Detailed Description

The Transform class is meant to be used for mapping between the local and world coordinate spaces.

• mapFrom(...) will take the input and and return the inverted point in the mapped space.
• mapToWorld(...) functions will take the input and first map it from the local space and then to the world space.

Note

It is assumed that the rect, polygon, point etc... hasn't been transformed when inputted.
