Detailed Description

template<typename T>
class sp::scene::Transformation2D< T >

2D transformation class. This is not a base class. Unlike 3D transformation in 2D, most transformations are done without matrices or some kind of that. But it can be used for a more structured transformation. This transformation is stored as position (2D Point), rotation (Single value) and scale (2D Size).

size2d

Since:

Version 3.2
