If you are new to scripting for Photoshop, please view our Photoshop
Scripting Basics tutorial for an introduction to Photoshop scripting and a few exercises about
basic JavaScript.
1. The first thing we need to do is check to see if
there is an document. To do this, we'll check to see if the current document has a length. If it
doesn't, it obviously means that there are no opened documents and the script will do nothing instead
of giving an error.
if (documents.length > 0) {
}

2. Now we can enter in the metadata. Type in the following
lines and fill in the settings you would like to use inside the quotations (""):
if (documents.length > 0) {
activeDocument.info.author = "Denny Tang";
activeDocument.info.title = "My Photoshop File";
activeDocument.ownerURL = "http://www.fotofects.com";
activeDocument.category = "Photoshop Scripting";
activeDocument.credit = "Denny Tang";
activeDocument.info.jobName = "Metadata";
activeDocument.info.keywords = ['photoshop', 'scripting', 'fotofects'];
activeDocument.info.city = "Vancouver";
activeDocument.info.provinceState = "BC";
activeDocument.info.country = "Canada";
}
|
|
| 3. Save the script and run it inside Photoshop. View
your File Info (Ctrl+Alt+I) to ensure that the changes are being made. |
|
4. If you look at the script, you'll notice that the "activeDocument" property
gets repeated a lot. A good practice in programming is to optimize the code. We'll create a variable
that will hold the "activeDocument" property.
if (documents.length > 0) {
var doc = activeDocument;
activeDocument.info.author = "Denny Tang";
activeDocument.info.title = "My Photoshop File";
activeDocument.ownerURL = "http://www.fotofects.com";
activeDocument.category = "Photoshop Scripting";
activeDocument.credit = "Denny Tang";
activeDocument.info.jobName = "Metadata";
activeDocument.info.keywords = ['photoshop', 'scripting', 'fotofects'];
activeDocument.info.city = "Vancouver";
activeDocument.info.provinceState = "BC";
activeDocument.info.country = "Canada";
}
|
|
5. Now everytime we want to use the activeDocument
property, we only need to type in "doc". Scripts usually use the activeDocument propertly many
times so consider adding it to your other codes.
if (documents.length > 0) {
var doc = activeDocument;
doc.info.author = "Denny Tang";
doc.info.title = "My Photoshop File";
doc.ownerURL = "http://www.fotofects.com";
doc.category = "Photoshop Scripting";
doc.credit = "Denny Tang";
doc.info.jobName = "Metadata";
doc.info.keywords = ['photoshop', 'scripting', 'fotofects'];
doc.info.city = "Vancouver";
doc.info.provinceState = "BC";
doc.info.country = "Canada";
}
|
|
6. If you will be changing the metadata more than once,
it's a good idea to create a function out of it.
function setMetaData() {
if (documents.length > 0) {
var doc = activeDocument;
doc.info.author = "Denny Tang";
doc.info.title = "My Photoshop File";
doc.ownerURL = "http://www.fotofects.com";
doc.category = "Photoshop Scripting";
doc.credit = "Denny Tang";
doc.info.jobName = "Metadata";
doc.info.keywords = ['photoshop', 'scripting', 'fotofects'];
doc.info.city = "Vancouver";
doc.info.provinceState = "BC";
doc.info.country = "Canada";
}
}
setMetaData();
