PDF Side by Side Comparison?

Hello, I am looking for a .Net Comparison API, which can compare two PDF files and show the results side by side. The following image is an example output (from Acrobat Desktop, but shoes the concept)

Please have a look at this documentation article and this open-source example project.
How document comparison API works?
