I am looking for some insight on how to accomplish a few goals related to PDFs I am working with. Here are a few of the things I am looking to do: 1. The ability to actually make images such as the one attached or to be able to make additions to the attached pdf such as adding further coloration. 2. I would like to be able to highlight words or parts of the pdf as if I were reading out of a textbook. The ability to make annotation would be great; I am aware of the fact that adobe reader allows users to add little text bubbles, but they are pretty annoying. The closest I have come to this is formulate as TJ Riley has suggested, but while it is a app that gets the job done, it is pretty rough. Free to cheap is always better, but I will pay for what I really want. Any and all suggestions are more than appreciated. I will respond asap if you have follow-up questions.
