Problems converting PDF and extracting Images

[Dustin T.. Clifford]

All,

I'm new to PDFBox and I'm having some trouble converting the pages in a PDF to 
JPEG images. The issue seems to be more than similar to the linked thread.

 http://markmail.org/message/em3rrqz24ip3c7s5

I have used ImageMagick CLI tools to ensure that the PDF is not the issue and 
everything renders just fine. Below, I have linked two images of the same page 
(one created by image magick CLI and one by PDFBox).

 http://www.sitesoftllc.net/images/imagemagick.jpg    (ImageMagick Created)
 http://www.sitesoftllc.net/images/pdfbox.jpg         (PDFBox Created)

My next attempt to determine if I was doing something wrong was to extract the 
images in the PDF. Those appear to be discolored as well (I have linked the 
result below).

Has anybody experienced this? Is there a solution? Please, find my code copied 
below. I appreciate any help in finding out what I'm doing wrong.
