 In this program, we are going to see how we can extract PDF information like PDF document information like author, created date, bookmarks from the PDF. So here is our game plan, we are going to create an object of the info extractor class, we are going to load document and we can, we are then just fetching the information whatever we like, like the author, created name, producer, subject, extractor. So we are already having one PDF file here and let's see what we can fetch out of it. First we are going to have the object of this info extractor class, we are going to pass the registration name and key here. Now let us load document, load document.file, sample, program3, PDF and just display the information like we can get the author name from the extractor.author, we can get a creator name by using the creator likewise. Let us see what we can fetch it. Now it is compelling like this file doesn't exist, it's weird, I'm sure, okay, we need to have the copy always here, let us see now, okay. So in the author name, it is displaying some trial information because we are using the demo keys, the creator is none, producer is kia, PDF, we have the subject, title, creation date. So this line will be removed after we use the actual keys. So I guess the code is pretty simple here.
