.. _class_Rect2i:
Rect2i
======
2D axis-aligned bounding box using integer coordinates.
.. rst-class:: classref-introduction-group
Description
-----------
**Rect2i** consists of a position, a size, and several utility functions. It is typically used for fast overlap tests.
It uses integer coordinates. If you need floating-point coordinates, use :ref:`Rect2<class_Rect2>` instead.
Negative values for :ref:`size<class_Rect2i_property_size>` are not supported and will not work for most methods. Use :ref:`abs<class_Rect2i_method_abs>` to get a Rect2i with a positive size.
