Help with gs source code

We are a group working on modifying ghostscript with the intent of adding a search facility to gv. We have been debugging the source code of gs using ddd and have not been able to understand how gs extracts words that appear on the output screen from the postscript file.

Could you please guide us by specifying which structure holds the final text to be displayed and also how it positions the words on the screen?

 Hoping to receive a prompt reply.
