Detailed Description

DXF entity base class.

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


Constructor & Destructor Documentation

MyDXFEntity::MyDXFEntity ( ) [protected]
virtual MyDXFEntity::~MyDXFEntity ( ) [inline, virtual]

Virtual destructor.


Member Function Documentation

static void MyDXFEntity::bbox_ppoint ( Vec3D min,
Vec3D max,
const Vec3D p 
) [static, protected]

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]

Scale entity by factor s.

void MyDXFEntity::set_handle ( const std::string &  handle) [inline]

Set entity handle.

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.

void MyDXFEntity::write_common ( class MyDXFFile dxf,
std::ofstream &  ostr 
) [protected]
