IGESSelect_SplineToBSpline Class Reference

This type of Transformer allows to convert Spline Curves (IGES
type 112) and Surfaces (IGES Type 126) to BSpline Curves (IGES
type 114) and Surfac (IGES Type 128). All other entities are
rebuilt as identical but on the basis of this conversion.

It also gives an option to, either convert as such (i.e. each
starting part of the spline becomes a segment of the bspline,
with continuity C0 between segments), or try to increase
continuity as far as possible to C1 or to C2.

It does nothing if the starting model contains no Spline
Curve (IGES Type 112) or Surface (IGES Type 126). Else,
converting and rebuilding implies copying of entities.

 IGESSelect_SplineToBSpline (const Standard_Boolean tryC2)
 Creates a Transformer SplineToBSpline. If <tryC2> is True,
it will in addition try to upgrade continuity up to C2.

Standard_Boolean OptionTryC2 () const
 Returns the option TryC2 given at creation time

Standard_Boolean Perform (const Interface_Graph &G, const Handle< Interface_Protocol > &protocol, Interface_CheckIterator &checks, Handle< Interface_InterfaceModel > &newmod)
 Performs the transformation, if there is at least one Spline
Curve (112) or Surface (126). Does nothing if there is none.

Standard_Boolean Updated (const Handle< Standard_Transient > &entfrom, Handle< Standard_Transient > &entto) const
 Returns the transformed entities.
If original data contained no Spline Curve or Surface,
the result is identity : <entto> = <entfrom>
Else, the copied counterpart is returned : for a Spline Curve
or Surface, it is a converted BSpline Curve or Surface. Else,
it is the result of general service Copy (rebuilt as necessary
by BSPlines replacing Splines).

TCollection_AsciiString Label () const
 Returns a text which defines the way a Transformer works :
"Conversion Spline to BSpline" and as opted,
" trying to upgrade continuity"
