I am building PDF files by hand (custom source code). My problem is that text is always originated at the bottom left corner (minus descent). I need to be able to originate text in the center X and Y coordinates. Since the PDF reference manual gives no indication of a method to change the origin, I am trying to accomplish this using normal graphic calculations with the same font. However, it appears the font that adobe uses internally for rendering the PDF (Helvetica) is not the same as the Helvetica font on my OS, and I am therefore getting differing measurements for a given string's dimensions. Any idea how I can either change the origin in the PDF, or accurately measure a string to shift the placement according to adobe's default origin?
