Question

I have a been trying to do a search feature in a PDF application. I read the Quartz 2d guide in iphone reference library. And so much has been said about the “pdf operators”. It’s by using them that everything is done, by using call-backs for them.

For info about pdf operators, we should read pdf reference of adobe. But it’s very vast. Can anyone give me an idea of what these operators are (OR how to get an idea in studying them) and which of them I will require for my “search a string feature in pdf”?

Answer 1

I’ve been searching for the same thing and today I found this post that has some clues:

Looks like the operators are “TJ” and “Tj”.
