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.

		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,

		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.
