| void | Mirror (const gp_Pnt2d &P) |
| | 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.
|
| |
| void | Mirror (const gp_Ax2d &A) |
| | Performs the symmetrical transformation of a Geometry with respect to an axis placement which is the axis of the symmetry.
|
| |
| void | Rotate (const gp_Pnt2d &P, const Standard_Real Ang) |
| | Rotates a Geometry. P is the center of the rotation. Ang is the angular value of the rotation in radians.
|
| |
| void | Scale (const gp_Pnt2d &P, const Standard_Real S) |
| | Scales a Geometry. S is the scaling value.
|
| |
| void | Translate (const gp_Vec2d &V) |
| | Translates a Geometry. V is the vector of the translation.
|
| |
| void | Translate (const gp_Pnt2d &P1, const gp_Pnt2d &P2) |
| | Translates a Geometry from the point P1 to the point P2.
|
| |
| virtual void | Transform (const gp_Trsf2d &T)=0 |
| | Transformation of a geometric object. This transformation 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.

 Public Member Functions inherited from Standard_Transient |
| | Standard_Transient () |
| | Empty constructor.
|
| |
| | Standard_Transient (const Standard_Transient &) |
| | Copy constructor – does nothing.
|
| |
| Standard_Transient & | operator= (const Standard_Transient &) |
| | Assignment operator, needed to avoid copying reference counter.
|
| |
| virtual | ~Standard_Transient () |
| | Destructor must be virtual.
|
| |
| virtual const opencascade::handle< Standard_Type > & | DynamicType () const |
| | Returns a type descriptor about this object.
|
| |
| Standard_Boolean | IsInstance (const opencascade::handle< Standard_Type > &theType) const |
| | Returns a true value if this is an instance of Type.
|
| |
| Standard_Boolean | IsInstance (const Standard_CString theTypeName) const |
| | Returns a true value if this is an instance of TypeName.
|
| |
| Standard_Boolean | IsKind (const opencascade::handle< Standard_Type > &theType) const |
| | Returns true if this is an instance of Type or an instance of any class that inherits from Type. Note that multiple inheritance is not supported by OCCT RTTI mechanism.
|
| |
| Standard_Boolean | IsKind (const Standard_CString theTypeName) const |
| | Returns true if this is an instance of TypeName or an instance of any class that inherits from TypeName. Note that multiple inheritance is not supported by OCCT RTTI mechanism.
|
| |
| Standard_Transient * | This () const |
| | Returns non-const pointer to this object (like const_cast). For protection against creating handle to objects allocated in stack or call from constructor, it will raise exception Standard_ProgramError if reference counter is zero.

| | Get the reference counter of this object.
|
| |
| void | IncrementRefCounter () noexcept |

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.
