There are tons of apps that allow you to manipulate images on your Mac. iPhoto and Preview are two from Apple, and there are lots more available from the Mac App Store and third-party software vendors. What you may not know, however, is that you don’t need a third-party app to do some basic image manipulations with your existing operating system. Using Automator, you can create your own custom image processing plug-ins, which you can run right within the Finder.
If you’ve used Automator before, then you may know that it includes actions for performing basic image manipulation tasks, such as cropping and resizing. Today’s workflow uses one of these built-in actions to apply a filter to selected image files in the Mac OS X Finder.
Today's Automator Service workflow tip involves image files. This workflow will receive selected image files in the Finder, and merge them together to form a multi-page PDF document.
With the help of ThisService, a third-party utility from waffle software, and AppleScript, you can now run Automator workflows from the Services menu in Mac OS X.
Some commercial applications are now making it possible to run your Automator workflows using an Apple Remote or other remote control.
There are literally hundreds of add-on actions available from third-party developers to help extend Automator's capabilities. To find them, you just need to know where to look.
If you're a system administrator, then you may already know that Apple Remote Desktop comes with over 30 Automator actions. But, what you may not know is that you can extend this set of actions even further by installing an additional ARD action pack.
For developers, Automator's reach can be significantly expanded by incorporating your own custom AppleScript, Shell script, Python, or Ruby code into any workflow.
