Detailed Description

DXF entity base class.

A general base class for all DXF entities. Contains data fields common to all entities.

virtual MyDXFEntity::~MyDXFEntity ( )
inlinevirtual

Virtual destructor.

Member Function Documentation

static void MyDXFEntity::bbox_ppoint ( Vec3D min,
Vec3D max,
const Vec3D p 
)
staticprotected

Propose a point to bounding box.

Updates bounding box value at min and max by including point p in the bounding box.

void MyDXFEntity::constructor_debug_print ( void  ) const
protected
virtual MyDXFEntity* MyDXFEntity::copy ( void  ) const
pure virtual

Get a new copy of entity.

virtual void MyDXFEntity::debug_print ( std::ostream &  os) const
pure virtual

Print debugging information to stream os.

void MyDXFEntity::debug_print_base ( std::ostream &  os) const
protected
virtual void MyDXFEntity::explode ( class MyDXFEntities ent,
MyDXFFile dxf,
const Transformation t 
) const
pure virtual

Explode into entities.

Break entity into atomic entities and tranform entities them with tranformation t. Add the tranformed entities to the database ent.

virtual void MyDXFEntity::get_bbox ( Vec3D min,
Vec3D max,
const class MyDXFFile dxf,
const Transformation t 
) const
pure virtual

Return bounding box of entity.

std::string MyDXFEntity::get_handle ( void  ) const
inline

Get entity handle.

std::string MyDXFEntity::get_layer ( void  ) const
inline

Get layer.

virtual EntityType MyDXFEntity::get_type ( void  ) const
pure virtual

Get entity type.

virtual void MyDXFEntity::plot ( const class MyDXFFile dxf,
cairo_t *  cairo,
const Transformation t,
const double  range[4] 
) const
pure virtual

Plot entity with cairo.

Plot the entity using the transformation from from the object space to cairo coordinates. The visible range is specified by range (xmin,ymin,xmax,ymax) in cairo coordinates.

void MyDXFEntity::process_group ( class MyDXFFile dxf)
protected
virtual void MyDXFEntity::scale ( class MyDXFFile dxf,
double  s 
)
pure virtual

void MyDXFEntity::set_layer ( const std::string &  layer)
inline

Set layer.

virtual void MyDXFEntity::translate ( class MyDXFFile dxf,
const Vec3D dx 
)
pure virtual

Translate entity by dx.

virtual void MyDXFEntity::write ( class MyDXFFile dxf,
std::ofstream &  ostr 
)
pure virtual

Write dxf file to stream.
