virtual MyDXFEntity::~MyDXFEntity ( )

inlinevirtual

Virtual destructor.

Member Function Documentation

bbox_ppoint()

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.

copy()

virtual MyDXFEntity* MyDXFEntity::copy ( void  ) const

pure virtual

Get a new copy of entity.

Implemented in MyDXFSpline, MyDXFMText, MyDXFLWPolyline, MyDXFLine, MyDXFInsert, MyDXFCircle, and MyDXFArc.

debug_print()

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

pure virtual

Print debugging information to stream os.

Implemented in MyDXFSpline, MyDXFMText, MyDXFLWPolyline, MyDXFLine, MyDXFInsert, MyDXFCircle, and MyDXFArc.

explode()

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 the entities with tranformation t. Add the tranformed entities to the database ent.

Implemented in MyDXFSpline, MyDXFMText, MyDXFLWPolyline, MyDXFLine, MyDXFInsert, MyDXFCircle, and MyDXFArc.

get_bbox()

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

pure virtual

Return bounding box of entity.

Implemented in MyDXFSpline, MyDXFMText, MyDXFLWPolyline, MyDXFLine, MyDXFInsert, MyDXFCircle, and MyDXFArc.

get_handle()

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

inline

Get entity handle.

get_layer()

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

inline

Get layer.

get_type()

virtual EntityType MyDXFEntity::get_type ( void  ) const

pure virtual

Get entity type.

Implemented in MyDXFSpline, MyDXFMText, MyDXFLWPolyline, MyDXFLine, MyDXFInsert, MyDXFCircle, and MyDXFArc.

plot()

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

Implemented in MyDXFSpline, MyDXFMText, MyDXFLWPolyline, MyDXFLine, MyDXFInsert, MyDXFCircle, and MyDXFArc.

rotate_z()

scale()

virtual void MyDXFEntity::scale ( class MyDXFFile *  dxf, double  s  )

pure virtual

Scale entity by factor s.

Implemented in MyDXFSpline, MyDXFMText, MyDXFLWPolyline, MyDXFLine, MyDXFInsert, MyDXFCircle, and MyDXFArc.

set_handle()

void MyDXFEntity::set_handle ( const std::string &  handle )

inline

Set entity handle.

set_layer()

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

inline
