Detailed Description

template<typename T>
class vtkRect< T >

templated base type for storage of 2D rectangles.

This class is a templated data type for storing and manipulating rectangles. The memory layout is a contiguous array of the specified type, such that a float[4] can be cast to a vtkRectf and manipulated. Also a float[12] could be cast and used as a vtkRectf[3].
