Assistance upgrading PDFBox from v1.8 to v2.0

[Evan Stansel]

Hello,

I am working with an automation script that compares PDF files using PDFBox. 
The script has been written for v1.8. We'd like to upgrade the script to v2.0. 
I attempted to do this myself using the migration guide but ran into issues 
along the way. I've attached the script above (just a function). Hoping to get 
some input as to what primary changes need to happen. As a side note, this is 
in Javascript and this is written to be used in TestComplete (full set of 
scripts can be found here: 
https://support.smartbear.com/articles/testcomplete/testing-pdf-files-with-testcomplete).

Thank you,
Evan Stansel

      if (!pic_1.Compare(pic_2, false, 5, false, 5, maskImg))
      {
        // If the images are different...
        // Post image differences to the log
        Log.Picture(pic_1.Difference(pic_2, false, 5, false, 5, maskImg));
