<h1>Edit Smart Objects with a Script</h1>
|
|
<div class="entry">
|
|
|
|
<p>Let's have a look at how we can edit Smart Objects from a Script in Photopea or Photoshop.</p>
|
|
<span id="more-325"></span>
|
|
|
|
<p>The basic DOM (Document Object Model) allows us working with a document, create and edit layers, modify their properites, etc.
|
|
But there are many operations, for which appropriate DOM commands do not exist.</p>
|
|
|
|
<p>Photopea and Photoshop can <a href="//www.photopea.com/learn/actions">run actions</a>. An action (one step) consists of two parts:</p>
|
|
<ul>
|
|
<li><b>Name</b> - a string of text, such as "make", "select", etc.</li>
|
|
<li><b>Descriptor</b> - a structured object with additional parameters of the action</li>
|
|
</ul>
|
|
|
|
<p>We can create an action (its name and a descriptor) inside a script. Then, it can be executed using <code>executeAction(Name, Descriptor)</code>.</p>
|
|
|
|
<h2>Open, edit and save a Smart Object</h2>
|
|
<p>The action <b>placedLayerEditContents</b> corresponds to opening a Smart Object.</p>
|
|
|
|
<pre>
|
|
// select a layer that you want to work with
|
|
var l = app.activeDocument.layers.getByName("arrow");
|
|
app.activeDocument.activeLayer = l;
|
|
|
|
executeAction(stringIDToTypeID("placedLayerEditContents"));
|
|
|
|
// now, the Smart Object is an active document, we can work with it
|
|
app.activeDocument.activeLayer.rotate(90);
|
|
|
|
// save the smart object and close it
|
|
app.activeDocument.save();
|
|
app.activeDocument.close();
|
|
</pre>

<a target="_blank" href="//www.photopea.com#%7B%22files%22:%5B%22https://www.photopea.com/api/img2/arrows.psd%22%5D%7D">Try it!</a>
|
|
|
|
|
|
<h2>Convert a layer into a Smart Object</h2>
|
|
<p>The action <b>newPlacedLayer</b> corresponds to clicking Layer - Convert to Smart Object.</p>
|
|
|
|
<pre>
|
|
// select a layer that you want to work with
|
|
var l = app.activeDocument.layers.getByName("ground");
|
|
app.activeDocument.activeLayer = l;
|
|
|
|
executeAction(stringIDToTypeID("newPlacedLayer"));
|
|
</pre>
