Now we need to add text. That's the most useful part of a PDF, and the easiest. Also the hardest. Sometimes life is like that.

See the code.

Now that we can draw in our PDF, we want to add images. There are two kinds of images, bitmapped and vector. In PDF, images are called XObjects (The X stands for external, meaning defined outside the page). Vector images are easier, since they are just packages of PDF drawing commands, a sort of macro. PDF calls them Forms, since they were originally used to draw the boxes on a printed form.
