IIXC_Page::Rect Property
From PDF XChange PDF SDK
Fills the RECT structure with page dimensions, ie, left and top fields will be set to zero, right - to the page width, and bottom to the page height.
Syntax
HRESULT get_Rect([out, retval] RECT* stRect);
Remarks
Many IIXC_Page object methods have a stRect parameter that specifies a portion of the page to be processed. When this parameter is NULL, the entire page is processed. Some languages, like C#, cannot easily pass NULL and they need to pass a valid RECT that covers entire page, and this property may be very helpful then.
