The page image is scaled to fit PageRect. To maintain correct proportions, you can use Preview100PercentWidth and Preview100PercentHeight properties.

pgNo must be in range from 1 to PagesCount.

You need to assign source document for printing (AssignSource method) and format pages (FormatPages method) before calling this method.
