BoundingBox2D

Canonical path: NemAll_Python_Geometry.BoundingBox2D

Representation class for 2D bounding box.

Bounding box work correct only if m_Min <= m_Max. It means that X coordinate of m_Min is less then or equal to X coordinate of m_Max(m_Min.X() <= m_Max.X()) and Y coordinate of m_Min is less than or equal to Y coordinate of m_Max(m_Min.Y() <= m_Max.Y()).
