How to compute graphical data

To make it easier to obtain graphical information from Dtk_2DEntity stored on Fdt, there's a method for converting entities to Dtk_Symbol.
Dtk_Symbol is basically composed of Dtk_CompositeText , Dtk_Leader and geometrical elements.
Leaders of 2D entities can be kept as such or be converted into geometry using parameter inKeepLeaderAsLeader.

//  Constructor from Dtk_2dEntityPtr
//  inToBeConverted Entity to be converted.
//  inTextAutoFlip 
//  inKeepLeaderAsLeader to keep the leader definition put the value DTK_TRUE - only for Dtk_Dimension -.
//  the created Dtk_SymbolPtr
static Dtk_SymbolPtr Create(
     const Dtk_2dEntityPtr &inToBeConverted,
     const Dtk_bool &inTextAutoFlip = DTK_FALSE,
     const Dtk_bool & using  = DTK_FALSE );       

Then you can use following methods to retrieve main information you need :

• To retrieve geometrical elements :

  Dtk_EntityPtr  Dtk_Symbol::GetGeomElement (const Dtk_Size_t &inPos); 

• To retrieve leader elements :

  Dtk_LeaderPtr  Dtk_Symbol::GetLeader (const Dtk_Size_t &inPos);

• To retrieve text elements :

  Dtk_CompositeText& Dtk_Symbol::Texts (  );
