Detailed Description

DXF LW polyline entity class.

Constructor & Destructor Documentation

MyDXFLWPolyline::MyDXFLWPolyline ( class MyDXFFile * dxf )

Construct line entity by reading from DXF file.

virtual MyDXFLWPolyline::~MyDXFLWPolyline ( )

inlinevirtual

Virtual destructor.

Member Function Documentation

bool MyDXFLWPolyline::closed ( void ) const

inline

Is entity closed path?

virtual MyDXFLWPolyline* MyDXFLWPolyline::copy ( void ) const

inlinevirtual

Get a new copy of entity.

Implements MyDXFEntity.

void MyDXFLWPolyline::debug_print ( std::ostream & os ) const

virtual

Print debugging information to stream os.

Implements MyDXFEntity.

virtual Vec3D MyDXFLWPolyline::end ( void ) const

inlinevirtual

Get end point of path entity.

Implements MyDXFPathEntity.

void MyDXFLWPolyline::explode	(	class MyDXFEntities *	ent,
		MyDXFFile *	dxf,
		const Transformation *	t
	)		const

virtual

Explode into entities.

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

Implements MyDXFEntity.

bool MyDXFLWPolyline::geom_same	(	const MyDXFLWPolyline &	line,
		double	eps = `1.0e-6`
	)		const

Check if two entities are geometrically same.

Checks if entity a is the geometrically same as entity b within error limit eps.

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

virtual

Return bounding box of entity.

Implements MyDXFEntity.

virtual EntityType MyDXFLWPolyline::get_type ( void ) const

inlinevirtual

Get entity type.

Implements MyDXFEntity.

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

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.

Implements MyDXFEntity.

int MyDXFLWPolyline::ray_cross	(	double	x,
		double	y
	)		const

virtual

Check for ray crossing.

Check if ray going from point (x,y) downwards (negative y direction) crosses the entity. Return 1 if crosses odd number of times and 0 if even number of times. Return 2 in case of exact crossing at boundaries. This function is used as a subroutine to inside_loop().

Implements MyDXFPathEntity.

void MyDXFLWPolyline::rotate_z	(	class MyDXFFile *	dxf,
		double	a
	)

virtual

Rotate entity around origin.

Rotate for a radians.

Implements MyDXFEntity.

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

virtual

Scale entity by factor s.

Implements MyDXFEntity.

void MyDXFLWPolyline::set_end ( const Vec3D & e )

virtual

Set end point of path entity.

Implements MyDXFPathEntity.

void MyDXFLWPolyline::set_start ( const Vec3D & s )

virtual

Set start point of path entity.

Implements MyDXFPathEntity.

uint32_t MyDXFLWPolyline::size ( void ) const

inline

Get number of vertices in entity.

virtual Vec3D MyDXFLWPolyline::start ( void ) const

inlinevirtual

Get start point of path entity.

Implements MyDXFPathEntity.

void MyDXFLWPolyline::translate	(	class MyDXFFile *	dxf,
		const Vec3D &	dx
	)

virtual

Translate entity by dx.

Implements MyDXFEntity.

Vec3D MyDXFLWPolyline::vertex ( uint32_t i ) const

inline

Get vertix i.

void MyDXFLWPolyline::write	(	class MyDXFFile *	dxf,
		std::ofstream &	ostr
	)

virtual

Write dxf file to stream.

Implements MyDXFEntity.
