Alas, there seems to be no real room for disagreement here.

Thanks so much! It worked like a charm.

@TaraRebeka – You're welcome!

Curious - do you know why this script wouldn't work with Photoshop Elements? I had a coworker who wanted to use and it kicked back this:

Thanks.

@TaraRebeka 

My natural response is that Photoshop Elements isn't Photoshop.

 I don't use Elements so I can't test. That being said, one could try simplifying the code to troubleshoot. Example, replace the original variable with this troubleshooting version which simplifies the previous to only show the resolution:

var theDims = activeDocument.resolution + "ppi";

If that works, then the width and height could be checked and so on.

I also provided an Adobe Bridge version that could alternatively be used.

Adobe Bridge is better suited to such things than Photoshop IMHO.

As I don't normally script Bridge, this hack is a little rougher than I would like (PNG files are not supported).

Be aware that Save for Web will strip this out unless you use the All Metadata option. I write product weight into this field using a script, but also write it into the Headline field of my master PSD files. I have a second script that pulls the Headline data and writes it back into Description. That way I don't have to manually reenter the weights on my finished JPEG files.
