Detailed Description

template<class T, class ENABLE = void>
class Cvb::RectLT< T, ENABLE >

Rectangle object.

In contrast to the Rect class this class uses left top of each pixel as anchor point. Therefore right and bottom are not included (i.e. Width = Right - Left and Height = Bottom - Top).

Examples
ShapeFinder2/QtShapeFinder2.
