Since I forgot all the basics of math, I'm asking you to help me out with simple task.
I need to rotate text box in PDF. Rotation point is lower left corner, but I need to rotate it as if the rotation point would be on the center.
Since I am using a programming language, I can convert an angle in degrees to its radian equivalent (although I'm not sure if this will help)
Can you help me out to find lower left corner coordinates if rotation point is center?
