Smart Layer Export

Smart layer export is an alternative to traditional slicing found in image editors.  Name your layers or layer groups like you would a normal image file, and then export them out of Acorn without any cumbersome tricks.  You can even tell Acorn to export your images every time you save.  

This tutorial will use the example of smart layer export being used on an image of 'submit' buttons.  You can download the sample image here: FancySubmitButtonSmartExport.acorn.  This is what the sample image looks like:


The sample image file has two buttons meant for a website.  They are different sizes so the smaller one can be shown on regular screens, and the larger one for Retina class devices (such as an iPhone 4, iPad 3, or a Retina MacBook Pro).

If you were to use the File ▸ Exportmenu item to save the image as a PNG, you would still have to slice up the image into two different parts- and you'd have to save the image again.  Wouldn't it be great if you could tell Acorn that you would like to save out a layer as a specific file name?  This is where smart layer export comes in handy.

Smart Layer Export Steps:

To see how this is done, take a look at the layers list of the example image:


There are a total of 11 layers.  You'll notice that two layer groups are named as files.  When you use smart layer export, Acorn will use the layers which are part of the group (and only that group) to make a brand new image.  Since the "Background" layer is outside of both groups, it will not be used when exporting.  However, if you renamed "Background" to "Background.png", there would be 3 files exported out instead of 2.

Here's another image, showing the original button image, along with the two images created from the smart layer export:
