The general abstract class Geometry in 2D space describes the common behaviour of all the geometric entities.
All the objects derived from this class can be move with a geometric transformation. Only the transformations which doesn't modify the nature of the geometry are available in this package. The method Transform which defines a general transformation is deferred. The other specifics transformations used the method Transform. All the following transformations modify the object itself. Warning Only transformations which do not modify the nature of the geometry can be applied to Geom2d objects: this is the case with translations, rotations, symmetries and scales; this is also the case with gp_Trsf2d composite transformations which are used to define the geometric transformations applied using the Transform or Transformed functions. Note: Geometry defines the "prototype" of the abstract method Transform which is defined for each concrete type of derived object. All other transformations are implemented using the Transform method.

Transformation of a geometric object. This tansformation can be a translation, a rotation, a symmetry, a scaling or a complex transformation obtained by combination of the previous elementaries transformations. (see class Transformation of the package Geom2d). The following transformations have the same properties as the previous ones but they don't modified the object itself. A copy of the object is returned.
Implemented in Geom2d_BSplineCurve, Geom2d_Hyperbola, Geom2d_BezierCurve, Geom2d_OffsetCurve, Geom2d_Ellipse, Geom2d_TrimmedCurve, Geom2d_Parabola, Geom2d_Line, Geom2d_VectorWithMagnitude, Geom2d_Circle, Bisector_BisecCC, Bisector_BisecPC, Bisector_BisecAna, Geom2d_AxisPlacement, Geom2d_Direction, and Geom2d_CartesianPoint.
