I am trying to programmatically add a rectangle annotation to a PDF document. I am successfully able to create the annotation, its associated popup, etc. I am, however, having trouble creating its AP object. I need to know how to create the BBox attribute's
coordinates (/BBox [ 0 0 135 59 ]) based on the user space coordinates of the rectangle. I also need to know how to create the AP stream itself. A rectangle's AP stream is usually in the format:

q 0 0 1 RG []0 d 2 w 1 1 83.351 40.0385 re S Q

What I need to know is how to come up with the 83.351 and 40.0385, which obviously are related to the rectangle s size. These appear to also be related to
the BBox coordinates which I enquired about above.

Any help would be very much appreciated
