Description
This is the documentation of the GEF4 Geometry API. You can find a small tutorial for the API here.
Geometric figures
This diagram depicts the interface hierarchy which underlies the individual geometry classes. In turn, the inheritance hierarchy classifies the figures by their construction type. So that many operations are generalized in a few abstract classes.

Conversions (From/To AWT/SWT/Geometry)
From SWT to Geometry
Important. Very easy via the toSWT...() methods.
From AWT to Geometry
From Geometry to AWT

From SWT to AWT
Affine transformations
Via projective geometry. All matrices can be combined before applying them to the particular shape.
