Sort Duplex Scan PDF

This Python script combines two PDF documents generated by scanning a stack of duplex-printed papers with a single-face scanner. It works with python 2.7 and up, and depends on the Python Package pdfrw.

Installation

Dependencies

When running the script without the Automator wrapper, the pdfrw can be installed via pip

pip install pdfrw

Running the script as a Service through Automator requires using the OS default Python installation /usr/bin/python. The dependency can be installed using easy_install but requires super user privileges.

sudo /usr/bin/easy_install pdfrw

Automator Service

Doubleclick on the workflow and it should allow you to install it as a Service. If this does not work, follow these steps:

1. Open the Workflow in Automator.app
2. Via the Menu: File -> Convert to... -> Service
3. At the top of the Workflow, choose Accepts PDF Files and Finder.app
