<h1>Smart Objects</h1>
|
|
|
|
<p>Designers often need to place several copies of the same object into the document
|
|
(e.g. when you want to add multiple snowflakes on the sky). It can be done by creating the first object and then duplicating it
|
|
(and moving copies to the right place).</p>
|
|
|
|
<p>There is a disadvantage in such approach. When you need to modify the object, you will need to modify each copy of the object separately.</p>

<h2>Single Source</h2>
|
|
|
|
<p>PSD format offers a better solution for dealing with many copies of the same object.
|
|
The single source of the image data is created in the background (e.g. the PNG image of the snowflake), and each snowflake layer is linked to
|
|
this single source. Once the source is changed, all layers, that are linked to it, are automatically updated.
|
|
Such layers are called <b>Smart Objects</b>. A Smart Object is a type of a layer.</p>
|
|
|
|
<p>Smart Objects may be linked to the same source, but they don't have to look completely the same.
|
|
Smart Objects can have different positions and transformations (rotation, scale etc.).
|
|
And since they are different layers, they can have different opacity and the layer style.</p>
|
|
|
|
<p>Smart Objects have another advantage. When you have a regular layer, 100 x 100 pixels, and you scale it down to 10 x 10 pixels,
|
|
and then back to 100 x 100 pixels, some image information will be lost.
|
|
The Smart Object would have the image information (100 x 100 px image) stored in the background, so after scaling it down and up again,
|
|
the new image can be recalculated from the source, which never lost any data. It allows us to do <b>nondestructive editing</b>.</p>
|
|
|
|
<h2>Working with smart objects</h2>
|
|
|
|
<p>You can convert any layer (or several layers) to a Smart Object by selecting them and right-click - Convert to Smart Object.
|
|
Selected layers will be removed and inserted into a new PSD file, which will become the source of a new Smart Object, that will be added to the document.</p>
|
|
|
|
<p>Smart Object layers have a little sign in the bottom-right corner of the thumbnail.</p>
|
|
|
|
<img src="https://i.imgur.com/uycgvaL.png" />
|
|
|
|
<p>Double-click the thumbnail of the smart object to edit its source. It will be opened as a separate document.
|
|
When you finish editing the source, press File - Save. All Smart Objects, that are linked to that source, will be updated in the original document.
|
|
Duplicating the smart object would create new Smart Objects, that are still linked to the same source.</p>
|
|
|
|
<p>Let's return to our initial case. We can solve it by drawing a snowflake and converting it to the Smart Object.
|
|
Then, we can duplicate that Smart Object and move copies to different places on the sky. Once we need to change the snowflake,
|
|
we simply double-click any thumbnail of a snowflake, change the source and save it. All snowflakes will be updated.</p>
