41 |
This class represents a transformation for points, that is a combination of scale, offset, and rotation. |
|
42 |
It is implemented as a 2x3 matrix containing the transformation from the local coordinate system in the global coordinate system. |
|
43 |
Thus, transforming points from local to global coordinates is fast and cheap, |
|
44 |
whereas transformations from global to local coordinate systems are relatively expensive. |
|
45 |
||
46 |
Implementation Note: It is assumed that the transformation deals with Integer points. |
|
47 |
All transformations will return Integer coordinates (even though float points may be passed in here). |
