Detailed Description

Class ON_4iRect For those situations where a Windows SDK RECT or MFC CRect value needs to be used in code that does not link with MFC. If you want a traditional bounding box, use ON_2dBoundingBox.

Constructor & Destructor Documentation

ON_4iRect() [1/5]

ON_4iRect::ON_4iRect ( )

default

Default construction intentionally leaves x and y uninitialized. Use something like ON_4iRect pt(1,2,3,4); or ON_4iRect pt = ON_4iRect::Zero; when you need an initialized ON_4iRect.

Member Data Documentation

bottom

ON__INT32 ON_4iRect::bottom

left

ON__INT32 ON_4iRect::left

NOTE WELL: Windows 2d integer device coordinates have a strong y-down bias and it is common for top < bottom. General 2d bounding boxes have a strong lower < upper / min < max bias. Take care when converting between ON_2iBoundingBox and ON_4iRect. It is intentional that no automatic conversion between bounding box and ON_4iRect is supplied because each case must be carefully considered.
