DPI = dots per inch. In computer terms, this is equivalent to 'pixels per inch'. That means that for every 'n' pixels, there is an inch. If you set the DPI value to 300, then 300 pixels will equal an inch. Thus, to render an image at 20"x30" at 300 DPI: 20" * 300 DPI = 6000 pixels 30" * 300 DPI = 9000 pixels You would set the dimensions for render to: X(width) = 6000 Y(height) = 9000 DPI = 300 I must warn you that I'm not certain if Poser can handle such render dimensions. Even if it can, expect to be rendering for some hours or days!

C makes it easy to shoot yourself in the foot. C++ makes it harder, but when you do, you blow your whole leg off.
