About:

The PDF Thumbnail Generator is designed to allow for easy creation of
thumbnails from PDF files.

There are two versions:

 - Create Thumbnails of the First Page of Many PDFs:
     Creates a thumbnail of the first page of every PDF that is selected
     when the workflow is run

 - Create Thumbnails of Every Page of a Single PDF:
     Creates a thumbnail of every page of a PDF, allows for interactive
     saving of desired pages.

To run, select the Workflow application with the robot icon.  The document
icon will open the source in Automator if you choose to edit the
workflow.

Create Thumbnails of the First Page of Many PDFs:

When run, you will be able to select multiple PDF files.  You will then be
prompted for some options; such as image size and file type.  The thumbnails
will be saved in the same folder as the source PDF files, with the name
"Copy of xxx.jpeg"

The thumbnails will always be the first page of each PDF file.

This workflow might also work with other kinds of files, although it was
only tested with PDFs.  I will only support this script with PDF files.


--------------

Create Thumbnails of Every Page of a Single PDF

Sometimes, the thumbnails automatically generated from the first page of a
PDF file aren't what's needed.  In some instances, the best page for a
thumbnail isn't the first page.  Other times, the page needs rotation before
being saved as a thumbnail.

This workflow is designed for when more care must be taken with generating
a thumbnail.

When the workflow is run, you will be able to select a single PDF file.
You will then be prompted for many options, such as image type, size, and
compression quality.

Some steps might take a few seconds.  If you have a large PDF, you might
have to wait a minute or two.

Once resizing is complete, the PDF will open in four different Preview
windows.  Each window will have a different rotation of the PDF, either 0,
90, 180, or 270 degrees.  The pages will be out-of-order.  In Preview, you
will need to select the page(s) that you want to save, and then navigate
to File -> Save As.
