deferred class Geometry from Geom2d inherits TShared from MMgt 

        --- Purpose :
        --  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.

is



  Mirror (me : mutable; P : Pnt2d)
        --- Purpose : Performs the symmetrical transformation of a Geometry
        --  with respect to the point P which is the center of the 
        --  symmetry and assigns the result to this geometric object.
    is static;


  Mirror (me : mutable; A : Ax2d)
        --- Purpose : Performs the symmetrical transformation of a Geometry
        --  with respect to an axis placement which is the axis of the symmetry.
    is static;



  Rotate (me : mutable; P : Pnt2d; Ang : Real)
        --- Purpose : Rotates a Geometry. P is the center of the rotation.
        --  Ang is the angular value of the rotation in radians.
    is static;


  Scale (me : mutable; P : Pnt2d; S : Real) 
        --- Purpose : Scales a Geometry. S is the scaling value.
    is static;


  Translate (me : mutable; V : Vec2d)
        --- Purpose : Translates a Geometry.  V is the vector of the tanslation.
    is static;

  Translate (me : mutable; P1, P2 : Pnt2d)
        --- Purpose : Translates a Geometry from the point P1 to the point P2.
     is static;

  Transform (me : mutable; T : Trsf2d) 
        --- Purpose : 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).
     is deferred;




        --- Purpose : 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.



  Mirrored (me; P : Pnt2d)            returns like me

  Scaled (me; P : Pnt2d; S : Real)     returns like me

  Transformed (me; T : Trsf2d)        returns like me
