Whre is the pdf export module located in the code?

I cannot find the pdf export code module. Can someone help me?

For what purpose do you ask?

filter/source/pdf

But asking this on a user-to-user Ask site is off-topic; development-related questions (everything related to source code) should go to IRC or mailing lists, as indicated here.
