Automator action “Rotate Images” is incredibly memory-intensive

automatorimage processingmemory

I'm building an automator workflow to rotate images. It seems that sips and other image rotation possibilities do not actually change the bits of the image, but just flip a switch for orientation, and I need to change the image bits. Anyway, I'm building the workflow using the "Rotate Images" action and it seems like it uses a ton of memory when you rotate multiple images (which is kind of the point of an automator action). Apparently, after it rotates an image, it retains the memory and only releases it after the entire action is complete. And so I end up running out of ram and also swap!

Is there a solution to force it to release memory?

Here is the some applescript code I wrote to rotate an image right 90. You may only rotate right. So if you want to rotate left 90 to enter you will have to rotate right 270.

 Save as an Application Bundle.  Don't check anything.

 Shows log statement.

 It is easier to diagnose problems with debug information. I suggest adding log statements to your script to see what is going on.  Here is an example.

For testing, run in the Script Editor.
    1) Click on the Event Log tab to see the output from the log statement
    2) Click on Run
